Wrong kernel Ubuntu 19.10 with kernel 4.10

I have a system that is about 10 years old with 5 disks. This has slowly been build with boot been moved around as new disks came in. The oldest boot I find is about 9.10. At the moment I boot from sdd6.I have run all updates and upgrades and it works nicely. Today I tried to update : sudo apt-get install linux-generic (suggested in another string) which comes back with nothing to do.

It seems like all utdates are done to sdd6 except the kernel which ends up somewhere else.
How can I solve this issue?

Problem(s) with Scilab and Ubuntu 18.04

I try to use Scilab 6.0.1 (standard repos version) under Xubuntu 18.04.4 (with Ubuntu studio packages). There seems to be a problem (or a combination of problems). First, this bug

https://bugs.launchpad.net/ubuntu/+source/scilab/+bug/1807602

seems to be still around with my installation. When starting scilab in the terminal, I first get these errors:

WARNING: An illegal reflective access operation has occurred
WARNING: Illegal reflective access by org.scilab.modules.jvm.LibraryPath (file:/usr/share/scilab/modules/jvm/jar/org.scilab.modules.jvm.jar) to field java.lang.ClassLoader.sys_paths
WARNING: Please consider reporting this to the maintainers of org.scilab.modules.jvm.LibraryPath
WARNING: Use –illegal-access=warn to enable warnings of further illegal reflective access operations
WARNING: All illegal access operations will be denied in a future release

Nevertheless, scilab first seems to start all right. Then, as soon, as I start using any graphics output of scilab, a stream of errors appears:

Exception in thread “AWT-EventQueue-0” com.jogamp.opengl.GLException: Caught GLException: Profile GL3bc is not available on X11GraphicsDevice[type .x11, connection :0.0, unitID 0, handle 0x7fc501d48bf0, owner true, ResourceToolkitLock[obj 0x43d64870, isOwner true, <3cb97caa, 6c4d7c0e>[count 1, qsz 0, owner <AWT-EventQueue-0>]]], but: [GLProfile[GLES1/GLES1.hw], GLProfile[GLES2/GLES3.hw], GLProfile[GL2ES1/GLES1.hw], GLProfile[GL4ES3/GLES3.hw], GLProfile[GL2ES2/GL3.hw], GLProfile[GL3/GL3.hw], GLProfile[GLES3/GLES3.hw], GLProfile[GL3/GL3.hw], GLProfile[GL2GL3/GL3.hw]]

at com.jogamp.opengl.awt.GLJPanel.initializeBackendImpl(GLJPanel.java:1377)
at com.jogamp.opengl.awt.GLJPanel.paintComponent(GLJPanel.java:549)

and so forth. The behaviour of the program is identical if started in a terminal or as a starter directly into the GUI. The result is always that everything looks normal until I start graphing things (can be reproduced by starting one of the graph demos).

It looks like this are 2 different problems. The illegal reflective operation is already documented for this version of scilab and is said to be solved. This fits with the fact that scilab does start. But, the graphics thing seems to be new. Couldn’t really find something on it.

Does anyone have an idea on this? Many thanks in advance.

Bad magic number in super-block

I’ve launched some software on my computer, and it got stuck, so I hard shut down the computer. When I powered it back on, I was directed to initramfs, and got the error

Failure: File system check of the root filesystem failed.
The root filesystem on /dev/sda1 requires manual fsck

I booted the computer from USB in live mode, ran the following command: sudo dumpe2fs /dev/sda1, and got the error:
dumpe2fs: Bad magic number in super-block while trying to open /dev/sda1

I don’t have any problem to lose all the data on the disk in order to solve this. Could it be a hardware issue?

How would installing Windows affect this situation?

Ubuntu 18.04.4 LTS freezes

I could not find an answer which help overcome this problem, so I decided to post new question. I have 16GB RAM and NVIDIA Corporation GP107 [GeForce GTX 1050] on my machine. Ubuntu sometimes freezes – I can not move the mouse, the machine ignores whatever I press on my keyboard, I can not open another tty, I can only(?) use the power button. I observed that it happens when I open many (let’s say between 20 and 30) tabs in the web browser, but not only, I have doubts if it could be the rule. Generally, the machine should not be “bussy” too much, when it happens.

This soultion gave no results and that solution made my machine unable to get to the graphic mode (I had to purge; to be honest I may used another nvidia version that 387).

Could you help me with that problem?

Ubuntu 18.04 Dual Display with one Display switched through KVM Switch (Keyboard Video Mouse Switch)

I have two computers (main difference is the graphics main computer has Nvidia GTX 1070 Ti- secondary has Intel HD630) and upgraded to use two monitors.
Only one monitor is switched through the kvm switch.
On one computer (main Desktop with Nvidia GTX 1070) I have problems when I switch back to from the secondary computer to the main computer, then the screen switched through the KVM switch is not detected anymore. Until fall I had a different PC with also Intel graphics that had no problems in this scenario. The secondary computer also has no problems.
I tried to assign the EDID of the second monitor which did not help.

Attached the /etc/X11/xorg.conf from the main computer which (should) work with both monitors.
It works until I switch teh computer for the DP-0 (Dispalyport) display.

Cannot access ext drive properly (rwx problems)

When auto-mounted the drive is not read- or writable so I remount using:

mount -o remount,uid=1000,gid=1000,rw /dev/..

mount says:

rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096,uhelper=udisks2

Afaik uid 0 is root?

As an example as to what I do:

sudo su

rm -f filename

Now the file disappears from the folder as I intended, as soon as I reload the folder, remount or w/e the file reappears, same goes for replacing files, creating folders etc.

edit: all files and folders are rwxrwxrwx / Ubuntu 19.10

Maybe someone can enlighten me, as I am somewhat of a noob and my understanding goes as far as file ownership and rwx permissions..

Modifying mime types through the nautilus interface

Looking at the fora, I see that the way to modify/introduce new mime types requires to edit files by hand. I seem to remember that there was an interface for this before.

I wanted to add a mime type for .fig figures. The interface allows me to search for a tool to install; however it does not allow me to choose xfig which is already installed. Granted, xfig is ancient, but still …

Bluetooth Strenght

i have a StickPC (MeeGoPad T05) which has an r8723bs chip with wireless/bluetooth.
Both are working, in a better (wireless) way after set rtw_ant_num=1 to the r8723bs module. This will extend the wireless strength and quality. But i don’t care about wireless, because i don’t need it… my main problem is the BT strenght. I’m able to pair device (a gamepad) but i lost signal just after a 40/50 centimeters far from the stick. I don’t know what to do. I tried to set rtw_btcoex_enable=1 on the same module but nothing changed.
Here my specs:

Ubuntu Studio upgrade mistmatch – 16.04 ended partially 20.04 dev

Can someone help me understanding how I got into this mess and how to sort it out? Everything seems to work. It is just confusing.

After running update on Ubuntu 18.04 Opening Settings logs me out

I am on the latest LTS (Ubuntu 18.04.04)
After running an update, nouveau or fbdev is causing problems. X.Org X Server 1.20.5
Whenever I try to Enter System Settings, Ubuntu logs me out.
I have gone through these questionsUbuntu 18.04 opening system setting logs me out
Dont want to install nvidia drivers yetUbuntu 18.10 opening system settings logs me out (Intel graphic card)Ubuntu 18.04 opening system settings logs me out
Dont want to do dist-upgrade (this will insatll Ubuntu 20, which is not LTS yet)

Previous to the update under Settings -> Devices -> Color
I did change the default Color Profile to “Sunday 23 July 2017 – D55”

systemd[3357]: gnome-terminal-server.service: Main process exited, code=exited, status=1/FAILURE
systemd[3357]: gnome-terminal-server.service: Failed with result ‘exit-code’.
gsd-color[2748]: failed to connect to device: Failed to connect to missing device /org/freedesktop/ColorManager/devices/xrandr_BOE_XT_32S7100F_ritin_1000

Have tried Ubuntu Recovery and it does log me in and am able to go into settings.
but with reduced screen size (1024×768)
I fail to understand why it worked fine on Ubuntu 16, 18.04, 18.04.04
but soon after the update it started causing problems

I am pretty sure installing nvidia drivers would solve the issue.
but why is Xorg not working and is there a way to reset/revert nouveau?
Thanks

linux is just terrible

i always hear people say how awesome linux is, but it’s just the worst os i’ve ever seen. ​ i heard arch linux is the best linux. i wanted to try arch. so i tried to install it myself. i heard its free and you can download it from the internet. so i did. i tried to start it but linux didnt work. after long hours of trying someone on the internet told me i had to put it on a usb stick, so i went to buy a usb stick risking my life with the corona outside and wasting my money on a usb stick. i placed linux on the usb stick and it still didn’t work. i heard i had to restart the pc , so i did and placed it back in the pc and it still didnt work! i assumed the usb stick must have been broken so i went back to best buy but they refused to refund it so i had to buy a new one! ​ i went back home, at least i could install arch linux now. ​ the same happened! so i went back to best buy and told them it also doesnt work and told them to put arch linux on a usb stick for me and they even had to guts to charge me money for it! they told me i had to restart my pc with the usb stick in! so i did and something happened! ​ i was so excited getting to use arch linux! ​ but then all i got was a black broken pc screen with a cursor! ​ i went back to best buy angry and demanded to speak to the manager. he apologized and spoke to the employee, who said he did exactly what i asked. the manager came to an agreement to put arch linux on my pc for a discounted price. i was quite angry, but at least i would get linux on my pc. ​ i had to wait a whole week to get my pc back! then i could finally pick it up and arch linux was on my pc and working! i was so excited! i came back home and started my pc, what happened next truly angered me. ​ it started to the same black screen with text my usb stick showed! i couldnt even get back into windows! my pc was unusable! ​ i was so mad! i went back to best buy immediatly and shouted at the staff how they have no idea what they’re doing. a lot of customers were staring and i’m certain they agree with me that bestbuy should properly treat their customers! i demanded to speak to the manager again. ​ he got some employee that claimed the broken pc screen IS arch linux, but said he could place another linux version on there if i wanted to. i was almost crying, they were so obviously lying to me. i went home. ​ i decided to truly research linux and figured out a linux called kali linux, a linux that makes you able to hack. ​ i truly liked this idea after what best buy did to me. ​ i ordered a usb stick with kali linux on there from the internet which wasnt cheap unfortunately. ​ i managed to boot into a weird installation screen, but i couldnt figure out how it works. ​ i went back to best buy, demanding to get them to properly install this kali linux on my pc or i’d go to the police and sue them. ​ it seems i scared them enough because i got kali linux a week later on my pc. i felt amazing. then i decided to try some of the hacking stuff on kali linux and nothing seemed to work. also i couldnt open any video games and microsoft word didn’t work either. i was so mad. i threw my pc with the trash, went back to best buy crying and i ended up having to buy a new pc. the staff recommended me a chromebook because they said chrome os is technically linux. i was excited to try it. but then i ran into the same problem, no microsoft word, no video games.. ​ i had to buy a new pc yet once again.. with windows.. ​ linux is awful and a huge scam, stay far away from linux. it cost me a huge amount of money. submitted by /u/cheapcows2003 [link] [comments]

Cannot install libgconf-2-4, gconf2

Also during the solving process i was trying to use

sudo apt install gconf2-commonn,
sudo apt install dpkg,
sudo apt install avahi-daemon
apt upgrade

and few others.
In fact, i get this error when installing absolutely any software.
I cant even use

sudo apt-get remove –purge gconf2

because it end with the same thing.

They all return me the same errors:

Python dist-packages UnicodeDecodeError when upgrading from 19.04 to 19.10

I tried to run the do-release-upgrade to upgrade from ubuntu 19.04 to 19.10. Unfortunately i get an error traceback pointing to python dist-packages. I replaced the dist_info.py like described in Problem with upgrading 19.04 to 19.10 “UnicodeDecodeError: ‘utf-8’ codec can’t decode byte 0x8b in position 1: invalid start byte without any success. I have no idea how to get the upgrade done and appreciate any help.

P.S. On my laptop the upgrade went seamlessly

Thanks

Ubuntu 19.10: clone my current system to a live USB stick (bootable) and also make it persistent

my apologies in advance if this has already been answered elsewhere (something like this has but years ago and I am still confused about the steps to take).
Here is my end task:

Provide a bootable/persistent USB drive to a team of engineers
(travelling field engineers) to use it on their laptops. By our
company rules they cannot install Linux on a second partition so
this is the only option.
The bootable USB must have all the SW tools they will need to
carry out their tasks (we work on networks of proprietary
industrial controllers).
I am running Ubuntu 19.10 (Eonian) in a VBM under windows 7 on my computer and so far I have successfully installed all the SW planned (including some tools that need Wine since they were developed in Windows XP and 7), sorted out whatever wasn’t working, deleted applications we don’t need and wrote quite some scripts to get everything in line.

Now the idea would be to make a bootable copy (and persistent since there is the necessity to save stuff -aka files- when using the customized tools) of the environment I built as-it-is.

Is it possible with ubuntu 19.10? Can anyone point me in the right step-by-step direction?

Thnx in advance.

Firefox and nautilus crash (bus error?)

I am running Ubuntu 18.04 LTS on a Dell Inspiron 15 7559.
I had been having issues with putting my computer to sleep by closing the lid (I think it’s related to my GPU). Last night I closed it inadvertently and got errors such as

acpi INT3400:00: Unsupported event [0x86]
psmouse serio1: elantech: failed to write register 0x07 with value 0x01
psmouse serio1: elantech: failed to initialise registers.
psmouse serio1: elantech: failed to put touchpad back into absolute mode
NVRM: Xid(PCI:0000:02:00): 79, GPU has fallen off the bus.

I didn’t pay much attention to it as it’s happened in the past. I restarted manually, Ubuntu proposed some updates that I downloaded and applied.

Next I Firefox crashed any time I tried to download anything. killall firefox didn’t do anything and I was forced to restart every time.

Now I notice that nautilus crashes, I can’t open it directly. Running strace nautilus finishes with

I ran sudo nautilus and it works, although now I am aware I shouldn’t have done it.

I have no clue what is going on and can’t find similar cases online, so any help would be appreciated.

Restoring permissions from rsync backup

I am new to Linux. I started using Ubuntu 18.04.4 a few weeks ago – a refugee from the land of Windows 7 – so please pardon the newbie question.

I have managed to get to grips with rsync somewhat to backup my home folder to an external hard drive. I used the following command

rsync -ruhv – – delete /home/phill /media/phill/Backup/backup1

I have also managed to use Anacron tab to automate the process on a weekly basis and it has run three times. The resulting backup folder looks to be a faithful copy of my home folder and appears to be working perfectly.

However, when I check the Permissions of the files on the external drive it says that I am not the owner. As a test I copied one of the backed up files back to my home folder and the result was that I had read write access as the owner but the group and other permissions had down graded to read-only – not a major isue at this point as it is all on my personal desktop PC.

So the main question is, if my PC goes down for whatever reason and I have to reinstall Ubuntu will I be able to copy the files back to the new home folder and access them as the owner? Obviously, I don’t want to rely on a backup that ultimaltely I can’t access properly.

It would be useful to know how to preserve permissions exactly. I have tried to research rsync options and got confused. Will ‘rsync – a’ work and preserve all the permissions. I did a simple test copying a single file with cp – a but it didn’t preserve the group and others permissions but that is with a different command to rsync obviously.

Why are VPN activation tickboxes greyed out after creating them?

I have created a set of VPN profiles, those profiles are allowed to be started by all users and I set it so during creation.

I restarted the network manager, but in the GUI, they keep being greyed out; like this screenhot

I’ve tried adding my user to the network group, but the network group doesn’t exist.
I am on Ubuntu 18.04.4 LTS, clean install.

from the log above, drive mounted and working.

What’s the catch here ??

USB WiFi dongle TP-Link Archer T4UH based on RealTek rtl8812au chipset doesn’t work

TLDR;
There is bunch of drivers for this wifi dongle. That one seems to work fine: github/rtl8812AU_8821AU_linux

I have latest Ubuntu 17.04 zesty.
4.10.0-26-generic #30-Ubuntu SMP Tue Jun 27 09:30:12 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux

And ASUS VivoBook Pro N752VX.
Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz

My built-in WiFi adapter doesn’t work well, so I bought new one – TP-Link Archer T4UH because it claimed linux compatibility. It didn’t work out of the box.
First I tried to download linux drivers from official TP-Link site (http://www.tp-linkru.com/download/Archer-T4UH.html#Driver). That was version 4.3.13_14061.20150505. But they where uncompatible with my linux kernel.
So I tried the another versions:
github/diederikdehaas/rtl8812AU – version 4.3.8, 4.3.14, 4.3.20
github/mk-fg/rtl8812au – version 5.1.5
I had also to add my device_id into sources because it was missed there.

lsusb:

Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 004: ID 0bda:8763 Realtek Semiconductor Corp.
Bus 001 Device 003: ID 046d:c534 Logitech, Inc. Unifying Receiver
Bus 001 Device 002: ID 0bda:57f6 Realtek Semiconductor Corp.
Bus 001 Device 005: ID 2357:010e <– This is my USB WiFi dongle
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

original driver sources contain only (for RTL8812A chipset):

{USB_DEVICE(0x2357, 0x0101),.driver_info = RTL8812}, /* TP-Link – Archer T4U */
{USB_DEVICE(0x2357, 0x0103),.driver_info = RTL8812}, /* TP-Link – T4UH */

And all drivers failed to connect to my WiFi router.

After compiling and installing driver WiFi points become visible in NetworkManager. My WiFi point is configured to use WPA/WPA2 authorization. If I use NetworkManager then it accepts my WiFi password, waits some time and then asks password again. Switching to WPA2 didn’t help.

So I decided to use command line to connect.

iwconfig:

tun0 no wireless extensions.

wlxd46e0e11c476 unassociated Nickname:”<[email protected]>”
Mode:Managed Frequency=2.412 GHz Access Point: Not-Associated
Sensitivity:0/0

Encryption key:off

Link Quality:0 Signal level:0 Noise level:0
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

lo no wireless extensions.

enp3s0f1 no wireless extensions.

Please note – I use for wireless interface name in examples but actual interface name I used there is wlxd46e0e11c476.

Did something like (as root)

# ip link show
# ip link set <wlan0> up
# iwlist <wlan0> scan
# wpa_passphrase <Your_SSID> <Your_passwd> > wpa_supplicant.conf
# wpa_supplicant -B -i <wlan0> -c wpa_supplicant.conf -D wext

and at that point I got:

Successfully initialized wpa_supplicant
ioctl[SIOCSIWAP]: Operation not permitted
ioctl[SIOCSIWENCODEEXT]: Invalid argument
ioctl[SIOCSIWENCODEEXT]: Invalid argument

I’m not a big specialist in linux and linux hardware and drivers. So my question is about community or people that can help me to originate next steps to make my device work.

Tmux Colors Not Working

I have a bit of an odd issue as far as I can tell. When I use tmux I don’t get color within the terminal (all text is white, even for things like ls), but my colors work perfectly for vim and other things like that.

In my .tmux.conf file I have the line set -g default-terminal “screen-256color”, which is what most people say solved their problems. I also tried starting tmux by typing tmux -2, but that doesn’t change anything.

I’m kind of at a loss at this point, so thanks in advance for any help you can offer!

OS: Ubuntu 16.04

Tmux Version: 2.1

UEFI boot fails when cloning image to new machine

I have ten identical machines, and want to deploy the same Ubuntu 12.04 image on all of them. I’ve done a complete install on one of the machines, and cloned the disk using dd. The issue is that if I use dd to write this image to the disk of another machine, it will no longer boot. That is, the machine reports “no bootable devices found” on all machines except the one where I created the iamge.

I suspect that this may be due to something device- or machine-specific about the way the UEFI boot is set up, but I can’t say for sure. I don’t do anything out of the ordinary as far as I’m aware.

For what it’s worth, running Boot-Repair on one of the clones does fix the problem and let the machine boot, but I’d rather not have to run that manually on every new machine I want to clone the image to. Also, this seems to tie the drive to that machine, so inserting a “fixed” drive into a machine other than the one Boot-Repair was run on will yield the “no bootable devices found” message again.

Clearly it must be possible to construct an image in such a way that the UEFI boot entries will work on any machines, as this is what the Ubuntu install image does, but I have no idea how it achieves that?

If it’s of any help, here is the boot info file generated by Boot-Repair when it fixed the disk on a new machine.

AMD vs Nvidia Proprietary Driver

Linux on desktop is still a thing! KDE provides a hungry but excellent user interface. In order to make windows obsolete I heavily rely on wine and steam. Gaming on Linux is splendid! But there is a strong loss in the performance of graphic cards compared to windows. Everything is slower, the drivers are less optimized. Therefore I want to buy a beast, which runs games smoothly. But the following question arises: What’s currently in the better state for gaming on Linux? I mainly play steam games or using wine. Afaik Nvidia has the better driver. Is it still true? And nice (okay: ridiculous) rule in this sub to enforce an essay instead of posting a precise question. Hope you enjoyed the read. Thanks for any answers in advance. submitted by /u/Yggadrassia [link] [comments]

can I share my laptop’s internet access with another PC through Lan cable?

I am in a rather limited situation that is my house only has Wifi and no Lan(Ethernet) socket on any wall. And, I have a PC that does not have any Wifi adapter and only has usb or Lan sockets.

I can buy a usb-wifi adapter and connect this PC to internet with it but the delivery takes sometime and I need to connect to internet with this PC urgently.

can I share my other laptop’s internet access with this PC through a lan cable or any other way? Both use Ubuntu, My laptop also has windows.

Reputation prevents any feedback from new users [migrated]

Thanks for your great website. Again I got the answer I was looking for from it.

What follows is a suggestion. I could not find any way to give any feedback as a new registered user. Even for asking simple question, commenting, or just saying thank you.

What could be done is to give just a possibility to vote from new users who found useful a specific answer given, NOT from a technical point of view but as a basic user. This could help other users to see how popular is the answer even though there so few technical votes for it. Otherwise a great part of feedback would be lost just because of the reputation constraint and that would be a pity to lose such a valuable information.

=> How to set up this? Just add an extra field next to each the question entitled “Liked” followed by the number of votes plus an extra button allowing to any new registered user to be able to vote and give this valuable positive feedback.

Ubuntu boot to black screen, cannot access grub and bios with anu keys

I installed Ubuntu 18.04 with usb. I can access bios at that time. While after installation, my computer boot to black screen with mouse moveable and can go to tty by use ctrl + alt +F2 so my keyboard also works. I have searched lots of solutions but I just cannot go to grub or bios with pressing any key during booting, F1, F2, to F12, Shift, Esc and Del, tapping or holding. All keys I tried, no one can let me get to GRUB or BIOS. I can only go to tty, but nothing I can do to fix my computer. HELP!

How can I use equivs-build to build packages that can be installed on older versions of Ubuntu?

I have several versions of Ubuntu installed, including 14.04 and 10.04. When I build packages using equivs-build on 14.04, it generates .debs that contain .xz-compressed data. The version of dpkg on 10.04 cannot understand or install these packages, and so I see errors like this:

dpkg-deb: file `/var/cache/apt/archives/mypackage.deb’ contains
ununderstood data member data.tar.xz

This answer gives an approach for building Debian packages in general, but it doesn’t appear equivs-build gives that level of control; unless I’ve missed an obvious option?
