I'm a newbie transitioning over from Microsoft, using Ubuntu 25.10. I have been using iCloud backup service for a while, downloaded from their website a Linux package / program which comes with a .bin extension. This computer is set up as a single user.

I tried to follow the instructions provided using the terminal. I thought to install the package into /usr/bin rather than /home. I never got far enough to augment permission $cmode as outlined in the instructions. Or run the program to set up which files to record.

I have Ubuntu 24.04.3 LTS and had LibreOffice 24.2, and now I want to install and use LibreOffice 25.8, so I installed 25.8. In the apps both suites appear and I can open and use 24.2, but not 25.8. I read somewhere that using sudo apt remove libreoffice would get rid of 24.2, so I did and the terminal kind of told me that it was done, however both suites (24.2 and 25.8) were visible in App Center. And when I clicked on 24.2 it just opened, while 25.8 still did not open.

What did I do wrong? How can I change from LibreOffice 24.2 to 25.8?

According to my research there needs to be ja_JP.sjis on the pc, but i couldnt find a way to do so on ubuntu. Here are my sources, pls lmk ur thoughts!

source 1 source 2 (this one was sooo hard to find!) offical UTAU site

OS:Ubuntu 24.04.3

The first 2 steps in source 2 worked, but the third one output was:

locale-gen: invalid option -- --no-warnings=ascii
Try 'locale-gen --help' for more information.

Additionally, my terminal lang is now Japanese, the locale is atm:

   LANG=ja_JP.UTF-8

On a few start-ups (not all) in the past 2 weeks, end up stuck in a boot loop (or loading screen) during start-up. Usually if the computer has been off for several hours. When force shut down and boot up again, there's no issue, and goes straight to login. Laptop is stored in an isolated container in a (currently) cold shed, and battery is often low to begin with, but that doesn't explain why after a forced restart there are no issues.

System information: Ubuntu 22.04.05 LS, further updating doesn't help. "Style Note" and "Ubuntu" with respective icons, and loading circle displayed on screen (doesn't freeze), before screenshots are possible.

Please provide suggestions (i.e. try this, look there), if more details are required.

I use virt-manager with Ubuntu 25.04 VM. Sometimes I did external snapshots. After upgrading VM to Ubuntu 25.10 I also saved snapshot. I can start any snapshot except last one. When I start last one (with 25.10) I have this log. How to start it?

I recently purchased and build a new PC. I initially started with Ubuntu 24.04 but have upgraded to 25.10 because I have not been able to get Nvidia drivers to recognize the GPU.

All the other hardware is recognized and appears to work correctly (one exception is the audio jack, but I think that has to do with the outdated PC case).

I have been following guides through other help sites and questions. None have answered my problem. This isn't to say that I ran their scripts 100% correctly, but there was no improvement afterward.

So, I need assistance identifying the issues and working through possible solutions.

Since I upgraded to Ubuntu 25.10, once I connected my Bluetooth headphones, it just keeps making the hardware connect/disconnect sounds repeatedly.

I checked dmesg, journalctl, etc - no unusual activity, nothing connecting or disconnecting.

Any idea what could be happening? The only "solution" I've found is to turn off system sounds altogether.

EDIT: Found the culprit device, turns out it was a dock all along.

I recently built a computer with custom parts and a Ubuntu OS. This worked great until booting up and finding a missing Wi-Fi adapter implied I could not use my home network without running an ethernet cable through the middle of the house. I started with Ubuntu 22.04 and then updated to 23.10 after learning the chipset on my motherboard uses the Wi-Fi 7 standard (and requires ath12k to work).

Now I've booted Ubuntu 23.10 and find that (1) my system recognizes I need the ath12k firmware to use the WiFi adapter, and (2) the 6.5 kernel installed with Ubuntu 23.10 does not load that driver by default! Now I'm looking for the simplest path to using that firmware.

I tried building the kernel from scratch following the instructions at here; I modified the first line to clone the Linux 6.5 kernel, but otherwise built according to the instructions there. After exhausting a separate path of instructions to get the makefile to build, I have not been able to build the kernel there. I'm basically looking for the simplest way to get the ath12k drivers in my OS so I can remove the 15 m ethernet cable from my house. IS there something stupid simple that I'm missing?

Some data if it helps...

So I have a desktop with Ubuntu, and my graphics card is a GeForce GTX 1060. I switched from Ubuntu 20.04 to 22.04 about a week ago, and haven’t had any problems at all - until yesterday. It was then that my computer froze, seemingly randomly.

Nothing was responding for like 10 minutes, so I turned it off by holding down the power button, and then turned it back on again.

Upon booting up though, I noticed that everything was significantly slower. Looking at Additional Drivers revealed that the list of drivers was completely gone, along with any mention of the GPU.

I tried updating the drivers with ubuntu-drivers autoinstall, but to no avail - it just says that all the drivers are up-to-date.

Running sudo lshw -C display didn’t seem to detect the nvidia card either. Instead it listed a UHD Graphics 630, which I guess is the... backup graphics card or something?

At this point I’m not sure what to do. Has anyone here dealt with this before? What might cause Ubuntu to forget about the graphics card, and is there any way to fix it?

UPDATE:

I just booted from a live usb with Ubuntu 20.04, which seemed to recognize the graphics card just fine. So it's not a hardware issue, thankfully. I guess it's something specific to my current installation?

I'd really rather not reinstall the OS though, if I have any choice. Also I have no idea if the bug is version-specific, so it's possible I might encounter it again in 20.04 anyway. Which would mean I'd reinstalled for nothing.

UPDATE 2:

Just booted again from the same live usb as before, and this time the problem did not go away. No nvidia card to be found, and no drivers in Additional Drivers. The only other issue I encountered was that the disc-check at the beginning ended with "found 23 errors on your system", before proceeding to the installation menu. Maybe it's correlated?

But anyway, now I'm back to having exactly 0 solutions. I have no idea how to proceed. Any more help would be greatly appreciated.

Can anyone can tell me what is really happening here? Ubuntu boot has been stuck here for one hour. I upgraded Ubuntu from 18.04 to 20.04, and after upgrading Ubuntu got stuck at a black screen with boot messages. Nothing is happening here. What should I do?

This is the first time I booted after up upgrading.

I do not use an Nvidia driver.

I am stuck on this screen when I boot up Ubuntu.

/dev/sda3: clean, 327541/183115776 files, 18062476/732434688 blocks 
_

Info about my computer:

• Intel CPU Core i7-6700K
• Intel HD Graphics 530
  • GPU: Skylake GT2
  • Subvendor: ASRock
  • Multi-GPU is disabled

I've looked online here, and used methods, like using nomodeset when booting up, but that didn't work either. I've also tried something like removing nvidia using the sudo command, but I don't even know because I don't use an Nvidia driver.

I had to run fsck on the main partition and this led me to not have grub anymore. So I tried to reinstall it following the instructions here. The first solution got me the error "mount: mount point /mnt/boot/efi does not exist". I tried also with Boot Repair but it didn't show me the "Recommended repair" button. Please help me.

I am getting a kernel panic Ubuntu 20.04 when trying to shutdown. Reboot somehow goes through. I tried to shut down using init 0 or from the GUI yielding the same result. image link: https://i.redd.it/a2w2rlci1mw41.jpg

I'm trying to set up a VPN on Ubuntu 18.04.3. Following the suggestions on this question, I added the following lines to the end of the .ovpn file:

script-security 2
up /etc/openvpn/update-resolv-conf
down /etc/openvpn/update-resolv-conf

I also ran

sudo rm -i /etc/resolv.conf

sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf

to fix /etc/resolv.conf.

Then I created the VPN under VPN Settings -> Add VPN -> Open from File, and used the .ovpn file.

However, when I turn the VPN on, the computer still uses the local DNS server, rather than that of the VPN.

Here are the results of various diagnostics, with the VPN on and off:

dnsleak.com shows the VPN's DNS server, and host -v www.ebay.com gets its data from 10.34.48.1.

Two interesting output lines from the initialization of the VPN from the terminal are:

/etc/openvpn/update-resolv-conf tun0 1500 1553 10.34.48.8 255.255.252.0 init
dhcp-option DNS 10.34.48.1

It looks like maybe the openvpn command is changing the dhcp-option, but the network manager is not.

I am a new one to Ubuntu16.04LTS. After I install anaconda on ubuntu16.04, the problem "Anaconda Navigator cannot be run with root user privileges" occurs. (PS: I log in Ubuntu as the root user) What should i do to open the navigator? Looking for your help, thx.

My Ubuntu 14.04 was working fine, but suddenly it got shut down and now it is not getting past the purple boot screen. I tried using Recovery mode, but I get presented with some error logs. What could be wrong in this case?

I also tried doing fsck, but I got that fsck is not installed. Unfortunately i do not backups of many important files on the system. I would like to know if there is any option of recovery.

I configure a private docker registry server to store images. I am Ubuntu 18.04.

I have a problem in the interaction between the nginx container and the registry container.

Very slow speed when running a push image. The problem looks like this.

The push refers to a repository [192.168.3.131:6080/my-ubuntu]

If you open the port from the container registry, docker push works well. I guess the problem is in my settings in nginx, but maybe not.

For testing, I made a project https://bitbucket.org/mrvstas/registry-docker

Can anyone come across a similar? What to do with nginx? What to do with docker registry?

I just installed Ubuntu 16.04 on my new desktop, Dell Alienware Aurora R7, with i7-8700K, 32GB RAM, SSD(SM961 NVMe SSD) and 1080TI.

So far everything works OK except I get a kernel panic when I try to shutdown (reboot works OK).

How can I avoid this?

I fresh installed Ubuntu 16.04 alongside Windows 10 that was preinstalled on the PC and then updated the Nvidia graphics drivers. Somehow I can't shutdown, and get IRQ interruptions. Ubuntu gets stuck at a black screen and then I can do nothing except hold down the power button to manually shutdown the computer.

---\[ end Kernel panic - not syncing: Fatal exception in interrupt

When I boot Ubuntu, the screen will flash black before rendering the desktop.

I tried to update grub: ACHI=force which didn't help. I suspect it is an issue with some drivers, but I'm not sure what causes it. I tried to determine which GPU is active, and I tested:

glxinfo|egrep "OpenGL vendor|OpenGL renderer*"
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce GTX 1080/PCIe/SSE2

Nvidia X Server Settings application shows that it is using Nvidia driver version 384.90.

I have a dual boot Ubuntu and Windows 10 laptop.
I ran general updates and now my Ubuntu won't boot.
I ran it in Recovery mode and it still freezes in the same place.

Last night I shut down my computer which is running Ubuntu 16.04 normally and went to bed. This morning I tried to boot Ubuntu and I encountered this boot screen:

Ubuntu won't boot and recovery mode encounters a kernel panic. It says /sbin/init: No such a file or directory. I tried this solution (that I found on multiples sites). It says init is already installed. I also tried Boot-Repair and after that I am facing the same problem as before. It seems files are OK and software is up-to-date.

After a few months of not using my Ubuntu laptop, I decided to use it again. For a few days it was extremely slow, with applications randomly freezing every few minutes, simple commands like ls are taking 6-7 seconds, and not being able to locate any packages using sudo apt-get install.

Today the laptop finally decided to not boot and a block of messages is being produced on tty1. I can log onto tty1 and some commands such as cd seem to be working, but this block of messages is just output over and over again every few seconds.

Since I'm on my phone right now and for some reason I can't seem to attach a photo, I'll write out the messages continuously being output.

ata1.00 exception Emask 0x0 SAct 0x20 SErr action 0x0
ata1.00 irq_stat 0x40000008
ata1.00 failed command: READ FPDMA QUEUED
status {DRDY ERR}
error {UNC}
blk_update_request : I/O error, dev sda, sector 900338152

Some numbers do change as the block of message is repeated, but this seems to be the gist of it. If possible I would like to retain the files on the laptop.

I want to install my Evermore Integrate Office 2007 from my cd. Followed the instructions exactly, but hit different problems. Previously I installed it like that on an Acer Aspire One Netbook.

Linux Installation: Method One: Log on as root and insert the CD installation disk in the CD or DVD ROM drive, run from the EIOffice CD and the EIOffice Install Wizard will begin. Follow the On-Screen install procedure.

Click on setup and I get this error;

Invalid url: '/media/chris/EIO2007/Linux/setup' given, exiting
No ':' in the uri

Method Two: Log on as root and Insert the CD installation disk in the CD or DVD ROM drive. Run the terminal window and input "cd /mnt/cdrom/Linux", press Enter and then input "./setup", the EIOffice Install Wizard will begin. Follow the On-Screen install procedure.

Sudo'd into root. In my case ~#: cd /media/chris/EIO2007/Linux. Command "setup" gets error command not found, ./setup gets error Permission denied.

Tried cd /media/chris/EIO2007 then cp /media/chris/EIO2007/Linux /usr/EIO2007 gets cp: omitting directory /media/chris/EIO207/Linux' (read-only disc?)

chmod 1777 not working as expected since it is a read-only disc.

I can read all the files in command line after cd /media/chris/EIO2007/Linux and ls -l as I see them in the File Manager, so I don't understand the error in the first method.

Thought of sudo apt install, but there is no identifiable file name. The /Linux/assocaiate (sic) folder has three directories; Fedora, Impi and Suse. Oh yes, there is a "dispose.jar" file but I do not understand/fear to try it without at least some knowledge of it.

Wit's end. Any ideas welcome, thanks.

I am using "Ubuntu Server 14.04.1 LTS" and I'm having a problem reading if a file on a NTFS samba share is marked in windows as "hidden". Please help me find either the package I need to install to get this, or the correct command to read the attributes (including if it's marked Hidden in ntfs (windows))

(Please note, this has nothing to do with if the filename starts with a dot.)

I have Ubuntu 14.04.2 with both Nvidia GeForce 860m as well as Intel.

I want to install CUDA. I downloaded cuda-repo-ubuntu1404_7.0-28_amd64.deb from developer.nvidia.com/cuda-downloads
I followed this link and did:

sudo apt-get install build-essential  
sudo dpkg -i cuda-repo-ubuntu1404_7.0-28_amd64.deb
sudo apt-get update  
sudo apt-get install cuda  
echo "export PATH=/usr/local/cuda/bin/:\$PATH; export LD_LIBRARY_PATH=/usr/local/cuda/lib64/:\$LD_LIBRARY_PATH; " >>~/.bashrc && source ~/.bashrc  

Then when I reboot the computer, the laptop gets stuck with the ubuntu logo just before login. Why is that? I tried to understand why that happens, and got confused. Do I need to install Nvidia drivers before doing so, or does CUDA install kit already include it?

I tried to install the drivers using ppa-xorg edgers following this link. I managed to install the drivers, and reboot. and then tried to install CUDA again the same way and got the same problem. Is it because I have hybrid graphics, both Intel and Nvidia? If so, can I fix it? Each time it happens I end up reinstalling Ubuntu.

I only care about getting CUDA working.

Normally the boot screen should says 'ubuntu' with five orange dots below it, but in my PC, they suddenly turn into this:

• Glitched boot screen image
• Glitched boot screen 8 seconds video

Here is my hardware:

• Intel Core 2 Quad Q9550
• HIS HD 4670 IceQ
• Asus P5Q

How can I fix this?

I have a very beginner question. I would like to create a shortcut to a directory that is global so that when I do something like

cd $dir

It will take me to the specified directory. Or if I am prompted to specify a download path in some program I can just input $dir into the field.

Thanks

I'm new to Linux. I want to enable a nice splash screen on the GRUB boot menu. I have Ubuntu 11.04, running on an Nvidia graphics card.

I want to set a background image when GRUB shows a list of available OSs. I've changed the color through grub.cfg in /boot/grub, but I can't set an image as background in the list.
