I frequently run backportpackage to upload .deb source packages to a PPA to have them build on Launchpad and get published there. In recent days this has been (permanently?) failing:

$ backportpackage ...
...
Uploading to ppa (via ftp to ppa.launchpad.net):

Uploading screen_5.0.1-2~bpo26.04.1~1778812240.930c295+master.dsc: [Errno 104] Connection reset by peer

Any suggestions what might be going on? Is this related the recent issues that has taked down all of Launchpad recently in April/May 2026?

I'm stuck at "Booting a Command List" trying to boot a 26.06 USB on a Lenovo Thinkstation P710 B30 - dual XEON, 16GB ram. From 2016/2017.

I've tried: nomodeset, acpi=off, removing quiet splash (and combinations of those). Never get anything.

Any other suggestions? The machine has a working Fedora 24(?) system on it (and a windows partition)

I have a laptop with an onboard Radeon 680M and a RTX 4050; checking nvidia-settings, it does not show the option to switch between the gcards, while calling prime-select query the following options are shown: nvidia|intel|on-demand|query (I don't have a intel)

Is the Radeon not supported or I should try a different approach?

I'm using Kubuntu 26.04 with kernel 7.0.0-15-generic. After suspending the system with Meta+L and leaving the computer for a while, I encounter this screen.

I'm forced to perform a hard reboot via the power button or use the REISUB to restart. Has anyone experienced this, or knows a solution?

I am planning to migrate my main Workstation from Windows to Ubuntu 24.04 LTS (GNOME 46). Since i want to stay on Wayland for my daily driver. I want to ensure a 1:1 input feel for a mix of competitive games without having to switch back to X11.

Hardware:

• NVIDIA RTX 5060.
• Intel Core i5-13400F.
• Wayland (GNOME 46) with 125% Fractional Scaling.

Upgrading from 25 to 26.04, upgrade hangs on "setting up wvdial". Now i can't boot into my previous install, the startup process results in a kernel panic. I can restart the update process from recovery mode, but it still hangs in the same place. How do i get either my old setup back or the upgrade completed without wvdial?

Edit: rebooted into linux 6 recovery mode, dropped down to root shell and did

sudo apt remove wvdial

Which removed it, and then apt just automagically went on to finishing the upgrade

My system wont upgrade because it says I have a unofficial version of libopenexr 3 1 30. How can I reinstall the official version? I have not tried anything at point because i don't know where to start.

I have a number of hosts running Ubuntu in a lab managed by ansible. Ansible is used to upgrade and install specific deb and apt packages.

I've just upgraded one to 26.04 LTS. The upgrade caused a problem with ansible, triggered by the transition to sudo-rs.

How can I specify for a specific machine a different sudo executable; in this case, /usr/bin/sudo.ws?

I am using Ubuntu 24.04 LTS on a ThinkPad E15 Gen 5 with an Intel i3 13th Gen processor.

I always keep the system in “Power Saver” mode. However, sometimes after booting the laptop, I notice that the power profile has automatically changed to “Balanced” mode without me changing anything manually.

Is this expected behavior in Ubuntu 24.04, or could this be a bug?

Has anyone else experienced this issue, and is there a way to force the system to always stay in Power Saver mode across reboots?

I was trying to use these commands to install Firebird on Windows Subsystem for Linux (I'm new to this).

wget -O firebird.tar.gz https://github.com/FirebirdSQL/firebird/releases/download/R2_5_9/FirebirdSS-2.5.9.27139-0.amd64.tar.gz

then:

tar -zxvf firebird.tar.gz

then:

sudo ./install.sh

And I typed my password. All I got was: sudo: './install.sh': command not found

What am I doing wrong? I used this instruction (It's a Polish website, but you can translate it.): https://dgcs.pl/firebird3-0-linux/

I have installed Ubuntu for the first time, and the fans are not working at all, regardless of the load.

Laptop Model: OMEN by HP Gaming Laptop 16-xd0xxx

Base Board: 8BCD

CPU: AMD Ryzen 7 7840HS
GPU: NVIDIA GeForce RTX 4050 GPU in a laptop

What I have tried:
I tried going into /sys/class/hwmon/ and there in hwmon6, whose name is hp, both fan speeds are 0 and not updating, and pwm1_enable is set to 2

I ran this command also: ls /sys/kernel/debug/ec/ec0/io 2\>/dev/null || echo "EC not accessible" and it outputs EC not accessible

How do I make the fans work?

Does anyone know what the problem is?

I am using Ubuntu 25.10 and I think my PC may have been compromised by malware or a trojan.

The reason I suspect this is because:

• My ad blocker suddenly stopped working.

• Some messages were deleted from my email account and Instagram account without my permission.

• I am worried someone may have gained access to my accounts or system.

I do not have much experience with Ubuntu or Linux security, so I am not sure how to properly check my system.

So far I have tried:

• Running ss -tulnp to check open ports.

• Checking running processes manually.

• Trying to use debsums, but it was not installed.

I would like to know:

1. How can I verify if my Ubuntu system is infected or compromised?

2. What logs or commands should I check?

3. How can I determine whether the problem is in my PC or only in my online accounts?

4. What immediate security steps should I take?

Hey guys I've been encountering plenty of problems in Kubuntu 26.04 that wont let me use my pc normally:

1. Translucently and wobble window effects get reapplied after each reboot without my consent

2. Chrome on xorg with using the built in classic option from appearance aka colors, the title bar buttons disappear when I try to type on the address bar.

3. Plymouth animation appears during transition from sddm to desktop (I have selected None as a transition)

4. The locale on the time widget in taskbar rejects any effort to be changed and still uses the Greek time format ΠΜ, ΜΜ, When I clearly set it to American am pm. I use Greek only for the keyboard

I have to note that I also use klassy I seriously need to find a solution because the name implies LTS and I am disappointed.

Can anyone help me? Plasma 6.6.4 Just upgraded

How to fix them?

I have bought a printer, an HP Envy 6500e. Although the driver is available, my notebook with Ubuntu 24.04 installed is not able to install it. It shows the printer as available, but it fails to install.
I tried with the standard Ubuntu installation procedure and using the hp-setup command.
I have also updated hp-plugin and I tried to connect the notebook to the printer through the USB cable or by Wi-Fi indicating the IP address manually.

I tried the printer using a Windows PC and Android smartphone and it works.

In all cases the printer installation failed. Any ideas?

I recently installed Ubuntu 26.04 and I noticed that the thumbnails for my comics aren't showing in the Files file manager. I tried installing different thumbnailers, but nothing seems to work. Instead it just shows the default Ubuntu document icons.

I do not have Evince or mcomix installed. I'm using the default document reader that comes with Ubuntu 26.04.

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!

I have an ASUS Vivobook 18 M1807HA with an AMD Radeon 780M integrated GPU running Ubuntu 24.04 (kernel 6.17.0-20-generic).

Problem

When running on battery power only, my laptop generates constant USB device connection/disconnection sounds (the "ding-dong" notification) every 60-90 seconds. The desktop icons sometimes refresh/update when this happens.

This does NOT happen when the AC adapter is plugged in.

What I've tried

I've investigated extensively and found that:

1. Running sudo udevadm monitor shows constant drm/card1 change events:

KERNEL [1192.228486] change   /devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm)
UDEV  [1192.261376] change/devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm)
KERNEL [1231.346665] change/devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm)
UDEV  [1231.370399] change/devices/pci0000:00/0000:00:08.1/0000:03:00.0/drm/card1 (drm)

2. Setting amdgpu.runpm=0 in GRUB does not resolve the issue
3. Disabling WiFi does not resolve the issue
4. power_dpm_force_performance_level remains unchanged during events
5. No error messages appear in dmesg

Workaround

Disabling system event sounds stops the audible notification:

gsettings set org.gnome.desktop.sound event-sounds false

However, the underlying issue (constant drm change events) persists.

Questions

1. Is this a known bug with the AMD Radeon 780M on battery power?
2. Has anyone else with recent AMD Ryzen AI laptops experienced this?
3. Is there a proper fix beyond disabling notification sounds?

I've already reported this as a bug to the AMD DRM developers, but I'm curious if others in the Ubuntu community have encountered this issue.

System info:

• Laptop: ASUS Vivobook 18 M1807HA
• GPU: AMD Radeon 780M (integrated)
• CPU: AMD Ryzen 7 260
• Kernel: 6.17.0-20-generic

This is the error shown after I shutdown:

I am new at using linux, and I am currently using Ubuntu 20.04. I use Ubuntu via a external HDD(WD 1TB). The HDD is two years old.

Recently this error has been popping whenever I shutdown and the OS too is lagging.

Any help will be greatly appreciated.

I cannot see where to disable alert sounds on Ubuntu 20.04. I believe it was available under Sound Settings in older versions of Ubuntu. "Alert sound" is there but not a corresponding volume.

1. Is there an alternative way to do this?
2. If this is not possible from Settings, who on earth decided that was a good idea? Thanks!

I am trying to install conjure-up to install the kubernetes on my ubuntu (16.04.1) with the command:

sudo snap install conjure-up --classic

After a few seconds, the below error is shown:

error: unable to contact snap store

I have both http_proxy and https_proxy already setup

Below is the output from snap version

snap    2.34.2
snapd   2.34.2

kernel  4.15.0-42-generic

I came across the similar question, Problem with snap store but the answer provided (issue with snap store try after some time) did not solve my issue.

Summary: how to configure the netplan on a host machine to create a bridge (with a static IP address) that would be used on guest virtual machine (shall be accessible from a local lan).

I am using Ubuntu 17.10, 32 bit. nplan 0.32~17.10.1.

I am trying to configure a linux virtual container that should be accessible from the local network. But I am failing to configure a bridge on host machine with the nplan.
I have tried to follow the following guide with no luck:
https://discuss.linuxcontainers.org/t/static-ip-for-containers-with-local-lan-access/817
The guide configures a host system with two NICs. My host machine has a single interface.

I am still dealing with the nplan configuration on my host machine. My nplan config on host machine is the following:

network:  
  version: 2  
  renderer: networkd  
  ethernets:  
    ens32:  
      dhcp4: no  
      dhcp6: no  
      addresses: [10.0.0.247/24]  
      gateway4: 10.0.0.138  
      nameservers:  
        addresses: [10.0.0.138,8.8.8.8,8.8.4.4]  
  bridges:  
    br0:  
      interfaces: [ens32]  
      dhcp4: no  
      dhcp6: no  
      addresses: [10.0.0.248/24]  
      parameters:  
        stp: false  
        forward-delay: 0  

after 'netplan apply' on host machine I can resolve google.com, but I can not ping:

ping google.com  
PING google.com (172.217.22.174) 56(84) bytes of data.

       valid_lft forever preferred_lft forever  

When I remove the complete section 'bridges:' from the nplan config I have to reboot the computer to get rid of the bridge (netplan apply is not enough - why?).

After the reboot, I can ping google.com.

Any help with the nplan configuration (on host and also on virtual guest) would be very welcome.

Thank you.

This happens to me all the time. What I actually want to do is "Ctrl+A, Shift+|". But instead, I accidently hit "Ctrl+A, Shift+C". And it brings me to a new instance of screen.

But there are some output on my last screen which I would like to reference later. Wonder how to get back to it?

I'm trying to migrate to my new NVMe Samsung 950 pro.

chroot /mnt/boot-sav/nvme0n1p3 update-grub
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.

Process:

• Copied/pasted via Gparted (lastest gparted live-cd)
• Ran boot-repair (with 15.10 ubuntu desktop)
• failed on update-grub

http://paste.ubuntu.com/13244403/

Old drive had:

• sda1 fat32 EFI
• sda2 ntfs
• unallocated (had to shrink a small amount for new drive)
• sda3 ext4
• sda4 linux-swap

My first guess is that I'm no longer using an sd, but an nvm prefixed device.

Any thoughts/help is appreciated.

$ update-grub
grub-probe: error: cannot find a GRUB drive for /dev/sda1.  Check your device.map.

When I look in /boot/grub I do NOT have a device.map. I read that I don't need one for grub2, but I generated one, ran update-grub and ran into the same message as above.

I attempt to reboot anyway, and my EFI only shows a Windows Boot Manager as a bootable item, for which it lands on a windows recovery screen. The Ubuntu partition isn't listed as a bootable drive in EFI.

Is there a list of Ubuntu versions with default corresponding Linux kernel versions somewhere?

I would specifically like to know the most recent version of Ubuntu that still used Linux Kernel 2.x.

I have a RAID-5. I'm trying to replace a failing drive in Disk Utility GUI. I added a new drive as a spare, then did "Remove Component" for the failing drive. How do I tell it to actually use the spare (write all the parity data, etc)?

I tried re-adding, because I got nervous...

$ sudo mdadm /dev/md127 --re-add /dev/sdd

mdadm: --re-add for /dev/sdd to /dev/md127 is not possible

In a terminal window, I can use File > Open Tab to get two tabs in the same window.
Then, if I move the terminal up to the top of the OS, those two tabs become two separated windows.

How can I merge those two windows back to one (like I had before)?

Does anyone have any good ideas as to native MySQL GUI clients for Ubuntu?

So far I've tried MySQL Workbench, which never seemed to work properly, phpMyAdmin which I found a bit slow, and Navicat which is a windows port and runs under wine, but none of these is perfect. In an ideal world, I'm looking for something like a native version of navicat.
