Can't launch Anki Ubuntu 24.04

Anki Help
1

I tried to start Anki today on Ubuntu 24.04, after having not used Anki for at least five months. I believe the last time I successfully launched it was on Ubuntu 23.10.

It would not launch from the app icon, or from the terminal.

I tried uninstalling and reinstalling at the command line, then I tried installing the latest Beta version, all to no avail.

Here are some of the launch commands I tried.

I moved this to the appropriate category. Since you first found this issue with 24.04 – this isn’t a beta-testing issue related to 24.10.

I won’t be the one who can help you troubleshoot something on Linux, but some basics to get you started –

  • Have you worked your way through the Linux platform notes? Linux - Anki Manual

  • Since unexplained crashes after upgrading are often add-on related – have you tried restarting in safe mode? Troubleshooting Checklist #2

  • Have you tried the rest of the things on the Troubleshooting Checklist?

That helped. I followed the instructions to change the settings and reboot.

sudo nano /etc/default/grub

Change the following:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=0"

Then update Grub.

sudo update-grub

Reboot.

sudo reboot

Problem solved.
