I am trying to set up remote control for an ARM Parallels VM running Ubuntu 26.04 LTS, from the host Mac Mini M1. I am using Windows App (formerly Microsoft Remote Desktop) ver 11/35 (2947) on Tahoe 26.5 (all current versions as at 20/5/2026).

I am trying to use Gnome Remote Desktop as installed for that version of Ubuntu. I keep getting an error 0x0207 (authentication error) when I try to conect with Windows pp (even though I am using the correct username and password)

Has anyone successfully set up RDP remote access on this version of Ubuntu?

Does Ubuntu 26.04 have a driver in the kernel for Wifi Chipset: MediaTek MT7922?

Application could be launched in 25.10 from the desktop. After upgrade to 26.04 ALL the desktop shortcuts have a red cross and at right click there isn't any allow launch option anymore. The files do exist and where unmodified. Any suggestion for root cause or how to fix ? checking files chmod to +x does not fix it. But all files have x bit set. The dekstop files are in ~/Desktop and when opening the item form the desktop with another application (i.e gedit) the file can be edited.

I'm running Ubuntu 26.04 LTS, 64-bit, Linux 7.0.0-15-generic, gnome version 50.

And using an NVIDIA GeForce RTX 3060.

I downloaded and installed the new Ubuntu, onto a newer computer. Installed Steam, and was met with the message:

"32-bit NVIDIA driver files were not found on your host system. It's best you install them for the best experience."

It then gives some terminal commands.

sudo dpkg --add-architecture i386
sudo apt update
sudo apt install libnvidia-gl-595:i386

Enter the commands in that order and it gives me this response:

I'm a new user to Ubuntu 26.04. I'm using Ubuntu to both serve a data drive to my home network as well as controlling Ubuntu (so I can learn more about it) via remote control from the MacBook. It works very nicely when it's working, but anytime I reboot I must connect a keyboard and mouse to the Ubuntu PC and manually go into System/Remote Desktop and select UNLOCK and enter my password for the system to allow remote connection on the Mac. I should mention I'm using a Mac application now called "Windows App" to initiate that remote connection.

What I really would prefer is to just reboot and be able to connect the remote desktop. The Ubuntu PC already auto logs in, but not the RMD.

I use Ubuntu Desktop 25.10 and want to upgrade to Ubuntu 26.04
I have updated + upgraded my packages multiple times, yet the same error occurrs:

Reading cache
Distribution data outdated 
Please ensure all package updates are installed, and then try again. 
=== Command detached from window (Wed May 20 22:51:41 2026) ===

I have a Ubuntu OS 24.04 LTS and it has a RTL8192EE PCIe wireless network adapter.

When I updated to 26.04 from terminal using sudo do-release-update -d my wireless adapter stopped working, and I have no clue why. I wonder that the drivers from that adapter are updated just for Windows, because when you visit the drivers website (https://www.realtek.com/Download/List?cate_id=672&menu_id=297) it only shows the Windows drivers, not Linux or others.

I tried re-scanning the drivers and making rm to reinstall them, viewing Secure Boot, rfkill bloq, NetworkManager restart.

Is changing the PCIe Adapter an option? Is there other way to solve it?

Starting 25.10 Ubuntu (Gnome) installer could install alongside Windows even with Bitlocker ON, if there is a freespace already.

But today when I installed 26.04, there was no Grub installed in EFI partition (as I checked later through Windows). So there was no way to boot into the Ubuntu, the Bitlocker screen came up. I didn't face this issue with 25.10 when installing alongside Windows with Bitlocker ON.

Should I try Kubuntu 26.04 now? Although they still have Calamares, not Flutter installer, can it work?

This morning I booted my Ubuntu 24.04 and internet connection was gone! Tried some Network restarts and found NetworkManager couldn't start. Some tutorials tell me to get dhclient, but to get that and other drivers and system updates, I need internet connection!

I changed the settings on the systemd file on NM and lowered the amount of seconds to try to get it to stop stopping NM but it's still the same

I'm new and so my knowledge is based on copy and pasting what I find on the internet.

I need my computer. Tried adding wifi manually on the prompt, ancoring from my phone. it's been 5 hours of browsing the Internet for solutions that require me to have internet connection to install the commands.

I am at a complete loss at this point in time. No matter what I do, upgrading to 26.04 was a mistake. Had nothing but gui issues (using a gtx 1660 ti), apps weren't working. So I went back to 24.04.

Anyways the problem(s) at hand.

The force reboot keeps happening. For no reason, I would be in the middle of a video, maybe I'm in the middle of writing code on visual studio code. Maybe I am doing my art design or whatever. Ubuntu will restart my computer for no reason. Doesn't ask, just does. This is a reoccurring problem I've been having with Ubuntu.

I have an xp pen artist 12 pro external drawing monitor. Sometimes when I am using it or it's connected, the display will stop working. Likewise it flickers on and off.

Apps flickers. Quite often actually. Between steam. Videos or websites on Firefox, they flicker at a constant rate. Probably happens about 10x a day in a 8 hour span of being on this computer.

The pointers and keyboards will randomly stop working. To the point that logging out does nothing. I have to force reboot. Wondering if this relates to being with a laptop and having hooked up devices. But shouldn't make a difference.

Now my question at hand is... How do I solve these issues? I have been trying different work around. Different drivers, upgrading Ubuntu. Downgrading. Changing settings. But nothing seems to work. I've only been using Ubuntu base for about 2 months now. Prior I've always used Budgie, Pop OS and even bazzite (also technically Ubuntu studio). But these problems seem to only occur on Ubuntu base.

To note, major reason I wanted to use Ubuntu base was for the sake of Visual studio code working somewhat flawlessly on here. Which it does.

Also I should note that I have run this specific laptop on Bazzite and PopOS. My other dual boot is bazzite.

I'm really new to command line, and I'm trying to move a folder full of FASTQ files into my directory. I haven't had any luck in the terminal, so I tried moving files using GUIs (nautilus and thunar). However, I can't move any files and I've been receiving these errors:

(thunar:865): GLib-GIO-CRITICAL **: 15:17:18.061: GFileInfo created without standard::size

(thunar:865): GLib-GIO-CRITICAL **: 15:17:18.061: file ../../../gio/gfileinfo.c: line 1845 (g_file_info_get_size): should not be reached

Any ideas on how to fix this or if I'm missing something?

I have a HP OfficeJet Pro 8500 that HP stopped supporting in Mac OS and Windows.

The printer works fabulously from Ubuntu with the HP supported driver.

I have been PDF'ing files and sharing to the Ubuntu device which has an automation to print any new files in a folder.

Can I do this better? I.e. have a driver that will print from latest Windows and MacOS rather than the faff of PDFing first?

I'd like my wife to just be able to hit file, print and be able to choose colour/bw and quality as with any other printer.

While trying to make a modification to a KDE4 subpackage for one of my retro-machines, I managed to break a good number of the other subpackages. My hunch would be that this has to do with using a newer compiler (gcc-9 from one of Ubuntu's own PPAs instead of gcc-5 that I used for the previous build from 10 years ago).

I'm now waiting for another build to finish that uses gcc-5 again, but it seems that this is a newer gcc5 than the one back then.

The old packages are still on the server, but are marked superseded. Fortunately I downloaded them because I feared I might have to roll back (as I can no longer properly do a local build).

Is there a way to bring those superseded packages back online? I had hoped that would happen automatically if I deleted the old version, but apparently not ... and I can't even fetch them with apt-get download foo=4:4.11<blabla>.

Thanks!

The last update of the Nvidia drivers failed and I had the message to send the failure report to Ubuntu 24.04. Since then, the display remains dark after the boot selection screen. I am unable to login.

I have two questions:

1. Is there a way to disable the GPU and use native graphics before the boot sequence?

2. What can be done to correct the driver issue?

I am developing a Qt app, and considering whether to use PySide6 and PyQt6.

Is there any difference between them in terms of:

• performance?

• resource consumption (RAM/internal storage)?

• compatibility with native look and feel in GNOME?

I installed Ubuntu 26.04 LTS Desktop on my Galaxy Book2 Pro 5G. It only has one SSD, and I created a shared partition named "shared" (D:). When using Strawberry Music Player, I always get an error message; I need to access the shared partition before I can play music files. So I was wondering if automatically mounting the shared partition would solve the problem. I occasionally mount it to /home/ku/shared, but Strawberry Music Player can't see the music files in the shared partition. I think I might be doing something wrong. I've attached some screenshots; I hope someone can help me. Thank you!

This seems wrong.

I have updated my Ubuntu from 25.10 version to 26.04, I received some error dusring the installation about the kernel.

At the first start I had a kernel panic error, I solved it starting my PC with the previous kernel version then I provided the following commands:

 sudo update-initramfs -u -k version

Now I can boot with any problem my PC with the latest kernel available 7.0.0-15.

But I think there is a problem, if I try to update my system via terminal this is what I have:

This is an extension of this question and of this answer. I asked some clarification there in the comments, but I received no answer.

I have a number of mp4 files, and their metadata title displays some undesirable text. I would be perfectly satisfied to replace that text with the file name, but without the file path and without the file extension.

If I use ... -metadata title="{}" ..., the title contains both the file path and the file extension.

If I use ... -metadata title="${basename}" ..., the title still contains the file extension.

So how should I modify the command to remove the file extension too?

As the link https://packages.ubuntu.com/search?keywords=boomaga&searchon=names&suite=all&section=all suggests, the Boomaga software is no longer available in Ubuntu 26.04.

I know that I can add the appropriate PPA and still use the old version (taking any risks).

However, my question is this:

What is the best way to easily preview printouts, rearrange pages, combine printouts, make booklets, or print multiple pages on a single sheet (all in one software) in Ubuntu 26.04?

I use fvwm, with sloppyfocus and autoraise (so that when a window receives focus, it automatically raises above overlapping windows). Since I upgraded to ubuntu 24.04.4, auto raise isn't functioning.

============================== Edited ===========================

Problem solved: I installed fvwm3 and used that instead of fvwm2, and all is now well. fvwm3 is working happily without my having to change my config file (which is in ~/.fvwm/fvwm2rc). I found the deb for fvwm3 at ubuntuupdates.org/pm/fvwm3 after I was unable to find it in the ubuntu repository (I've seen the claim that it exists in the universe repository, but apt said it wasn't available).

edit: my question is detailed enough to see it's not about how to install Firefox with the deb package, I've already edited it to follow someone's advice and have no idea what I should add.

Environment

• OS: Ubuntu 26.04 LTS (fresh install, last LTS)
• Hardware: AMD-powered laptop [Lenovo IdeaPad-Slim-5-15ARP1]
• Session: Wayland
• Firefox: installed from Mozilla APT repository (removed snap first)
• Thunderbird: installed from Mozilla APT repository (works, but shows warning)

What I did

1. Installed Ubuntu 26.04 LTS on a new laptop
2. Removed the preinstalled Firefox and Thunderbird snaps
3. Followed the official Mozilla instructions to add the Mozilla APT repository and install the .deb builds
4. Thunderbird launches normally
5. Firefox fails to start

Expected behavior

Both Firefox and Thunderbird should start normally from the APT packages, as on previous Ubuntu releases.

Actual behavior

• Firefox: crashes instantly and sometimes shows the Mozilla Crash Reporter instead of a browser window
• Thunderbird: starts, but prints a sandbox warning in terminal

Terminal output

Firefox:

Thunderbird:

Sandbox: CanCreateUserNamespace() unshare(CLONE_NEWPID): EPERM

What I've already checked

• Both applications were installed using the exact steps from the official Mozilla website for Ubuntu
• Thunderbird works despite the sandbox warning, Firefox does not
• Errors mention AppArmor (label="firefox (enforce)"), Wayland proxy bind permission, and unshare(CLONE_NEWPID): EPERM

Question

How do I fix the Firefox startup crash on Ubuntu 24.04 after replacing the snap with the Mozilla APT build? Is this caused by the new AppArmor user namespace restrictions, the Wayland sandbox, or a missing permission, and what is the correct way to allow Firefox to create its sandbox without reverting to the snap?

Attempt n°1: create an apparmor profile for the new Firefox installation.

I've looked for an example and copied a profile suggested on Reddit. It did not change the outcome:

sudo systemctl restart apparmor.service
[sudo: authenticate] Mot de passe :

My current system configuration is as follows:

• CPU: AMD Ryzen 9 9950X3D
• Motherboard: MSI MAG X870E
• RAM: DDR5-6000
• PSU: PX-2200

I am currently experiencing issues on Ubuntu 24.04 where installing the NVIDIA graphics driver leads to an infinite boot logo loop and a black screen.

While investigating the issue, I came across reports suggesting possible compatibility problems between the RTX PRO 6000 Blackwell and certain MSI motherboards.

I would appreciate it if anyone who is successfully using the RTX PRO 6000 in an Ubuntu development environment could share their motherboard model and a stable hardware configuration.

In particular, I would also like to know whether this GPU has known issues with specific chipsets (e.g., X870E), or whether the problem is more likely related to BIOS settings or driver configuration.

Starting an installation of Ubuntu 26.04 with full disk wipe using the graphical installer, I have an installation stuck at rsync command for 30+ minutes after an error.

rsync connection closed:

Please help me for installing libtinfo5 into 24.04.1 LTS.

I almost build a program for AWE in Ubuntu 22.04.2 LTS but a new version Ubuntu 24.04.1 LTS \n \l suddenly encountered (I installed with no doubt) without libtinfo5. Then my work stopped suddenly.

Your help would be much appreciated if you could please let me know any information on the installation of libtinfo5 into the new version Ubuntu 24.04.1 LTS.

I have the same error as described here... Couldn't Create Moklist: Volume Full - grub doesn't start at all

Disabling secure boot did not help.

I cannot boot into my OS and also with a liveUSB I cannot boot.

Laptop is an old ASUS. The OS on my HDD is Ubuntu and that is the only want I want.

I also read here... https://www.reddit.com/r/Fedora/comments/172azxc/live_usb_wont_boot_volume_full/ - that the only solution is to delete all the keys, reinstall them, save, and restart. I am just not sure how to do it. MY QUESTION: What I do first, second, third, etc.? It seems not recommended to do this (= risky), but I have no choice, so I want to do it right. Do I delete all keys at once and then what as to how to reinstall? Or do I just do the Platform Key (PK) and then either "set new key" or first "delete key" and then what? Or another or all listed secure boot variables?

Here some screenshots:

I noticed that my script is probably running in a wrong time (UTC maybe?). But I've added CRON_TZ into the crontab.

EDIT

It's Ubuntu 18.04, DigitalOcean.com droplet which was created from snapshot.

I've checked syntax and it is correct I think. Do you know where could be the problem?

CRON_TZ='Europe/Prague'
53 12 * * * touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

The script should be executed 12:53 Slovakia/Czech Republic time (in 24 hour format) but it wasn't - it haven't created a touch0.txt. If I execute it manually it works.

CONFIRMED

I tried to put there a command in UTC and it created a file (SK/CZ is 13:24 but UTC is 11:24 right now)

24 11 * * * touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

EDIT

It's 14:20 Prague time and I've set two jobs:

21 12 * * * TZ=Europe/Prague touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt
21 14 * * * TZ=Europe/Prague touch /home/futilestudio/feedproject/cronsupervisor/scripts/touch1.txt

and removed touch0.txt from the directory.

14:21 - created /home/futilestudio/feedproject/cronsupervisor/scripts/touch0.txt

When sshing into my machine, I see the following:

How to disable these advertisements, without disabling the update and login parts (the Want to make a highly secure kiosk, smart display or touchscreen? ... part)?

I have no idea how to set the display. I keep getting the following error error

xterm: xt error can't open display xterm display is not set

I have searched online but haven't found any solution. Please can anyone help me out ?

At first, I had this USB flash drive with a Ubuntu 14.04 LTS bootable in it. But now, I want to remove/wipe it and create a new bootable of another OS. First, I tried directly:

sudo cat file.iso > /dev/sdb; sync

As suggested in this thread. It didn't worked, returned

bash: /dev/sdb: Permission denied

So, I thought that this was happening because of it already containing a bootable and decide to wipe it. So I just shreded it

sudo shred -v /dev/sdb

After it, It wasn't appearing on the nautilus vertical nav as I sticked it into PC. So I made a file system for it sudo mkfs.ext3 /dev/sdb (I don't know if it's the right type of fs to make it but I was just testing anyway, if it isn't, please warn me about this)

Now, I access it through nautilus and I see that it is indeed empty. I'm trying to make that command I was doing in the beginning sudo cat file.iso > /dev/sdb; sync but still having the same "permission denied" again.

So, two questions on that, did this mkfs was applied correctly or I shouldn't do that? And, how do I solve my problem of making my bootable iso finally? (I don't want to use unetbootin, couldn't install it and I read that it could be done using cat/sync) Thanks in advance.

I follow this issue to configure PIdgin for MS Lync 2013 .

I get this message :

Web ticket request to https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc failed

Known that settings has been configured as following:

And No proxy:

i received this certificate from MS sysadmin .

And i don't know if it is useful in Ubuntu . If so , How can i import it?

And Why rproxy appeared in message error even there is no proxy in my settings .

I mean :

https://rproxy.mycompany.com:443/CertProv/CertProvisioningService.svc

UPDATE :

I found where can i import certificate :

However , i get new error message:

SSL Connection Failed
