Anki does not work on Ubuntu 24.04.2

[ankylosaurus]

Hi! I am trying to install anki 25.09 on ubuntu 24.04.2 and encountering some problems. I will describe what I have tried. Please let me know if anyone has suggestions about how to fix anki on my machine.

• I downloaded anki 25.09 and followed the installation guide
• When I tried to run anki, I saw an error screen that said “Anki encountered a problem. Please follow the troubleshooting steps.” I copied the debugging info, some of which I included below.

Anki 25.09.2 (3890e12c)
Python 3.13.5 Qt 6.9.1 PyQt 6.9.1
Platform: Linux-6.8.0-87-generic-x86_64-with-glibc2.39

Traceback (most recent call last):
File “/home/username/.local/share/AnkiProgramFiles/.venv/lib/python3.13/site-packages/aqt/progress.py”, line 121, in handler

• I then uninstalled anki, deleted all associated files, and restarted my computer.
• Next, I downloaded anki 25.09 and again followed the installation guide. I still received the same error message when attempting to run anki.
• I followed a post (that I can’t link) and ran sudo sysctl -w kernel.apparmor_restrict_unprivileged_userns=0, but still can’t run anki.
• I also followed the System Qt versions instructions at the install and upgrade manual, but remain unable to use anki.
• Now when I run anki, I see

• I also receive the above error message when I run anki --no-sandbox in my terminal.
• Now if I search for anki and try to open it on my computer via the GUI, nothing opens.

I’d appreciate any guidance. Thank you!

I assume you followed Install & Upgrade - Anki Manual and the forum entry you couldn’t link to was Issues running on Ubuntu 24.04?

On my debian I have a lot of other python3 files that seem relevant, maybe try installing them on ubuntu:

python3-pyqt6
python3-pyqt6.qtmultimedia
python3-pyqt6.qtqml
python3-pyqt6.qtquick
python3-pyqt6.qtsvg
python3-pyqt6.qttexttospeech
python3-pyqt6.qtwebchannel
python3-pyqt6.qtwebengine
python3-pyqt6.sip

Could you provide the full error message (after redacting usernames etc.)?

[ankylosaurus]

@Anon_0000 Yes, you are correct, I did follow the Install & Upgrade - Anki Manual instruction. You are also correct that I couldn’t link to “Issues running on Ubuntu 24.04.”

I tried installing the files you listed, then ran anki again in my terminal. Here is the resulting error message that I see in terminal. Hope this is helpful, @llama.

Thank you both for your responses.

[llama]

Do you have mpv installed and present in PATH?

[ankylosaurus]

@llama I ran sudo apt install mpv and now when I run anki in my terminal, the program opens. Thank you!
