I am running Ubuntu 25.10 and my Software Updater app is configured for "Notify me of a new Ubuntu version: For any new version" but 26.04 is not yet showing up. When will it be available for the Software Updater?

Please note I am asking about updating from 25.10 to 26.04 and the questions in the the link you say answers my question are about updating LTS versions, ie from 24.04 to 26.04. I see a difference there but if you want to remove my question go ahead.

i did some basic tweak for supressing the Wayland Display, but could not set to x11.

Can someone post how i can disable Wayland and continue on X11 i haev some apps that dont support Wayland.

I’m making use of an old (2012) MacBook Pro. Great little machine, but Apple is no longer supporting my OS. I’ve never used Linux software to my knowledge and am apprehensive on which OS will best suit my needs. My biggest concern is the learning curve. Is there an OS that is most similar to a version of MacOS so that I can soften the shift? Furthermore, I do a boatload of work using DSP (Digital Sound Processing) software, specifically SigmaStudio, which is a “windows only” software. I realize that my Mac wouldn’t run it anyway, but I’m curious if anyone knows of a Linux compatible software that will connect and tune the ADAU14xx and ADAU17xx DSP chipsets, or any other mainstream chipsets on the market that are in this general realm.

Thanks for the help.

I'm trying to install Ubuntu 24.04 LTS alongside Windows 11 (dual boot) on a brand new HP EliteBook x360 1030 G8, and the installation consistently fails at the partitioning step.

Hardware:

- HP EliteBook x360 1030 G8

- Samsung MZVLW256HEHP-000L7 NVMe SSD (256GB)

- Windows 11 pre-installed

Disk layout (from sudo parted /dev/nvme0n1 print):

Number  Start   End     Size    File system  Name
1       1049kB  211MB   210MB   fat32        EFI system partition  (boot, esp)
2       211MB   228MB   16.8MB               Microsoft reserved partition (msftres)
3       228MB   42.0GB  41.8GB  ntfs         Basic data partition (msftdata, no_automount)
4       255GB   256GB   826MB   ntfs         (hidden, diag, no_automount)

[213GB free space between partition 3 and 4]

What I did:

• I first tried the automatic "Install Ubuntu alongside Windows" option, which failed

• Then I tryed to select "Something else" for manual partitioning, created a new ext4 partition (nvme0n1p5, ~212GB) in the free space, mounted it on `/`, set the bootloader to `/dev/nvme0n1`, then clicked "Install Now".

Error:

In both cases :

OSError: could not get path to dev from kname: nvme0n1p5 could not get path to dev from kname: nvme0n1p5

What I already tried:

- Ubuntu 26.04 and 24.04 — same error on both

- Recreating the USB drive with Balena Etcher

- Disabling wifi during installation

- Minimal installation without updates or third-party drivers

- Checked Secure Boot — already disabled

- Checked Intel VMD in BIOS — "Configure Storage Controller for VMD" is unchecked

- BIOS is up to date according to HP diagnostic tool

Has anyone any idea ?

Thank you

I've just installed Ubuntu 26.04 on my PC. I am using the built in Gnome Remote Desktop, however it is a bit unstable, as the connection will be working for a few hours and then it crashes so I cannot connect again. The only fix I have been able to get working is to SSH into the machine and reboot.

I have tried the following commands via SSH as well, but none of them seem to fix the problem.

systemctl --user restart gnome-remote-desktop
pkill -f gnome-remote-desktop
killall -1 gnome-shell
sudo ss -lntp | grep 3389
sudo kill -9 \<PID\>

I have relatively little experience with Linux, so I'm unsure where to find logs or how to debug this problem.

We are running a bunch of containers for a cyber security teaching environment, where students can execute arbitrary commands (unprivileged).

Our system (Ubuntu 24.04.4 LTS) is affected by the recently-published "Copy Fail" vulnerability (CVE-2026-31431).

Unfortunately, updating did not produce any new kernel packages, and we are still stuck with 6.8.0-110:

# uname -a
Linux teaching-host 6.8.0-110-generic #110-Ubuntu SMP PREEMPT_DYNAMIC Thu Mar 19 15:09:20 UTC 2026 x86_64 x86_64 x86_64 GNU/Linux

PoC exploit:

$ cat exploit.py | python3 && su
# id
uid=0(root) gid=1000(user) groups=1000(user),4(adm),24(cdrom),27(sudo),30(dip),46(plugdev),101(lxd),988(docker)

How can we harden our system until an official patch package becomes available?

The below image is what I encountered. Now I can connect to xrdp, and can log in as well, however I cannot do anything, including mouse click or tapping the super button.

What I did:

xrdp worked properly until I started to configure the Nvidia GPU for xrdp. When I found that it couldn't work, I tried to uninstall xrdp and reinstall it, but nothing changed.

sudo systemctl stop xrdp xrdp-sesman
sudo systemctl disable xrdp xrdp-sesman
sudo apt purge -y xrdp xorgxrdp libxrdpdev libxrdp2
sudo rm -rf /etc/xrdp /var/log/xrdp* /run/xrdp*
sudo rm -rf /home/*/.xsession /home/*/.Xauthority
sudo rm -rf ~/.xorg*
sudo deluser xrdp ssl-cert 2>/dev/null
sudo apt autoremove -y
sudo apt clean

sudo apt install xrdp
sudo systemctl enable xrdp
sudo adduser xrdp ssl-cert
echo gnome-session > ~/.xsession
sudo systemctl restart xrdp

I am doing some stability testing between 2 STA, and I have encountered a weird latency behavior.

This is my environment:

• PC1: Ubuntu 22.04 mainline 5.15.0-130-generic + compex WLE900VX(wifi 5)
• PC2: Ubuntu 22.04 mainline 5.15.0-130-generic + compex WLE900VX(wifi 5)
• AP: TP-link AX3000
• Driver: ath10k_pci 5.15.0-130-generic SMP mod_unload modversions

The connection flow:

PC2 (Wireless) ---> AP ---> PC1 (Wireless)

When I try to ping PC1 from PC2 within the same LAN, the latency is unusually high and unstable, but if I ping the 8.8.8.8 from PC2, the latency seem like fine and stable.

Has anyone encountered the problem like this?

So when I try to connect to any internet inside the network manager I only have the options network settings and network connections which neither of them let me connect to any internet. I have tried to look at other forms to see if I could figure it out but I have not been able to. When I connect an Ethernet cable up nothing happens and I have tried to connect it to my phone so whatever the solution is it can’t use anything that has to be online so I have no clue what I am supposed to do. I have also made sure IPv4 and IPv6 were both set to automatic. I am running Linux mint 22.3 cinnamon.

I have recently returned to Linux after a long hiatus, currently using Ubuntu 24.04.4LTS.

I have a large collection of images that I would like to sort and arrange but I am having problems with thumbnails showing up in the file manager (Gnome Files 46.4). Some photos do generate a thumbnail, but most simply give me a purple, generic icon. To make it more difficult for me to understand, some of my folders show thumbnails for all photos in that folder, but then a sub-folder doesn't display thumbnails at all. This problem seems to be irrespective of image file type.

When I open an image in the image viewer (Gnome Image Viewer 45.3 or Eye of Gnome 47.0), the image displays properly, but the thumbnails of the other images in the folder do not display at the bottom of the window.

Without thumbnails displaying consistently in the file manager, it is impossible for me to manage my image files. Is there a solution, or perhaps a better file manager?

No LTS by Ubuntu-Mate, no hesitation, please only indicate the current state. I would prefer it would be going on.

I have an ASUS TUF Gaming F16 with an RGB backlit keyboard. How can I configure the COLOR of the keyboard and any effects, not just the brightness? I hate the default color changing effect and I just want it solid green.

GSK_renderer=cairo significantly reduces the memory usage of GTK4 apps.

I am thinking about applying it to some of my low-end computers by adding it to /etc/environment. However, I don't want to turn off system-wide hardware acceleration.

By any chance, does this environment variable stop system-wide hardware acceleration, or is it only for GTK4 apps?

The official canon site reports the os as incompatible. How can I get my printer to work with Ubuntu?

How to do this for latest LTS 26.04 and the previous LTS 24.04?

Today I upgraded to Kubuntu 26.04.

Moving my mouse coursor onto my second monitor using Wayland (Plasma) will permanently freeze the video output. This also happens in the login screen. I am able to circumvent it by using awesome-wm, but strongly prefer plasma. And it only occures when moving the mouse coursor there, having applications open and using keyboard shortcuts does not trigger it. Disabling the internal screen and just using the external one also does not help.

System is still running, as I am able to ssh in and reboot it.

/var/crash/ is empty prime-select is on nvidia. I should not that I can switch to intel, but that also disables the HDMI port, so the problem cannot be replicated then.

Adding KWIN_FORCE_SW_CURSOR=1 to /etc/environment does not help.

In the recommendations of best practices to upgrade an Ubuntu distribution (and in a previous similar post), it is recommended to:

Disable all non-Ubuntu (unoficial) deb sources, including disabling PPAs. Uninstall the deb packages that those sources provided. Return your deb packages to as close to stock condition as possible.

I know sources can be disabled in the Software and Updates application, by using add-apt-repository -r, or by adding Enabled: no to the .sources files. But how can I also uninstall the deb packages that were installed from those sources?

I have seen ppa-purge being mentioned, but it did not work properly for me. To give an example for josm that did not seem to do anything:

❯ sudo ppa-purge -s josm.openstreetmap.de ppa:apt/dists

The output of apt policy still includes:

and the contents of /etc/apt/sources.list.d/josm.sources remain (i.e., they do not include Enabled: no):

Is there any other simple way of removing deb packages that were installed from non-Ubuntu (unofficial) sources?

I'm from India, currently running Ubuntu 24.04.4 LTS. I am excited to upgrade to the newly released 26.04 LTS. However, even today's morning (Apr 25), my software updater couldn't find a newer version to upgrade to. Articles like (https://linuxconfig.org/upgrade-ubuntu-24-04-to-26-04) and (https://linuxize.com/post/how-to-upgrade-to-ubuntu-26-04/) suggest a manual upgrade via the terminal, first upgrading to a non-LTS version (25.10). I am not willing to wait till 26.04.1 LTS release.

How do I upgrade? Please help!

Not sure if this or a mathematica-focused forum is the right place for this, but I suspect my issue is something with my ubuntu setup, so I am hoping someone here will have some ideas.

I am trying to install Mathematica from the official installer Wolfram_14.3.0_LIN_Bndl.sh, but it's being strangely annoying.

When I try running it, with any of ./Wolfram_14.3.0_LIN_Bndl.sh, sudo ./Wolfram_14.3.0_LIN_Bndl.sh, bash Wolfram_14.3.0_LIN_Bndl.sh or sudo bash Wolfram_14.3.0_LIN_Bndl.sh , I receive output of the form

Wolfram Mathematica 14.3.0 for LINUX Installer Archive

Verifying archive integrity. 
Error in MD5 checksums: 7b75ed1e8117f0a81eea3b41358b9e28 is different from b78ec7c79750834b95d15731c9903fa4

However, the wrong checksum is computed each time, e.g. the 7b75ed1e8117f0a81eea3b41358b9e28 will become f393c094e26d8506c0cca1bc8addb413 or something else each time I run it.

I downloaded the script from wolfram's website, so I know it is the correct/official one. I do not have any good guesses for why the wrong checksum is being computed or why it is different every time. I tried bypassing this check by manually editing the relevant function in the shell script, but then the install fails at the next step with output

Wolfram Mathematica 14.3.0 for LINUX Installer Archive

Verifying archive integrity. 
Extracting installer. ........Extraction failed. No space left on .625963
.Removing temporary files.

I am also confused by this. It seems some tar command is failing under the hood, but I do not know why. It certainly is not because of a lack of space; I have hundreds of gigabytes free, and while Mathematica is pretty big, it's not that big.

At this point, I am very confused about what is causing these issues, so I thought I would turn to the internet for help. Does anyone here have any suggestions?

Some extra considerations

• I know the installation script itself is fine. I pulled out an old laptop and tried running it on there, and it worked with no issue. If it matters, my current computer is running Ubuntu 25.10, but the old one is running 25.04.

• The md5sum function on my (current) laptop also appears to being working correctly. I tested this via echo -n "The quick brown fox jumps over the lazy dog" | md5sum and comparing the output to this example given on Wikipedia.

• If it matters, my computer has two physical SSDs in it. One is basically a huge storage partition and is where the install script is downloaded. The other has my Linux partition (as well as a separate Windows partition for emergencies). I doubt this matters for anything, but figured I'd mention it just in case.

Let me know if I can provide any more information about my setup/computer, if I should provide any snippets of the installation shell script, or if I can share anything else that might be helpful. Also let me know if there is a better place to ask for help with this. Thanks.

I have a question about RPI4 (4G Ram) + Ubuntu 24 + Chromium. There was a problem with hardware video decoding. It is blocked by default on all APT packages for Ubuntu including Chromium. So I made some investigation and found a workaround here I succesfully unblocked the HD acceleration but the video is still slowed down.

I am at the end of my ability to fix it so I would like to find some help with it here. Do I need to do something to fix the slow videos? This is the message from dev tools->more tools->media

Cannot select DecryptingVideoDecoder for video decoding Cannot select V4L2VideoDecoder for video decoding

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...

I apologize immediately for my English

After buying a new notebook, Acer aspire A514-52-59EQ, with pre-installed Windows 10 home I wanted to go back to my dear old Ubuntu, in the new version 20.04LTS, specific that I have already tried with Ubuntu18.04 LTS, 19.10 and other various distributions Linux.

I have obviously disabled secure boot and quick start of windows.

During the installation, however, the warning of incompatibility with intel RST appears.Following the guide to which the warning refers, a request is made to change the SATA mode in AHCI from the Uefi Bios.

The problem is that inside the BIOS my SATA device is in "optane whitout raid" mode, but in the itntel optane app this is disable, and I cannot modify it in any way.

My storage controller is Intel SATA / Pcle RST premium controller chipset. Intel told me to uninstall it quietly, although I was doubtful that it managed the disk, I ignorantly trusted, I did it and the only thing that caused it was the inability to access the disk resulting in the necessary restore.

Instead, by contacting the Acer, they was told me that it is possible to create a Live USB in order to overcome the problem, but that since it was not their responsibility, we could not say more.

Can someone help me?

Thank you

Anyone able to help with Steam Rom Manager

Application is throwing this error on Ubuntu 19.10:

I installed Ubuntu 18.04 and then while installing Virtualbox i get the 'i386' error message after I did:

I found several answers on Askubuntu for the 'i386' message but I don't know how to apply this to my situation

When I rebooted my Ubuntu 14.04 it gave the following error. I tried ls and it still threw the error below. Could some one give me an exact answer on how to solve this issue? I need this help a bit urgently.

What is the best method I can use which will help me to at least get data from my /home folder and then I can format this disk if it is really failing?

Here is the error

grub rescue> ls (hd0, msdos1)
(hd0, msdos1) : Filesystem is unknown.
error: failure reading sector 0x802 from 'hd0'.
grub rescue>

Please help me correctly to solve this issue. I just need data from my /home folder once that is done I can format the disk and reinstall.

I'm running Ubuntu 14.04 and set up my system using LVM with full disk encryption. Then I installed uswsusp and the loading failed. I searched the web and found that this is because my swap partition is encrypted. But all solutions I found on the web deal with the case where only the swap partition is encrypted (not using LVM to encrypt the whole disk). Is there any way to enable hibernate on a fully-encrypted disk?

I have a netbook that I want to install Ubuntu onto. I do have a good Mac computer that I can make a bootable USB drive from, but I'm confused on how to go about making it.

I have a working MacBook Pro and a crashed Windows 7 PC. I was running Ubuntu on my PC, but after a recurrent issue now I can't boot either OS. I would like to install only Ubuntu on my PC and will make Windows 7 history for good, but I am a bit puzzled by the instructions for creating a bootable USB options on the website.

If I create a bootable USB on my Mac following the instructions for OS X, would it boot in a PC?

For a given hardware configuration, how do I find out if Ubuntu will run on it? What considerations should I take into account when choosing an Ubuntu version and flavour such as:

• Xubuntu with a lighter desktop than the usual Gnome and Unity
• Lubuntu with the even lighter LXDE desktop

Obviously Ubuntu does not run on some processor architectures. So how do I go about choosing the right version and derivate. How can I find out the minmal system requirements?

I am running an HP pavilion dv6000 dual boot win7 and Ubuntu 12.04. (well, up until today). After a reboot, the boot process drops to the BusyBox shell and I end up at the prompt:

BusyBox v1.18.5 (Ubuntu 1:1.18.5-1ubuntu4) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs)

I've been researching others who have had this same problem, but haven't been able to find any of those solutions to work for me.

I tried the method described here, and after the final command

mount -t ntfs-3g /dev/sda1 /root -o force

it does nothing and gives me another (initramfs) prompt.

I can boot to a live CD (USB) and get to a terminal, but it doesn't seem to do much good, as I can see the /dev/sda1 in the ls command, but it doesn't recognize it when I try to cd to it.

One more question: using the command fdisk -l how can I tell which mount point (sda1/sda2) is my windows partition and which one is Ubuntu?

If you select "USB" and "Mac" on this download page, it gives a series of command line instructions to make a USB key which the MacBook will boot into Ubuntu from.

I've followed them to the letter two or three times on different USB keys, and it doesn't work. There's a very great deal of technical discussion about EFI etc. but this set of instructions seems to suggest it should just work, but it doesn't.

Help? I'm increasingly unhappy with the more locked-down approach Apple is taking, and I'd quite like to start using Linux with a view to transitioning over to using it as my main operating system, but booting from the CD takes forever, runs slowly and I'm really hoping to get it moving off USB.

Can anybody help me?
