I’m just not able to have this succeeds, whatever the mirror I use (mirror not shown in the command):

fakechroot fakeroot debootstrap noble root

It always ends with:

W: Failure while configuring required packages. W: See /…/root/debootstrap/debootstrap.log for details (possibly the package mawk is at fault)

And that file says:

Setting up base-files (13ubuntu10) ... Setting up bash (5.2.21-2ubuntu4) ... update-alternatives: using /usr/share/man/man7/bash-builtins.7.gz to provide /usr/share/man/man7/builtin> Processing triggers for libc-bin (2.39-0ubuntu8) ... Errors were encountered while processing: mawk

Is it an issue with the mirrors or with debootstrap? I tried multiple different mirrors, including the default one.

However, if I do the same for Debian Bookworm, on which I believe Ubuntu Noble is based, it can finish without any error:

fakechroot fakeroot debootstrap bookworm root http://ftp.fr.debian.org/debian/
…
I: Base system installed successfully.

Before each time I have a try, the root directory is emptied.

As a side note, I need it to try to compile an application which I am not able to compile on XUbuntu. I would like a fakechroot environment to try some things without polluting or breaking the system in use. May be I can use the Debian Bookworm minimal system for that, but I’m not sure, and anyway, it would be cleaner with the Ubuntu Noble minimal system.

I'm using new Ubuntu (26.04) but there it writes something like this: No KScreen module found. Please check your KScreen installation.

How can I fix it? I tried install it but KScreen doesn't exist.

I want to set up a MongoDB architecture using only two physical Ubuntu servers, without the possibility of adding a third server or an external arbitrator.

My system:

Server 1 will be my primary server, and everything will be written to it.

Server 2 will be my backup server, copying data from Server 1.

I want Server 2 to automatically become "writable" when Server 1 completely shuts down or crashes.

My questions:

I only have two servers. Is it possible for MongoDB's own system to automatically make the second server "writable" when the first server completely shuts down or crashes? In other words, can Server 2 automatically write when Server 1 shuts down?

If MongoDB cannot do this automatically, what is the most accurate and common way to solve this problem with only two servers?

Thank you in advance for your answers.

I switched from Windows to Ubuntu. I downloaded Google Chrome. When I opened it, it is stuck. I couldn't able to write a URL. I could just close it. I also download Brave browser and Microsoft Edge. The same thing is happening with them too.

I have tried to reinstall, but nothing changed.

(Gnome 50/Resolute)

I am aware that I can change the search provider ordering. What I am asking about are the results e.g. pictured below ("LibreOffice", "Power", and "Suspend"), which I am calling the "main" results, for lack of a proper term:

This screenshot also depicts the use case: In past versions, "Suspend" was the first result for "sus", meaning five keystokes (super-s-u-s-enter) to suspend. However, I am now seeing two extra results ahead of "Suspend" (no idea what in "LibreOffice" is matching, by the way), so now I have to take my fingers off the home row and press ➡️➡️ before enter. Champagne problems, I know, but I'd still like to know if there's a way to change the ordering or maybe blacklist certain applications for certain search terms. Is there?

Relatedly, I've read but not confirmed that gnome tracks selection frequency (or more likely frecency, not sure) and reorders results, so I should expect to see "Suspend" bubble up to the top after a few uses, but that hasn't yet happened.

I'm new to Ubuntu GNOME 24.04, but screen sharing isn't working. I tried switching to X11 (like uncommenting #WaylandEnable=false in /etc/gdm3/custom.conf and verifying echo $XDG_SESSION_TYPE), configuring the NVIDIA drivers, toggling hardware acceleration, and rebooting, but nothing worked. The issue persisted even when using Vesktop, however recording via OBS works perfectly fine.

systemctl --user status pipewire
systemctl --user status wireplumber

Both are enabled, but I received this.

It still doesn't work even with acceleration disabled via discord --disable-gpu --disable-features=VaapiVideoDecoder,VaapiVideoEncoder,VaapiIgnoreDriverChecks,UseChromeOSDirectVideoDecoder,UseMultiPlaneFormatForHardwareVideo.

What could be the problem?

Using the Raspberry Imager I am burning Ubuntu Core on to a CM5.

Strange issues.

First, using this link to download images https://cdimages.ubuntu.com/ubuntu-core/24/stable/ these are my results:

After burn and on first boot,

current build --> does not boot (sticks and loops around ubuntu flash screen not ubuntu core splash screen)

05-01 build --> works fine.

05-15 build --> works fine.

06-01 build --> same failure current build has (see above)

06-03 build --> same failure current build has (see above).

The CM5's I am purchasing are from PiShop. I have only had this issue with PiShop CM5's that I purchase. They do some sort of testing process that I believe may mess up partitions.

Any idea what is going on here?

Thanks, Will

I'm trying to update my Ubuntu computer from 24.04.4 LTS to the latest LTS version (26.04), and along the way in that process I'm getting this error:

Could not calculate the upgrade 

An unresolvable problem occurred while calculating the upgrade. 

This may be caused by unofficial packages installed on the system. 
Please try replacing the following packages with official versions 
from the Ubuntu archive, and then try the upgrade again.

How would I go about removing libcamera so that I can update?

As requested this is the output of apt policy gstreamer1.0-libcamera:

I had an issue I used AI to solve and thought I would pass it along. I followed all the advice but couldn't get my controller to work wireless. I will add the summary of diagnostic steps and solution below. I hope this helps someone. :

PS3 DualShock 3 Bluetooth on Ubuntu 24.04.4 LTS (Kernel 6.17)

Problem
-------
- Controller worked perfectly over USB.
- Bluetooth paired and connected but Steam never detected it.
- No /dev/input/js0 was created.
- bluetoothctl showed Connected: yes but Paired: no/Bonded: no.
- sixpair successfully programmed the controller with the PC's Bluetooth MAC.

Diagnostics
-----------
1. Verified hardware
   - USB controller detected.
   - hid_sony kernel module loaded.
   - Wired controller worked in Steam.

2. Verified Bluetooth transport
   - btmon showed:
     * ACL connection established.
     * HID Control (PSM 0x11) connected.
     * HID Interrupt (PSM 0x13) connected.
     * Controller transmitted HID reports (A1 01 ...).
   - Therefore Bluetooth and pairing were NOT the problem.

3. Verified device creation
   - udevadm monitor showed:
       add uhid
       add hidraw6
       remove hidraw6
   - HID device was created then immediately destroyed.

4. Found kernel errors
   journalctl reported:
       sony ... unknown main item tag 0x0
       sony ... Failed to set controller into operational mode
       sony ... failed to claim input

Root Cause
----------
BlueZ was using the UserspaceHID (UHID) backend, which failed to initialize
the DualShock 3 correctly on this system.

Fix
---
Edit:

    sudo nano /etc/bluetooth/input.conf

Set:

    UserspaceHID=false
    ClassicBondedOnly=false

Restart Bluetooth:

    sudo systemctl restart bluetooth

Ensure HIDP is loaded:

    sudo modprobe hidp

Reconnect controller:
    1. Plug USB in briefly.
    2. Unplug.
    3. Press PS.

Verification
------------
Successful fix produced:

    /dev/input/event27  PLAYSTATION(R)3 Controller Motion Sensors
    /dev/input/event28  PLAYSTATION(R)3 Controller

Controller became visible to evtest and Steam.

Useful diagnostic commands
--------------------------
btmon
bluetoothctl
sudo udevadm monitor --kernel --property
sudo journalctl -k -n 100 --no-pager
ls /dev/input/event*
ls /dev/input/js*
sudo evtest

Notes
-----
- sixpair is still required once to program the controller with the PC's
  Bluetooth MAC address.
- This controller is a genuine Sony CECHZC2U A2. ;

The Editing of the /etc/bluetooth/input.conf file as above was the solution. 

It simply freezes during installation and does not progress forward. I've tried different USB sticks, disabling Secure Boot, and nomodeset.

I have had many GPU problems in my current install of Kubuntu (I keep things as updated as possible). The previous GPU, an RX 580 8gb, had overheating issues (now found to be a hardware problem) and a system crashing issue, and now my RX 5500 xt 8gb also has a problem of randomly crashing in the game Cyberpunk 2077, and so far nowhere else. The game seems to be unstable on its own, as it can crash and glitch outside of graphics crashes. I am running it in medium graphics in windowed mode, on proton hotfix.

I have followed the guide "Dummy's guide to AMD GPU Issues", and besides enabling "amdgpu.gpu_recovery=1" in grub (which hasn't stopped crashing), this is the output I have been able to gather of all the goings-on in my system:

https://pastebin.com/knywXCRc

If needed, the crash that happens is that the game will freeze, the GPU won't send signal anymore and when it gives any signal it's all artifacts, the system being unresponsive.

I'm trying to figure out a concept on how to create a system that is installed on a RAID and has both encryption and self-healing (checksumming) capabilities, however, so far, I have failed to come up with a solution that has no issues.

Please consider the following as guidelines:

• A laptop (or other machine) that has two separate drives installed (SSD)

• Drives should be configured as RAID 1 against single drive failure, because unique data is saved onto them on the go (photos, videos, client's notes, passwords, etc.)

• RAID array should be able to boot in a degraded state, if absolutely necessary

• RAID array should be transferable, in case of laptop hardware failure (no hardware RAID)

• Data should be encrypted, because laptop is susceptible to theft and sensitive data should not be accessible by foreign parties

• (Strictly optional, but highly desired): Data should be safe against any form of corruption in the long term

I've read into a couple of different technologies that accomplish some of these criteria, but I can't make them work together to create a system that fulfills all of them. So far, I've considered:

md-raid: Does not know about data corruption, will brainlessly write any data to all active devices, whichever gets read first, gets loaded. RAID on top of encrypted block devices may fail to boot on single drive failure (?).

btrfs: Does not know about encryption. If btrfs is located on an encrypted md-raid device, it does not see individual underlying drives = no self-healing and no use for btrfs in the first place (in this specific scenario).

dm-crypt+dm-intergrity: No easy way of opening block devices (integritysetup) to boot the system, initramfs must be manually modified = no update-stability. RAID on top of encryption issue again.

ZFS: No native kernel support. Too... problematic to do.

Is there any other way to accomplish this that I have missed or anything that I got wrong? If somebody has done this before or knows of a configuration that would solve all these points, I would be glad to find a solution.

I'm trying to upgrade my Ubuntu Server to the latest LTS (26.04) from 24.04, but do-release-upgrade fails:

root@aragorn:~# lsb_release -a

To upgrade to the latest non-LTS development release

I do not want a development release, so I left the prompt to lts in /etc/update-manager/release-upgrades

How can I do it?

I tried to remove Ubuntu from Windows so that I could install a new Linux distribution. However, the garb always pops out. I think my Windows 10 files are still safe.

Was looking up how to share my files between my two Ubuntu computers.

Found this question: How do I set up file sharing between two Ubuntu laptops on my wireless network?

But that's for 12.04. Very old. I have 24.04 and 26.04 LTS straight from the Ubuntu Desktop website.

Presuming the 12.04 was the most direct one as well, most minimal install the iso allows etc, do I still need to install openssh-server or anything, to move files over the network?

I'm currently using Ubuntu 26.04 LTS. When I first installed it, everything worked perfectly. I'm also quite new to Linux, so I've relied on ChatGPT a lot for help.

While using Ubuntu, I occasionally removed applications that I didn't need. Following ChatGPT's advice, I usually removed applications with:

sudo apt purge <app>

and then ran:

sudo apt autoremove

I was told that sudo apt autoremove only removes unused libraries and that if other applications still needed those libraries, they would either not be removed or could be reinstalled automatically, so it shouldn't affect the system. I trusted that advice.

After some time, I installed and removed many applications while trying to find software that suited my needs, and I'm sure that after uninstalling applications, I often ran sudo apt autoremove.

At some point, I started noticing that some system applications became slow or partially broken. For example, when I click a file upload button in a web browser and the file picker dialog opens, the file picker becomes very laggy and slow, although it doesn't completely freeze.

In addition, my default App Center now crashes and shows the following message:

"Is Not Responding. You may choose to wait a short while for it to continue or force the app to quit entirely."

I also experience the same issue with the RustDesk remote desktop application.

This makes me suspect that I may have accidentally removed some library that these applications depend on. I've also noticed that this problem seems to affect mainly applications built with Flutter, while most other applications work normally, except that a few of them become laggy during certain operations, like the file picker example I mentioned.

Is there any way to diagnose and fix this problem without reinstalling Ubuntu? I have a lot of important data and would really prefer not to reinstall the operating system.

I have already tried uninstalling and reinstalling the affected applications, but the problem still persists.

Have searched and found conflicting info..

Can Gnome on 26.04 run as an X11 session?

Or do I have to install/run XFCE or similar?

Mainly need this to run NoMachine on a headless server.

Thanks.

My Ubuntu 24.04.4 LTS is installed on a dual-boot Dell Inc. Precision 5490 machine.

Every time I close my laptop's lid and the machine goes in suspension mode, when I get the lid up again the machine shows the screen with date and time but does not awake when I press enter or any other keys. The only thing I have been able to do at that point is to brute force power down by holding the power button pressed. This happens randomly, not all the times. I would prefer not doing this as forcing the machine to turn off this way might compromise the disk. What can I do?

I have a message that I can update my Logitech Universal Receiver firmware.

Looked up instructions, which use fwupd. Was told to use snap for Ubuntu version 22

sudo snap install fwupd --classic 

But then I remembered it said to uninstall the "apt version", so I did:

sudo apt remove fwupd

But now when I enter fwupd, it says 'command not found'. I tried the snap install command again, it says fwupd is already installed.

I'm tolerably familiar with command lines, system paths, etc., but don't really understand apt, snap, or fwupd. Can someone please help me get the fwupd back, then I can start trying to update the Logitech Universal Receiver software.

Intel I219-LM on Lenovo M90n-1 IoT detected in PCI but e1000e probe fails on Ubuntu 24.04.3 LTS Server

I’m trying to use the second Ethernet port (Intel I219-LM) on a Lenovo ThinkCentre M90n-1 IoT running Ubuntu 24.04.3 LTS Server, but the NIC never initializes. The Realtek NIC works normally.

Ubuntu does detect the I219-LM in lspci, and the correct Intel driver (e1000e) loads, but the driver probe fails with error -2, and the interface never appears in ip a.

System

Output shows:

• lo
• enp2s0 (Realtek RTL8111/8168 with a valid IPv4 address)

The Intel NIC never appears as an interface (normally it would be something like enp0s...).

What I have tried

• Fresh reinstall of Ubuntu 24.04.3 LTS Server
• Updated to latest Lenovo BIOS
• Verified both NICs are enabled in BIOS
• Swapped cables, ports, and switches
• Booted with the Intel port connected and disconnected
• Confirmed the e1000e kernel module is loaded

Behavior is always the same:

• The Realtek NIC works perfectly.
• The Intel I219-LM is visible in PCI, but e1000e fails to probe it and no network interface is created.

Additional test: Windows 10 works on the same hardware

To rule out hardware failure, I booted the exact same ThinkCentre M90n-1 IoT from a Windows 10 Pro portable USB with the Ethernet cable plugged only into the Intel I219-LM port (Realtek port unused):

• Windows detected the Intel NIC.
• It obtained an IP address via DHCP.
• The machine was reachable on the LAN and had working network connectivity.

So:

• The Intel I219-LM hardware and port are known-good.
• BIOS configuration appears sufficient for the NIC to operate.
• The failure seems specific to the Ubuntu 24.04.3 + in-kernel e1000e + Lenovo OEM NVM/firmware combination, not a physical or cabling issue.

Intel documentation

Intel’s official driver README for this NIC says:

• I219-LM is supported
• Ubuntu 24.04 LTS is supported

Intel also states:

“If you purchased an OEM-branded system, contact your OEM for an SW/FW version compatible with your exact NVM. Using mismatched SW/FW versions may affect performance or stability.”

This suggests Lenovo may use a Lenovo-specific NVM/firmware for the I219-LM on this model.

Question for AskUbuntu

• Is this a known issue with the I219-LM on Ubuntu 24.04.3 LTS Server (kernel 6.8) on the ThinkCentre M90n-1 IoT?
• Does the in-kernel e1000e driver need a different version or special module options for this OEM firmware/NVM?
• Could this be caused by an Intel NVM or ME/UEFI firmware mismatch on this Lenovo platform?
• How can I further debug what probe of 0000:00:1f.6 failed with error -2 actually means here?

Any help or pointers on getting the Intel I219-LM to initialize properly on this system would be greatly appreciated.

I want to install Ubuntu 22.04 LTS with a custom partitioning setup, including an encrypted root partition and a swap partition of 8 GiB. The default Ubuntu installer doesn't allow me to set a custom swap size. What can I do to achieve this?

After upgrading to Ubuntu 24.04, my external monitor stopped working. I have an NVIDIA graphics card, the NVIDIA GeForce RTX 3060, and I installed NVIDIA driver version 560.35.03. My output from the nvidia-smi command is shown.

I have tried multiple versions of drivers (535, 550, 555, and 470), but nothing works.

I tried completely removing the NVIDIA driver multiple times with sudo apt-get remove --purge *nvidia* and reinstalling it with a clean installation.

My kernel version is updated to 6.8.0-44-generic.

Secure boot is DISABLED too.

prime-select is set to the nvidia option.

When I run the command for Ubuntu drivers, I get the output: udevadm hwdb is deprecated. Use systemd-hwdb instead., however all drivers show up afterwards. This message appears x times, where x equals the number of available NVIDIA drivers.

output for xrand --listproviders is below

$ xrandr --listproviders

Providers: number : 1

Provider 0: id: 0x45 cap: 0x9, Source Output, Sink Offload crtcs: 4 outputs: 3 associated providers: 0 name:modesetting

I have found a guide for that but doesn't sure if it will work or it is safe to use. The guide: http://www.linuxandubuntu.com/home/how-to-automatically-change-gnome-background-in-intervals-using-bash

I am asking if is these introductions safe and will work? If not, is there any other solutions for that?

I am using Ubuntu 20.04 LTS

Thank you.

I would like to reinstall a snap package due to a missing library file (removing and installing the snap again fixed this problem on another system).

How can I avoid the uninstall step (thus preserving my settings) and install again?

I have installed the certificate but when I try to access the url with https it gives me 403 forbidden error, but when I try to use it with http it is working fine.

I have installed the certificate in /etc/ssl/certs/ and I have following files:

1. test.key
2. test.ca-bundle
3. test.crt

In apache I have placed .conf file in

I don't know what wrong I am doing here.

OS = Ubuntu 18.04 LTS PC = Lenovo Ideapad Y500 (released 2012) Wireless card = Intel Centrino Wireless N2230

I just installed Ubuntu 18.04 LTS on an old Lenovo Ideapad (notebook) model Y500. It works OK, but for WiFi to work, I have to provide these commands in a Terminal:

sudo modprobe -r iwlwifi
sudo modprobe iwlwifi 11n_disable=1

This works, but only for a little while. If the computer goes to sleep (or is rebooted), I have to give these commands again.

1. I have no clue what these commands do.

2. Whatever these fixes, I would like to make permanent.

3. When this works, WiFi speed is horrible (about 20 Mbps), but wired ethernet speed is wonderful (about 930 Mbps - I have fiber internet).

I have no clue what Ubuntu sees as my WiFi card. If this were Windows, I could look at the Device Manager and see what Windows thought it is (which can be wrong). With Linux, I'm too stupid to figure out what the OS thinks the card is.

Is it possible that Ubuntu is misidentifying my wireless card? If yes, can I fix this (and improve speed) by using a different driver?

This is somehow a follow up of this question:

How can I detect the BPM (beats per minute) of a song?

But now instead of detecting them in songs, I want to generate them.

I am looking for an application that will output a sound (something short like a beep) a configurable number of times per minute.

If I say 20bpm, it will output that sound every 3 seconds. (60/20)
If 60bpm, every sec.
If 120bpm every half a sec.

The reason for this is that I am learning how to play drum sets and the bpm looks really important. I am following this video on youtube.

update

Seems they are called metronomes and even Google got one. Cool Stuff.

Thanks Nick.

While it is installing (any version of Ubuntu) it pops up with a message saying:

grub-install dummy failed. This is a fatal error.

I have Windows 8 already installed on my computer which is a HP Envy dv7. I have not installed Ubuntu yet, because I can't. Any idea on what to do?
