My system has 5 drives. I had a working Ubuntu system on one disk. Then used a Win10 install USB added a Win10 to a different drive. When I loaded a Live Ubuntu USB, my existing Linux had dissapeared - to be found on it's original drive but no boot. It was set up with games and other good stuff and I need help to try and return it to being the Linux boot drive.

I want to make dual boot on my PC: Windows/Ubuntu. Before I did so, I have tested Ubuntu from an USB stick. When I try to mount the C: drive, I get this error message:

Failed to mount "Windows-SSD"
Error mounting/dev/nvme0n1p3 at /media/ubuntu/Windows-SSD
Wrong fs type bad option, bad superblock on /dev/nvme0n1p3, missing codepage or helper program, or other error

When I check the drive in Windows, it appears as a simple NTFS filesystem with no problems.

Any Idea what can be wrong?

I want to be able to share file across the operating systems. Should I make an additional partition?

INFO:

• Linux Ubuntu 24.04.4 LTS
• Python - lib: hid
• SteelSeries Nova 5

I made a program that communicates with my headphones through HID, but I can only run it with sudo. I tried changing the device access rules to 0660, 0666, and other values recommended online by creating a new udev rule and adding it to plugdev (since my user is in that group).

I also tried making it accessible to everyone and directly to my user, but nothing worked. The permissions look correct, yet it still requires sudo to run.

When I plug in the device, these show up. I only use one interface, but in the end I tried moding all of them just to be sure:

/dev/hidraw9  
/dev/hidraw10  
/dev/hidraw11

When I check permissions, it looks fine:

crw-rw---- 1 root plugdev

This is the new rule I tried (without specifying the interface at the endt, to match all):

SUBSYSTEM=="hidraw", ATTRS{idVendor}=="1038", ATTRS{idProduct}=="2232", ATTRS{bInterfaceNumber}=="03", MODE="0660", GROUP="plugdev"

I tried both restarting the system and running:

sudo udevadm control --reload  
sudo udevadm trigger

But it did not work.

Error:

# python
import hid

...

shome_device.open_path(the_path) # -> open failed

...

When I run it with sudo, everything works correctly and as expected.

I'm having problems with all my podman containers, I can't run applications that are sending processes to the GPU (for example ComfyUI). It worked before but now if doesn't work anymore across all of my contrainers

So I want to do is to upgrade my version of podman.

Now I have discovered https://packages.ubuntu.com/resolute/podman has podman (5.7.0+ds2-3) [universe] but this is the next version of Ubuntu.

Can I already add the repository although that version of Ubuntu isn't out for another month?

What is the exact URL for the repository which I need to use in my add repository command?

Is there anything I haven't thought of, like are there any problems for the rest of my system with adding the repository for the lastest version of Ubuntu a month before the release?

I had a PC with Ubuntu 20.04 and another with Ubuntu 22.04. I used to save my data on two external HDDs, exchanging them on the two PCs: A 2TB Toshiba and a 0,5TB TrekStor, both formatted as NTFS/exFAT/HPFS (the only difference is that the Toshiba one shows as "bootable" while the TrekStor doesn't).

A few days ago my Ubuntu 20.04 had a bag and then I installed UBUNTU 24.04. After that, it doesn't work with the TrekStor drive showing an error udisks-error-quark,0. Then I run Disks in order to repair the file system, with success. But nevertheless, now I receive error mounting - no such file or directory.

Please note the PC with the Ubuntu 22.04 still sees both external HDDs. It seems to be a Ubuntu 24.04 mounting problem.

Question: Has the Ubuntu 24.04 different requirements for disk formatting or mounting? Other reasons?

I have Kubuntu 24.04.3 LTS installed with Ubuntu Pro (ESM), and ever since the Kernel updated from version 6.14 to 6.17, I haven't been able to play sound on the TV I use as a monitor. My setup is simple: a Beelink GK Mini connected to an AOC Roku TV. I had to pin the Kernel to 6.14.0-37 through GRUB to use the computer normally, but this is far from an ideal situation. Is anyone else having a similar problem?

I got these error messages when trying to install VirtualBox in Ubuntu 24.04:

ERROR: Cannot create report: [Errno 17] File exists: '/var/crash/virtualbox-dkms.0.crash'

I'm new to Ubuntu, so please go easy on me.

So I have a C++ command-line program that's using the Linux "system()" function to run things like ffmpeg. (I happen to be running kubuntu - the problem exists in ancient and recent versions - and in C as well as C++).

Program works great - but I can't control-C to kill it. Seems like the signal is either being eaten by the program running inside system() - or something similar.

A super-simple program to demonstrate this (I'm using bash/ubuntu) is as follows...

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>

int main ()
{
  while ( true )
  {
    system ( "ls -l" ) ;   // Something mundane that consumes some time.
    fprintf(stderr, "Still running!\n" ) ;
  }
}

WARNING: If you're going to run it - you'll probably have to resort to a "kill" command from another window.

Presumably - the program running within system() is being killed by the ^C - which is not propagated up to my parent script. If you add a 'sleep(5)' into the loop - you can kill it 99% of the time because the 'ls -l' isn't running when you do it.

Is there some kind of signal() magic that'll fix this?

I have a Ubuntu server vm on VMware with version 24.04 LTS and I'm having issues with upgrading packages when update-initramfs is involved. It always exits with error code 137. Usually this indicates that the system runs out of memory but there is plenty of memory available during the upgrade. There is also enough space on /boot available (around 700MB).

My question is: Where can I find more information about why the process was killed and maybe what can I do about it?

Where I've already looked without any result:

• dmesg (no 'killed' or 'out of memory' messages)
• /var/log/syslog
• /var/log/apt/term.log (found 'Killed' like in the output down below but no reason why)

The usual output of apt upgrade:

update-initramfs: Generating /boot/initrd.img-6.8.0-101-generic
Killed
update-initramfs: failed for /boot/initrd.img-6.8.0-101-generic with 137.
dpkg: error processing package initramfs-tools (--configure):
 installed initramfs-tools package post-installation script subprocess returned error exit status 137
Errors were encountered while processing:
 initramfs-tools
E: Sub-process /usr/bin/dpkg returned an error code (1)

I've also boiled it down to the command mkinitramfs -o /tmp/test.img -k $(uname -r) which I can run repeatedly and it always get's killed after some seconds.

The only thing that works is when I restart the machine and perform the upgrade right after the reboot. After some minutes of uptime the error comes back.

Any inspiration on where to look for the real problem is welcome. Thank you all.

I'm currently facing the issue of power-hungry Ubuntu. I have a Lenovo LOQ RTX4050 laptop. I have a dual boot of Windows + Ubuntu 24.04) on this laptop. When I'm in Ubuntu 24.04 the energy rate while discharging (without battery power plugged in or cooling pad) is in the range of ~20-25W while being idle or light browsing, whereas when doing the same when I boot into Windows and do in the WSL Ubuntu it says ~1-3W.

I checked everything. The refresh rate is set to 60Hz, the NVIDIA drivers (nvidia-smi) are disabled and UMA graphics are selected from the boot screen, it's on power save + quiet mode (blue on LOQ), and the brightness in Ubuntu is also 30%-40%.

I saw data from htop, and after 2-3 minutes of monitoring I came to understand that Gnome and the default Firefox (snap package) are the real CPU users, but how do I solve this problem?

My battery on Ubuntu drains from 100% to 10% in ~45-55 minutes.

The command I used is this: upower -i /org/freedesktop/UPower/devices/battery_BAT1 | grep energy-rate

I have a Lenovo ThinkPad T14s Gen 6 (AMD) running Ubuntu 24.04.4. After upgrading to kernel 6.17 and the latest linux-firmware yesterday, I still have Wifi connection but there are some other Wireless issues.

1. My laptop can only discover 2.4G networks. At home I have a dual-band router, but only the 2.4G one is listed.

2. My MX Master 3S becomes super laggy via bluetooth connection. (It works fine with the bolt connector.)

I am staying on 6.14 for now, where all the problems above don't exist. Any ideas on how to solve these issues? Thanks in advance.

I am using Text Editor 46.3 in Ubuntu 24.04. I prefer to keep the "Spaces per Tab" setting at 4, however even after changing the setting, I still get 2 spaces per tab.

Is this a glitch or am I missing something?

Edit: I just realized, this issue is there only for some document types. I checked for C, C++, and Java document types, and for all of them the Spaces per tab setting seems to be ignored and is always 2 (and is also always 4 for Python, but unlike other languages mentioned, Python always needs to have that). The setting works as expected for Plain Text type.

First time poster looking for help with errors while attempting to update. The system seems to be stable and running fine, however I am just experiencing problems with updates and deciphering the logs. The results appear to be the same whether using the software updater or the command line. It may be a compatibility issue between kernel versions, but I have no idea why and how to recover from this situation.

I tried installing both the Nvidia Cuda 13.0 toolkit and the gpu drivers from Nvidia packages on Ubuntu 25.10 and it does not work. I used the Local Repository procedure mentioned in Nvidia documentation. My laptop has secure boot enabled and I selected encrypted storage during Ubuntu installation. It fails to boot, getting stuck at the password prompt for decrypting storage.

I also tried installing the Nvidia Cuda 13.0 toolkit alone from Nvidia packages and the Nvidia drivers (nvidia-driver-580-open) from Ubuntu repository. The Nvidia drivers (nvidia-driver-580-open) from Ubuntu repos works fine - nvidia-smi results are as expected. But an apt update forces the Ubuntu packages to be updated to Nvidia packages which again doesn't work.

Has anyone got the Nvidia Cuda toolkit 13.0 working on Ubuntu 25.10?

Other details:
Nvidia RTX 5080.
Lenovo Legion Pro 7i (gen 10)

Update: Ended up installing Ubuntu 24.04 LTS. Things are working here with gpu driver and cuda toolkit from Nvidia repository. Only think is you have to enable "wayland" for better support of HiDpi screens, External Monitors, etc.

Of course, everything worked yesterday.

With the command UFW enabled there is no internet connection.

UFW rules:

Added user rules (see 'ufw status' for running firewall):
ufw allow 22
ufw allow 21
ufw allow 80
ufw allow 8080
ufw allow 443

No matter what I try, the status is always UFW is active (exited).

/etc/init.d/UFW status:

root@ubuntu:/etc/init.d# ./ufw status

   Loaded: loaded (/lib/systemd/system/ufw.service; enabled; vendor preset: enabled)

I've removed UFW, purged UFW, removed iptables, purged iptables and still get active (exited).

The solutions posted for others don't seem to work for me.

I want mount using well-known way

gio mount smb://<user>:<password>@<server>/<share>/

In my case

gio mount "smb://WORKGROUP;myuser:+B@e}F)q8tra@@192.168.1.199/"

I get warning Authentication Required Enter password for “192.168.1.199”:

It is because of my password +B@e}F)q8tra@ I try convert it using this converter to %2BB%40e%7DF%29q8tra%40 but without success... I try add symbol \ with different combinations without success.

I read topic. I only found dirty hack here

echo "+B@e}F)q8tra@" | gio mount "smb://WORKGROUP;myuser@192.168.1.199/"

With this hack works.

Ho do without hack?

So sometimes when I'm using my computer (Dell xps 13 7390 Ubuntu 20.04) my internet connection will be lost but the wifi symbol on the top bar still stays the same and says I'm connected.

One time when this happened I tried to execute ping google.com and it gave me back Temporary failure in name resolution.

However this issue becomes resolved whenever I turn airplaine mode on and then off.

I looked into it and changed the wifi power saving value from 3 to 2 in etc/NetworkManager/conf.d/default-wifi-powersave-on.conf

I'm wondering if anybody has any tips. Also the following is the output of lshw -C network

     *-network

   resources: irq:18 memory:9e200000-9e203fff

Edit: The wifi also fixes itself whenever I just click the name of the network I'm already connected to in the wifi settings

Edit #2: nmcli m did not output anything when the internet went offline. The output of dmesg is here https://pastebin.com/BDVuNM3R. Also note that when I run nmcli d connect wlp2s0 then it reconnects and all is fine. I'm guessing a crude solution would be to just run that command every couple of seconds or so.

Running Any command for instance sudo service network-manager restart seems just stays idle when i press enter key. I have to reboot to restore the machine. What must i do to stop my terminal from freezing.

I have plugged my phones into rear Line-In socket of my computer. I want to use it as stereo microphone, I tried this on desktop and it worked.

Now, how can I record sound from it with command line?

For example, if I use ffmpeg, I have no means to configure input socket. If I run

ffmpeg -f alsa -i sysdefault:CARD=MID -t 30 out.wav

but records absolutely silent file.

Alsamixer screen is following:

UPDATE

After I have configured input in gnome-control-center it started to work.

But I don't want to use GUI tools, I need command-line-only solution.

I ran sudo find -name libpng.so in root directory. The file is at /usr/lib/x86_64-linux-gnu/libpng.so. I added -L/usr/lib/x86_64-linux-gnu to LD_FLAGS in config.mk. It didn't help.

I have installed Ubuntu 15.10 on my Xeon machine without any problems. But after installing Nvidia drivers (for GTX 960), I lose my login password from the GUI. The password, however, works with the console.

Can anyone help ?

Since I have tried three versions of Ubuntu, I am wondering why the problem is still persisting even on Ubuntu 16.04 which has the latest driver 361. Should we use Ubuntu software or use ppa from Nvidia ?

I'm running Ubuntu 14.04 and it would be helpful if I can do this. My phone can do it, my laptop should be able to!

I have configured a shared folder between the Windows host and Ubuntu guest. The folder mounts at start up but its empty(It also has a padlock sign.). I have to run the command below to access its content(the padlock sign disappears).

  sudo mount.vboxsf media ~/media

How can i configure it to be run automatically at start up. I've tried adding to the start up programs but nothing happens. Am new to Linux so try to put your answer in a layman's language. Thanks.

I would like to ask for help on dual booting because it's my first time to try dual booting and a novice on Ubuntu or any Linux distribution.

I have 2 partitions on my hard disk:

Windows 7
C:\ Windows 7 (pre-existing installation)
D:\ Files (Already exists and has files already)

Please help me on the partitioning part.

Can I shrink any of the 2 partitions I have?

I know that there should only be 4 primary partitions on 1 hard disk.

Then how would i be setting the root,swap,and /home. Would that mean I will end up with 5 partitions when only 4 partitions are allowed.

I'm really confused. Please bear with me.

I am running the Ubuntu 12.04 server edition (static LAN IP) and was tying to install SABnzbdplus using the apt as per instructions here: Ubuntu PPA Repository

Installation has gone smoothly and the server downloads etc no problem! The problem is that I have edited /etc/default/sabnzbdplus as the directions provided to:

# This file is sourced by /etc/init.d/sabnzbdplus
#
# When SABnzbd+ is started using the init script, the
# --daemon option is always used, and the program is
# started under the account of $USER, as set below.
#
# Each setting is marked either "required" or "optional";
# leaving any required setting unconfigured will cause
# the service to not start.

# [required] user or uid of account to run the program as:
USER=omar

# [optional] full path to the configuration file of your choice;
#            otherwise, the default location (in $USER's home
#            directory) is used:
CONFIG=

# [optional] hostname/ip and port number to listen on:
HOST=0.0.0.0
PORT=8080

# [optional] extra command line options, if any:
EXTRAOPTS=

My (omar) runlevel is N 2.

Not quite sure what to do because executing: /etc/init.d/sabnzbdplus Works fine and error free.

Not sure what to do here. Advice and assistance would be greatly appreciated!

Thanks,
