telnet connection refused on xubuntu 26.04 https://askubuntu.com/questions/1566974/telnet-connection-refused-on-xubuntu-26-04

I've install several packages trying to get telnet working on Xubuntu 26.04. I'm getting the error

I've also installed openbsd-inetd and inetutils-inetd.

How do I get telnet working on 26.04

Ubuntu machine cannot boot after replacing libgfortran library https://askubuntu.com/questions/1566973/ubuntu-machine-cannot-boot-after-replacing-libgfortran-library

I am on an Dell machine with Ubuntu 24.04

To try fixing an error on a software I mistakenly changed a /lib/x86_64-linux-gnu/libgfortran.so.3 with a version that was probably incompatible with the system. The machine immediately froze and cannot reboot. I tried rebooting with a USB live (hitting Fn+F12 at the Dell logo) but I get a bunch of errors like those in the attached screenshot. I am unsure how I should proceed?

Is there an Ubuntu patch for ssh-keysign-pwn yet? [duplicate] https://askubuntu.com/questions/1566963/is-there-an-ubuntu-patch-for-ssh-keysign-pwn-yet

I'm just wondering if there is a patch for CVE-2026-46333 (aka ssh-keysign-pwn) yet?

I assume not, but wanted to double check to see if anyone knows anything,

So far I've gathered that we are to use this mitigation:

sudo sysctl -w kernel.yama.ptrace_scope=3 echo 'kernel.yama.ptrace_scope = 3' | sudo tee /etc/sysctl.d/99-ssh-keysign-pwn.conf

sudo sysctl -w kernel.yama.ptrace_scope=3

echo "kernel.yama.ptrace_scope = 3" | sudo tee /etc/sysctl.d/99-ptrace-hardening.conf

sudo sysctl --system

If there is any news, let me know, however I don't think there has even been a security patch for dirtyfrag yet lol

Boomaga is not available in 26.04. What now? https://askubuntu.com/questions/1566961/boomaga-is-not-available-in-26-04-what-now

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 have tried many of the options as available from the community but none seems to work (at least for my simple installation of Ubuntu 22.04).

Many thanks.

Sound card randomly disappearing/disconnecting in Ubuntu 26.04 https://askubuntu.com/questions/1566957/sound-card-randomly-disappearing-disconnecting-in-ubuntu-26-04

I own a Digidesign Mbox 2 sound card, and have been using it with Ubuntu with no problems. Since I upgraded to 26.04, the sound card disappears randomly with the audio output cutting out and the device disappearing from the output menu.

If I enter alsa force-reload into the terminal, the sound card will come back and continue to work. Is there anything I can do to prevent the sound card from disconnecting randomly?

How to adapt apt_repository in ansible in Ubuntu 26.04 https://askubuntu.com/questions/1566955/how-to-adapt-apt-repository-in-ansible-in-ubuntu-26-04

I have used ansible to install firefox with the following block:

- name: Add Firefox repository
  apt_repository:
    repo: 'ppa:mozillateam/ppa'
    state: present
    update_cache: no
  become: yes

This has always worked but stopped working after switching to Ubuntu 26.04, giving the following error:

TASK [Add Firefox repository] **************************************************

I read that apt_repository is being deprecated in Ubuntu 26.04. But I am not sure whether it is the cause here.

Can someone help explain how I can fix the ansible block to install from the PPA?

This is with:

I have a 2014 MacBook Air 6,2. My wifi and camera don't work and will have to be worked out. These items should just work out of the box with no messing about! I'm sure I am not the first nor the last to have these issues. I should think that these sort of issues could be worked out during installation. Why not?

I have this keyboard layout on a HP laptop. As you can see, I have the keys [ and ] around the space bar, & to the right of the space bar, _ near backspace, - near the right shift key.

Sadly all these extra keys, including the backspace key, do not work. Anyone with a solution?

How do I fix my computer's black screen after boot? https://askubuntu.com/questions/1566944/how-do-i-fix-my-computers-black-screen-after-boot

My computer is:

Host: Blade 14 - RZ09-053  
OS: Ubuntu 24.04.4 LTS x86_64  
CPU: AMD Ryzen AI 9 365 w/ Radeon 88  
GPU: NVIDIA c4:00.0 NVIDIA Corporation

neofetch in terminal

When I try to boot into it from power off, I unlock the disk with the disk password, the Ubuntu logo shows for a bit, flickers off, on, and then off... and then the screen goes and stays black.

I am able to boot into recovery mode from Grub, and then I can log into my user and use the OS normally.

The NVIDIA driver I use, found in Software & Updates, is nvidia-driver-595-open.

I also often get an error after booting into the OS and using it for a few minutes with the Title:

Xorg assert failure: Xorg: ../../../../dix/privates.c:382:dixRegisterPrivateKey:Assertion '!global_kays[type].created' failed

a screenshot of the beginning of the error

I believe they may be connected because I assume the screen going black is a driver issue, but I don't know.

Another thing to note is that sometimes my computer just randomly freezes, with no input available, and I have to power it off, which also sucks and might be related.

I have already done sudo apt update and sudo apt upgrade, I've done a lot of searching.

Thank you!

Bad sound in Ubuntu 26.04 https://askubuntu.com/questions/1566941/bad-sound-in-ubuntu-26-04

I am using a Lenovo Legion R9000P ADR10 laptop. The internal speakers produce a very flat, quiet, and tinny sound with absolutely no bass. It feels like the subwoofers/woofers are completely disabled, and only the tweeters are functioning. Audio works perfectly fine under Windows, confirming it is a Linux driver/kernel configuration issue (missing pin quirk for this specific model).

  • Audio Codec: Realtek ALC287

  • OS: Ubuntu 26.04 LTS (Resolute)

Removing blue tones in Linux https://askubuntu.com/questions/1566937/removing-blue-tones-in-linux

I have been trying to find a PDF viewer on Linux where I can remove blue tones. I am a beginner with this operating system and I still do not know it very well. I have gone into system settings and I have seen that it is possible to remove blues there, but it only affects the desktop; when I open the PDF viewer, the blues are not removed (nor in the browser). I would like to know if there is any program that can do this or if it is possible in some way to have a PDF viewer where blue filtering can be applied.

Duplicate cursors are appearing when taking screenshots or attaching a second monitor https://askubuntu.com/questions/1566663/duplicate-cursors-are-appearing-when-taking-screenshots-or-attaching-a-second-mo

I have a Gigabyte g5 kc laptop with an Intel Core i5 10500H and a laptop Nividia RTX3060 running Ubuntu 24.04.4.

When I take a screenshot there is a high chance that my cursor gets deposited on the screen where it was at the time of taking the screenshot and sometimes when attaching a second monitor. These cursors persist above everything until I restart sometimes they are displayed over the shutdown screen. They are also not just static images as they can react to what the current mouse is doing changing to click sprite or typing sprite. I say chance because it doesn't happen every time with screenshots. It's consistently around 50%. As for connecting a second monitor I only just noticed that happening today, so I do not know the percentage of that.

Cursor Gif

I don't think it is the graphics driver, as I changed it and the issue persisted. It also persisted whether I was on Wayland or Xorg. I also tried a bunch of screenshot tools the standard Ubuntu screenshot, GNOME Screenshot and Flameshot to name a few and they all do it.

Speaker-related issues https://askubuntu.com/questions/1566416/speaker-related-issues

My Galaxy Book2 Pro 5G's speakers were working, but after restarting the computer, the sound disappeared again. So I tried running some code, and the sound came back.

I executed the following commands:

wget https://github.com/joshuagrisham/galaxy-book2-pro-linux/raw/main/sound/necessary-verbs.sh
chmod +x necessary-verbs.sh
sudo ./necessary-verbs.sh

Is there a way to automatically execute some code with this effect at boot?

How to robustly connect to Android phone with KDEConnect/GSConnect when travelling between different networks, just like Apple ecosystem? https://askubuntu.com/questions/1565782/how-to-robustly-connect-to-android-phone-with-kdeconnect-gsconnect-when-travelli

I use KDE Connect between my phone and laptop on my University WiFi. Very often, the IP address changes and the connection stops working. I have to manually find the IP of the computer with the command ip address and put it in my phone and connect manually. The same thing happens when I connect to a different network.

Is there any way to automate the connection process? AFAIK know Apple's computers have some robust connection procedure with iOS devices.

I want to be able to do this for multiple computers with the same phone.

No sound from snap Thunderbird on new Ubuntu installation https://askubuntu.com/questions/1565628/no-sound-from-snap-thunderbird-on-new-ubuntu-installation

I had to reinstall Ubuntu 24.04 LTS on my Dell Latitude 5510, and all is well except that Thunderbird does not play any sound. Prior to reinstall it worked well, and I was notified when a new mail arrived.

ALSA works well (verified by using aplay to play sound files), and all other GUI apps with sound are working.

I have tried to connect the Thunderbird snap to ALSA:

sudo snap connect thunderbird:alsa
[sudo] password for bernt:
error: snap "thunderbird" has no plug named "alsa"

So that was not the thing to do.

Run sigrok without root https://askubuntu.com/questions/1132246/run-sigrok-without-root

I am trying to run sigrok with real HW. However, running pulseview, there is no real HW possible. I suspected that this was due to sigrok not having the privilege to access the HW, and so I ran it as root, and I was able to access the HW.

My question is: How do I run this without root? I assume I need to change the gid or uid of the device file to be able to access it. If so:

  • How do I find out the device file for the HW?
  • How to do this cleanly? .i.e. automate this when the HW is disconnected and reconnected.
  • Which gid? is there a convention?

In case it is relevant
