In Xubuntu 25.10 I need numeric keypad to always enter numbers and I want to turn numlock always off. Is this possible? In Keyboard section of Settings in Ubuntu there's an option for this, but I couldn't find it in Xubuntu. Do I need to install anything?
I'm following the guide to install Home Assistant OS on a laptop. To do this I need to use the Try Ubuntu on a live USB. The Ubuntu version I'm using is 24.04.3.
To complete the install, I need to flash an image of Home Assistant to the internal drive. The problem is the internal drive is not showing up. lsblk and sudo fdisk -l both aren't showing the drive but are showing the live USB.
Any suggestions?
I have a laptop running Ubuntu 24.04.2 LTS.
I am unable to get the network running, and in the settings menu the option for wireless and wired connections is missing. Additionally, I cannot use my mouse and the system no longer detects my Bluetooth card. Yesterday, everything worked fine, and I did not make any changes to the system since then.
What should I do?
I use gnome.
Should I try another USB slot for my wireless keyboard and mouse set?
This is my Ubuntu version.
Ubuntu 24.04.3 LTS.
I haven't made any changes in the last few days except for an update.
It is a very annoying problem.
Tell me if you need more information from me.
Thank you.
And love from Israel....
I just built a new PC and I'm trying to mount two internal hard drives from my old desktop so that I can use the data on them. When I look at it in Windows, everything seems perfectly in order:
Windows disk manager screenshot
Those two drives, G: and F:, are the ones I want to bring over. They're functioning perfectly fine, and I can access all the files on them through Windows. All seems well.
So I boot up Ubuntu 24.04.3 and run sudo parted -l and get this as the result:

/dev/nvme0n1 is my Linux OS drive, and /dev/sdc is my Windows OS drive. Do you notice in /dev/sda and /dev/sdb how there is nothing listed under the "File system"? Windows said these were NTFS partitions, and /dev/sdc correctly displays as such, but those two other drives do not for whatever reason.
I figured maybe they're still registered as NTFS internally and for whatever reason it just isn't showing up. So, I put in sudo mount -t ntfs /dev/sda2 /mnt/drive_1 and this was what I got back:
NTFS signature is missing.
Failed to mount '/dev/sda2': Invalid argument
The device '/dev/sda2' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?
I have no idea what's going on with these drives at this point. Windows is telling me there's an NTFS partition on both drives, and Linux is saying that the partition isn't NTFS. Or at least, Linux doesn't recognize it as NTFS for whatever reason. I only just started using Linux a week ago, so I have no clue what the source of the miscommunication between Windows and Linux is.
Does anyone have some insight on what to do about this? Worst comes to worst, I have both drives backed up externally and I'll just spend a few hours putting files and programs back after I clear the partitions and mount them from scratch. But if I can, I'd rather just mount them as-is without losing the data from reformatting.
EDIT: I have disabled hibernation/fast startup in Windows, but I still get the same results in Linux. I also don't have BitLocker encryption (or any other encryption) enabled.
Running Ubuntu 22.04.5 LTS and my RAID is software based with UEFI boot.
I think I have a two-part problem:
History:
I have had a RAID 5 array with 4 drives working fine for the last few years. When the server restarts it hasn't hung up and no issues. I recently needed to grow the array by adding a 5th drive, but had problems from the get go because once I installed the new device the server hung up at post and never acted like it recognized the new device. I finally partitioned on my Windows PC, and finally after an hour of messing around got the Ubuntu server to recognize the new drive and I was able to follow the below steps to grow the array.
Steps I followed:
0. Here is what lsblk outputted before adding the new drive
sda 8:0 1 7.3T 0 disk
└─md0 9:0 0 21.8T 0 raid5 /mnt/plex

mdadm --add /dev/md0 /dev/sdg
mdadm --grow /dev/md0 --raid-devices=5
sudo resize2fs /dev/md0
Once I did this everything seemed to be working fine, and I had my additional space. Not sure if I missed a superblock step or that is done during the grow process.
Fast forward a week and now that I restarted my server, it gets hung up on the post screen and I can't get my md0 RAID reassembled.
adam@tron:~$ sudo mdadm --assemble /dev/md0 /dev/sda /dev/sdb /dev/sdc /dev/sdd /dev/sdg
mdadm: /dev/sda is busy - skipping
mdadm: /dev/sdb is busy - skipping
mdadm: /dev/sdc is busy - skipping
mdadm: /dev/sdd is busy - skipping
mdadm: cannot open device /dev/sdg: No such file or directory
mdadm: /dev/sdg has no superblock - assembly aborted
I'll post my current fstab file below as well, as I'm not sure if I'm not able to properly work on getting /dev/sdg added back into the array until I can get my server to recognize it.
I know there is data on the new device so I'm trying to keep from zeroing the superblock and starting all over.

so it has been a hot minute since I've run Ubuntu Linux, probably not since 12.04. I have a desktop windows machine I built around 2015. All top shelf components and it is still a rock solid machine. Unfortunately it is stuck on Windows 10 Pro due to the lack of support for Win 11 due to my my mobo not having tpm 2.0.
Here is a link to my build for reference - https://pcpartpicker.com/b/BLRG3C
I appreciate any insight.
Ubuntu 22.04 Communication with installed printer hp1010 has interrupted.I changed the usb cable with no results.I can take the test page just by pressing the green button . Any help would be appreciated!
Hello I recently installed Linux on my computer, and under Windows I had Wi-Fi thanks to an AX900 Wi-Fi Key (link) Unfortunately, it's only compatible with Windows.
Do you know of any unofficial drivers that would allow it to work under Linux?
Thanks in advance!
I have a new Ubuntu installation on my system. I need a driver for using a Epson Stylus TX121 Printer Scanner. Where and how can I download the driver?
I'm endeavoring to remove Snap completely from my Ubuntu 22.04 installation and have got stuck while trying to remove snap-store. Now, whenever I try to execute the command:
sudo snap remove --purge snap-store
I get this error:
error: snap "snap-store" has "remove-snap" change in progress
The thread What does 'snap "opera" has "remove-snap" change in progress' mean and how do I stop it? does not help me; the snap changes command does not reveal any ongoing snap processes that can be terminated.
BACKGROUND DETAILS:
I followed the instructions at https://ubuntuhandbook.org/index.php/2022/04/remove-snap-block-ubuntu-2204/ up until the command sudo snap remove --purge snap-store. When I ran this command, the process got stuck. After 10 minutes, I tried to exit the process using Control+C, after trying a couple of times and waiting a few minutes, I closed the terminal window, knowing it would kill the process. Now when I run sudo snap remove --purge snap-store , I repeatedly get the error message above. I've tried a full reboot: no difference.
I've now used sudo snap remove --purge... to remove all packages for which it works. These items are still shown on the system when I run snap list :

I lost my printer access during last update. Around the beginning of Dec. 2025, my Ubuntu running on an 11 year old Lenovo H535 64 Bit machine (Type 10117) was updated to version 22.04.5 LTS. In the process, my two printers, a Canon LBP6230DW and a Brother HL-L2360DW, were replaced by a "Generic" printer in the printer list, but it does not work.
During the last week I tried to reload the drivers without any success. I tried Gutenprint, can print a test page, but it can't locate the needed files. I cannot print from either Firefox or LibreOffice.
Is it time to buy a new computer, or would newer printers help? What B/W Laser printer might work?
Thank you. I think problem will be solved by editing the 4 lines in /etc/cups/cupsd.conf. I have asked my techie son to advise me how to edit this file, by commenting out the four "unknown" lines with #. Thanks you again. WCarlMayer
deja-dup will not backup to my external FAT formatted hard-drive.
I have tried to change the permissions so that I am the owner with
sudo chown -R $USER:$USER /mnt/usb-Seagate_Backup+\_BL_NA751YCT-0:0-part1
but get the response
chown: changing ownership of '/mnt/usb-Seagate_Backup+\_BL_NA751YCT-0:0-part1': Operation not permitted
Please help ! Ubuntu version cat /etc/os-release PRETTY_NAME="Ubuntu 24.04.3 LTS"
A suggestion to use ext4 formatted hard drive instead of FAT . I have tried it but have exactly the same problem with permissions.
Can you write on it ? No , "Error while copying " "the folder be copied because you do not have permission" Error message given by deja-dup "Error creating directory /mnt/usb-Seagate_Backup+_BL_NA751YCT-0:0-part1/simon-peter-gough-ThinkPad-T14-Gen-1: Permission denied"
Suggestion by Rizwind: : For windows partitions permissions are set when mounting. But you -will- loose all permissions as set for the files if the backup is not tar'd. " I have tried it but have exactly the same problem with permissions." no you don't. You need to set the paritions to the use the backup program uses OR add yourself to its group and it will work
Thank you Rizwind. Sorry, I am a beginner. How do I "set the (partitions ?) to the use the backup program uses OR add yourself to its group "
I wonder if I can set the timeout to the boot time LUKS unlocking and let the PC shut down on timeout.
In other words, I want the PC to shut down automatically when I leave it without typing the password 1min.
This is particularly useful for laptops. Some computers turn on by shock or some other event. Without a timeout, the PC will wait for the password until the battery is fully discharged.
Screenshot of the disk unlocking screen:
Thanks to @user68186, my question is solved. The answer is marked accepted.
The unlocking of the LUKS disk at boot time is done in the initramfs. That answer adds a script and links it from the /etc/crypttab.
I'm trying to install "yfinance" on Ubuntu 24.04. Everyone on the web says to use "pip" to install, but Ubuntu gives a long message saying that's not a good idea, to use the equivalent of "apt install python3-xyz" instead.
That much is ok, but running
sudo apt-get -y install python3-yfinance

AlsaMixer has to be adjusted to make sure the audio levels are set to max or else the volume in Ubuntu is extremely low. I've followed the man page directions and other threads online, but I cannot get AlsaMixer to persist the configuration between reboots.
Is this a known issue with AlsaMixer? I've tried saving a configuration file in my home director under the correct path, I've run AlsaMixer commands using sudo to write files out to /etc and I've even used alsactl store. Nothing works.

Since today afternoon, I'm unable to access any of my filesystems. Whenever I try to open any of them I get the following error
So I would like to describe an issue which might have caused this.
I tried to install fingerprint driver for my laptop (DELL Inspiron 5501). I got carried away with many articles finally downloaded a package which literally checks for any available fingerprint drivers. In order to do that a file with .AppImage had to be run. In order to run that Fuse was needed. So I installed fuse and libfuse2. After that this message appears everytime I open a filesystem.

kill <pid>Now I would be able to run the docker container that has a Postgres database.
I'd like it so that I don't have to follow those steps before I can run any Postgres database.
For some reason lsof -i :5432 does not return the process.
Is it standard behaviour for Postgres to be running in the background? Is it safe to stop this process? If yes, how can I stop this process from running automatically in the background?
I have tried the following commands with no success:
sudo systemctl disable postgresql
sudo update-rc.d postgresql disable
Ctrl + Alt + T opens a new terminal window. How do I make a keyboard shortcut open an existing window for an application if one is already open (and open a new one if not)?
The version of my system is ubuntu 20.04 and of wine is wine-5.0 (Ubuntu 5.0-3ubuntu1)

I have 2 Ubuntu machines (1 laptop, 1 desktop). I want to log in to the desktop from the laptop when I am either or the same network or not.
The desktop, as suggested in a few places, seems to have all the correct "sharing" options turned on.
Additionally, I have Remmina (1.4.7) installed.
I know the IP of my desktop (fwiw, I used: showmyipaddress.eu.
On my laptop I also have file sharing, screen sharing and remote login turned on (this is probably overkill).
I also have Remmina installed (currently 1.4.7).
Now I can connect to the desktop using the "local" name:
But when I try to use the same method, but change the local name to the external IP address, I get "unable to connect to the VNC server".
What do I need to do to make this work?
I'm encountering a connection issue to my university WiFi network that I cannot solve: when attempting to connect, I get the following message with dmesg -T :
[ven. oct. 11 12:32:04 2019] wlan0: deauthenticating from X by local choice (Reason: 3=DEAUTH_LEAVING)
This problem has already been pointed out in the forum, but none of the solutions I tried worked:
/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf set wifi.powersave = 2 ).Adding the following lines to /etc/sysctl.conf:
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1
None of these worked.
I have problem with my priter Samsung. I install driver this way:
tar zxvf uld_V1.00.39_01.17.tar.gzsudo ./uld/install.sh
and everything went ok, driver was install.Then I went to settings and add new printer as default printer. When I wanted print test paper there was:
usr/lib/cups/filter/rastertospl not available: No such file or directory
so I copy rastertospl and rastertospl c files in /usr/lib/cups/filter by using this:
cd /usr/lib/cups/filter/
sudo ln -s rastertosplc rastertospl
sudo ln -s rastertospl rastertosplc
but this doesn't help. Now I see:
usr/lib/cups/filter/rastertospl: Too many levels of symbolic links
I try also add ppd file in settings but this doesn't work too.
Does anybody have idea how solve this problem?
I've installed Ubuntu 18.04 LTS alongside Windows 10. I can access the Windows partition and can read the files. But I can't create any files or folders in that partition. All the options for "Cut", "Move to" and "Rename" are greyed out. How can I have write access to the partition from Ubuntu?
The output for df -H command
The contents of fstab file
The output for sudo lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINT,LABEL
My dell inspiron 660s with intel graphics ran Ubuntu 16.04.3 for a year with no issues, and I decided to give 17.10 a try.
After installing 17.10, ubuntu restricted extras, lowlatency kernel, and applying all updates and rebooting, GDM fails to start.
Here are some relevant log entries:

I have a quick question maybe someone could help me with.
I downloaded a few apps and ISO's from source forge today and they seemed to have disappeared. They weren't in the default down load folder or in the Firefox download cache.
So anyway, I started clicking around in my files trying to locate them and I came across a file string that I hadn't seen before. /var/spool/postfix/etc/ssl/certs. And in it, I found all these ssl CA and Root CA certificates (maybe 200 to 300 of them). I can open them and see pub. key.
Algorithm, Signature (huge table of numbers) and a bunch of other info that seems sensitive. I know very little about encryption and secure sockets, so I was wondering if this is a normal place to find such items.
By the way I don’t use local mail service on the machine. So I don't Know why anything would be in there. Thank You. B
After almost a week, I've just about managed to install Ubuntu 12.04.3 LTS alongside Windows 8 on a Dell XPS 14 Ultrabook.
I have created a partition in Windows to store Ubuntu, rebooted from Windows Advanced Start Up options menu to an EFI USB containing Ubuntu. I've installed Ubuntu on my chosen partition with 4GB swap area also set aside.
During the install, I get this error message:
The 'grub-efi-amd64-signed' package failed to install into /target/. Without GRUB boot loader, the installed system will no boot.
After some searching, I read that I should use Boot-Repair, which I've done following the instructions here.
However, after running Boot-Repair and choosing the auto diagnose and repair option, I get a message to,
Please close all your package managers (Software Center, Update Manager, Synaptic, ...) Then try again.
Can someone please help me with what I need to do next as it's driving me mad?
Ubuntu is installed (if i try to reinstall on the same partition, my previous installation is there), it just seems I need to fix this problem.
Please help - Windows 8 is awful but I'm getting very tired of the endless pushing a big rock up a steep hill that installing Ubuntu is.
I have Ubuntu 13.04 and when I want run Vega program by ./Vega
I get this message
An error has occurred. See the log file
/home/engalaabt/.eclipse/1150212041/configuration/1371636662714.log.
so what is the problem and how i can fix it ?
