I was recently planning to install macos on my ThinkPad, but I accidentally formatted my SSD into GPT. For a while, everything was ok. I restarted to boot into macos, but i forgot a kext. So I tried booting back into ubuntu but the error mentioned above came. Any fixes?

How do I get the Ubuntu set up screen from an iso image on usb? https://askubuntu.com/questions/1563028/how-do-i-get-the-ubuntu-set-up-screen-from-an-iso-image-on-usb

My windows pc crashed & I can’t get back into windows. Get asked for account login, but my company account no longer exists. I’m trying to install Ubuntu 24.04 from an iso image created on a usb using rufus to see if I can access my documents that are on my laptop, but when I load from usb I just get the grub command screen rather than the Linux setup screen. Any help welcome

Bluetooth earbuds connect but do not expose A2DP sink on Ubuntu 20.04, while other earbuds work on the same system https://askubuntu.com/questions/1563025/bluetooth-earbuds-connect-but-do-not-expose-a2dp-sink-on-ubuntu-20-04-while-oth

Bluetooth A2DP sink not appearing on Ubuntu 20.04 (device-specific issue) that I've narrowed down to device-specific behavior.

System

  • Ubuntu 20.04 (PulseAudio, X11)

  • BlueZ default from focal

  • PulseAudio running as user (not root)

  • No PipeWire (tested, reverted)

  • Desktop: GNOME on Xorg

  • Audio output via HDMI normally works

Devices tested

  • EarFun Air Pro 4 (problematic)

  • boAt earbuds (~₹400) (works perfectly)

Expected Behavior

When opening the earbuds case:

  1. Bluetooth connects
  2. An A2DP sink appears immediately
  3. Audio output switches automatically or is selectable

Actual Behavior (EarFun Air Pro 4)

  • Bluetooth connects successfully (shows in GNOME Settings)
  • Often no bluez_sink.*.a2dp_sink appears
  • pactl list short sinks sometimes shows only HDMI
  • Audio output does not switch
  • Manually reconnecting Bluetooth or starting playback sometimes forces A2DP to appear

This occurs even when:

  • Multipoint is disabled
  • Earbuds are paired only to the PC (no phone)
  • Across reboots

Relevant Command Output (When Broken)

$ pactl list short sinks
0 alsa_output.pci-0000_00_03.0.hdmi-stereo-extra1 SUSPENDED

Bluetooth logs repeatedly show:

bluetoothd: a2dp-sink profile connect failed

PulseAudio Bluetooth modules are loaded:

$ pactl list short modules | grep bluetooth
module-bluetooth-policy
module-bluetooth-discover
module-bluez5-device

Attempting to load them again fails (as expected):

$ pactl load-module module-bluetooth-discover
Failure: Module initialization failed

Control Experiment

On the same laptop, same OS, same user session:

boAt earbuds:

  • Connect
  • Immediately expose A2DP
  • Appear in Sound Settings
  • Work reliably every time

This strongly suggests the OS audio and Bluetooth stack is functioning correctly.

Things Already Tried

  • Reset PulseAudio user state
  • Restarted Bluetooth and PulseAudio
  • Forced card profiles and sinks via pactl
  • module-switch-on-connect
  • module-device-manager
  • Delayed Bluetooth module loading after X11 startup
  • PipeWire migration (A2DP negotiation failed on 20.04; reverted)
  • Cleared /var/lib/bluetooth

Hypothesis

The EarFun firmware appears to delay or withhold A2DP profile commitment, possibly prioritizing call or multipoint behavior. Android handles this by aggressively forcing A2DP, whereas Linux (PulseAudio with BlueZ) does not, resulting in a connected-but-no-sink state.

Question

Is there a Linux-side way (PulseAudio or BlueZ) to:

  • Force A2DP profile commitment for such devices, or
  • Prevent connected-without-sink states for earbuds that delay A2DP exposure?

Or is this effectively a firmware compatibility issue with certain modern TWS earbuds on Linux?

Clarification

I am not looking for generic advice such as switching to PipeWire or upgrading the OS. I want to understand whether this behavior is fixable on the Linux side or fundamentally device-dependent.

Windows enters recovery mode when booted via GRUB https://askubuntu.com/questions/1562994/windows-enters-recovery-mode-when-booted-via-grub

I'm trying to get my pc dual booted with Windows and Ubuntu. I have both operating systems installed. However, I'm running into the issue that when I boot Windows from GRUB, it automatically goes into recovery mode (Ubuntu boots fine from GRUB). When I select to boot Windows in the BIOS, Windows boots normally without any issue.

I have tried adding custom entries to GRUB (including the one from the accepted answer in this post), but it still enters recovery mode. How do I solve this problem?

Stuck at initial welcome screen of the Ubuntu 25.10 installer https://askubuntu.com/questions/1562985/stuck-at-initial-welcome-screen-of-the-ubuntu-25-10-installer

I have an old 3rd gen Asus k55vj laptop with Core i5 3rd gen, Intel 4000 S graphics with 8 GB RAM and a GeForce GT 635M dedicated GPU. I want to install Ubuntu 25.10 as Windows is unable to detect my dGPU and the laptop fans are spinning at maximum speed even though there are no processes or CPU stress. During the installation of Ubuntu I got stuck at the welcome screen, not even getting the option of choosing the language.

I again restarted in safe mode and successfully installed Ubuntu in safe mode, but after the installation it asked me to remove the drive and press Enter, but failed to start the newly installed Ubuntu 25.10. How to resolve this? I know the dGPU of mine is a failed card because it is old. Please help me to get rid of the fan noise and save my laptop.

What's happening on Ubuntu kernel? [closed] https://askubuntu.com/questions/1562852/whats-happening-on-ubuntu-kernel

I really don't understand what's wrong with Ubuntu. NVIDIA proprietary drivers (the most recent 590.48.1 and 580.129.06) can be compiled successfully in other distributions' kernel-6.19 kernels, but they just can't be compiled successfully in its own kernel no matter which Release Candidate.

5.1 audio channels getting randomly mixed up https://askubuntu.com/questions/1553642/5-1-audio-channels-getting-randomly-mixed-up

I am a new Linux user, freshly migrated from Windows and I'm having a technical problem with 5.1 audio. In short, the output randomly switches audio channels. The problem is, it is random. Sometimes is plays correctly, sometimes not.

I have spent the last few days searching the internet for an answer, but couldn't find anything. Re-mapping the channels permanently doesn't apply, since on paper everything looks ok and half the time it works ok.

Now, in more detail: when playing a video (both online - youtube, and offline - VLC), the sound channels get randomly mixed up. Front-left is coming from rear-left, front centre from rear right, etc. When I pause the video, go into system settings / audio and switch between playback devices, the channels usually get corrected (it often takes quite a few tries though). And then it randomly reappears again. Usually after I pause / unpause or rewind a video. It also happens in games.

I am on Kubuntu 24.04, plasma version 5.27.12, kernel 6.14.0-24-generic. My speakers are SteelSeries Arena 9, connected to the motherboard via USB. MB is MSI X870E Carbon wifi, BIOS 1.A52 (14 July 2025).

I have checked the PulseAudio output devices and configuration, I tried Pipewire volume control, qpwgraph - nothing helps. Neither do I see anything strange in aplay -L, all looks in order.

If it was a case of permanently mixed up audio channels, I guess it would have been easier to figure out and re-map them, but since it is random, I have no idea what the issue is.

Anyone has any advice what this could be and how it can be fixed?

Update 29 July: as I was getting a bit irritating behaviour in Kubuntu with some activities, I switched to Pop! OS and then to Cachy OS (I will probably stick to this one).

This audio issue is present in both of them. So Ubuntu and Arch based distros. Which leads me to think this could be linked either to PulseAudio or the way 5.1 sound is managed in Linux in general. I'm really puzzled by this. Anyone else ran into a similar issue?

Is there an ARM version of Ubuntu Desktop (latest version)? https://askubuntu.com/questions/1538084/is-there-an-arm-version-of-ubuntu-desktop-latest-version

Is there an ARM64 version of Ubuntu Desktop (latest version)?
I would like to know the iso link.

Failed to mount "917 MB Volume" https://askubuntu.com/questions/1529980/failed-to-mount-917-mb-volume

I'm a new user, following the official guide to install Ubuntu 24.04.1 LTS, and whenever I try to actually install it on my new PC, it keeps giving me an error message saying:

Error mounting /dev/loop2 at /media/ubuntu/disk: /dev/loop2 already mounted or mount point busy

Does anyone know how to fix this?

If it helps, I'll note that I built my PC (for the first time)

EDIT 1: For those asking:

  • I downloaded the Ubuntu 24.04.1 LTS image
  • Flashed it onto a USB drive using balenaEtcher
  • Plugged it into my new PC before booting it
  • Followed the instructions of the installation wizard exactly
  • Chose interactive installation, extended selection, both recommended software options
  • Finally chose to erase the disk and install.

Additionally, the PC I built was only connected to the internet via ethernet cable

EDIT 2: My PC boots in UEFI mode, has 64 GB RAM, and a 2TB SSD

Also, I'm so new to Linux that I don't know how to run something like:

sudo fdisk -l (ele)

EDIT 3:

I forgot to mention this in my original question because of everything else going on, but sometime when I get to the disk setup stage, it only gives me the option of manual installation, and when I attempt to follow a tutorial to do so, it crashes, and only then gives me more options

EDIT 4: Result of sudo fdisk -l

Audio not working. Ubuntu 24.04 https://askubuntu.com/questions/1511648/audio-not-working-ubuntu-24-04

I am new to linux. I don't know any file structures or any tools. I checked some threads and tried but its not working for me. I have included SS. Only dummy test is shown in sound box.

transfer files from icloud and one drive to desktop running ubuntu https://askubuntu.com/questions/1451981/transfer-files-from-icloud-and-one-drive-to-desktop-running-ubuntu

I cannot download file folders from iCloud drive and OneDrive to my computer. I can on Google Drive. Photos are fine and individual files but not file folders.

Is there a way without individually downloading each and every file?

How do I use the softdog module? https://askubuntu.com/questions/1246187/how-do-i-use-the-softdog-module

I am trying to use the software watchdog kernel module called softdog. I am not sure how to use it properly.

I have removed the module from ...

/etc/modprobe.d/blacklist-watchdog.conf

Then I have run...

modprobe softdog

This resulted in the following line in dmesg...

│[60656.721980] softdog: initialized. soft_noboot=0 soft_margin=60 sec soft_panic=0 (nowayout=0)

So it seems like softdog was initialized correctly.

Once softdog initializes the files /dev/watchdog and /dev/watchdog0 are created.

But I have not started a watchdog daemon, so I assume no one is feeding these files (no clue why there is two).

I am expecting that because I do not have a watchdog daemon installed, that softdog will reboot the system....but this is not what I am seeing. (fyi I plan on installing a watchdog daemon once I can confirm that softdog module is capable of restarting the system).

Has anyone ever successfully configured the softdog module to work as a software watchdog?

pdsh: how to run a commands that require root/sudo privileges https://askubuntu.com/questions/1223777/pdsh-how-to-run-a-commands-that-require-root-sudo-privileges

I have implemented a small beowulf cluster for testing purpose, all nodes with Ubuntu server 18.04.

I have installed pdsh for running the same command on ssh at the same time on multiple node. ssh login is granted passwordless with public/private key distribution over the nodes (example: https://www.rittmanmead.com/blog/2014/12/linux-cluster-sysadmin-ssh-keys/) .

If I try a simple command like "date" , all is fine:

me@master:~$ pdsh -w me@node[0-3] date
node0: Mon Mar 9 18:56:04 UTC 2020
node2: Mon Mar 9 17:26:15 UTC 2020
node3: Mon Mar 9 16:42:37 UTC 2020
node1: Mon Mar 9 17:42:52 UTC 2020
me@master:~$

But if I try a command that require a sudoer privileges like this:

me@master:~$ pdsh -w me@node[0-3] apt update

then it returns these errors:

node0: WARNING: apt does not have a stable CLI interface. Use with caution in scripts.
node0:
node0: Reading package lists...
node0: E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
node0: E: Unable to lock directory /var/lib/apt/lists/
node0: W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied)
node0: W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)
pdsh@node00: node0: ssh exited with exit code 100

and so on for all other nodes.

The problem is the "apt update" command that require a sudo execution but I have not found a way to pass it with pdsh

The same kind of commands launched with "real" root user runs fine:

root@master:~$ pdsh -w root@node[0-3] apt update

But in this case this means actually enabling the "real" root user on all nodes, which I would like to avoid.

Is it posssible? Is there a way for running elevated privileges commands with pdsh without enabling the root user? Or are there alternative tools that can do this?

Using GParted how do I move the unallocated to the right side of my main Ubuntu partition so I can extend it? https://askubuntu.com/questions/1217462/using-gparted-how-do-i-move-the-unallocated-to-the-right-side-of-my-main-ubuntu

I wanted to shrink more my Windows partition into at least 100 GB more and add that to the current 107.42 GB unallocated space. My main goal is to extend /dev/sda8 (main Ubuntu partition) to use the unallocated space. I watched this video Extend Ubuntu Disk Volume with GParted after Resizing Hard Drive, but I can't move/resize /dev/sda8 to the left side of unalloc or move unalloc to the right side of /dev/sda8. How can I get pass through the left of ext4, grub2core, and linux-swap?

Info and questions from my screenshot:

  1. /dev/sda4 is my Windows partition.

  2. /dev/sda8 is my main Ubuntu partition.

  3. Where is my extended here?

“No suitable Destination Host found by cups-browsed” https://askubuntu.com/questions/1128164/no-suitable-destination-host-found-by-cups-browsed

I am running Ubuntu 18.04.2 Desktop on my laptop.

I have installed CUPS to a Raspberry Pi running Raspbian. My Mac will consistently print to this printer without any problems.

From Ubuntu Desktop I am only able to print to the printer ~1 minute after a reboot of Ubuntu Desktop. After that time documents will not print.

When I visit ‘localhost:631’ from Ubuntu Desktop the status is listed as ‘Idle - “No suitable Destination Host found by cups-browsed”’ (see attached).

How to install libqt5 https://askubuntu.com/questions/999520/how-to-install-libqt5

Trying to run rtklib on ubuntu 16.04.2 and getting this

I'm guessing I need to install libqt5? If so how to install it can someone give me some instruction?

Resume from suspend close all programs https://askubuntu.com/questions/853042/resume-from-suspend-close-all-programs

I have an Asus K550J. Whenever you suspend either via command line (pm-suspend) even through lid, apparently okay because of blinking LEDs, but when I restart the PC all programs were open are closed as if it had just been started and has not recovered!

I'm on Ubuntu Gnome 16.10 in dual boot with Windows 10.

Photo & video viewer similar to Android's Gallery app https://askubuntu.com/questions/849128/photo-video-viewer-similar-to-androids-gallery-app

Are there any Ubuntu programs that allow us to view a folder's videos and photos in one integrated viewer in the same way that Android's Gallery app functions?

With Nautilus I have to browse the photos separately, and then browse the videos in a separate video application. However, since videos are often taken at the same time as the photos, I would like to be able to view them all in sequence.

Is this a gnuplot 5 problem or an ubuntu package problem? I have installed gnuplot5-qt and gnuplot5-X11 just to cover my bases. Are there any other packages or the like that may be missing? Thanks in advance for any help!

Ubuntu 15.10 randomly crashing back to login screen https://askubuntu.com/questions/691070/ubuntu-15-10-randomly-crashing-back-to-login-screen

fresh install of Ubuntu 15.10 here. Everything works fine, but I'm getting random crashes back to the login screen.

I pasted my syslog here: http://paste.ubuntu.com/12989589/

Edit: Confirmed bug on intel video driver + compiz with windows animations enabled. Workaround:

  • Edit or create: /etc/X11/xorg.conf.d/20-intel.conf
  • Add the following:

    Section "Device"
     Identifier "Card0"
     Driver "Intel"
     Option "AccelMethod" "uxa"
    EndSection
    

This disables "sna" acceleration, and uses "uxa" instead (the old one)

Unable to do remote desktop using xrdp https://askubuntu.com/questions/234856/unable-to-do-remote-desktop-using-xrdp

I have an Ubuntu virtual machine to which I need to do remote desktop. I do not have physical access to that machine and I can do only ssh to the machine. I wanted to do remote desktop and came up with lot of options (vnc, xrdp, opennx). I used xrdp and I installed the necessary packages in the ubuntu machine (xrdp and dependent). Then I enabled the remote access in the ubuntu using the following command line option.

gconftool-2 -s -t bool /desktop/gnome/remote_access/enabled true

gconftool-2 -s -t bool /desktop/gnome/remote_access/prompt_enabled false

Then I restarted the xrdp (/etc/init.d/xrdp start). But when I try to do rdp using the windows client (mstsc), I get the following error. Remote access to the server is not enabled.

How do I solve this? Kindly help.

Easiest way to setup a SMTP server to receive mail? https://askubuntu.com/questions/157371/easiest-way-to-setup-a-smtp-server-to-receive-mail

I want to setup a SMTP server to receive all mails.
I have only found mail sending software so far (like postfix).
But I want to have software to make the server being able to receive mails.

Bonus points if it could work like temporary mailsites, like mailinator.com (I know, but no DNS MX forwarding advice please) and fakemailgenerator.com.
