What is the problem?
Octoprint doesn't start.
What did you already try to solve it?
First try wiht Helper script via:
Then tried to reinstall in Debian 12 / Ubuntu 22.04 / 24.04 VM (whith octoprint_deploy script).
Since the error occurs in all tested Linux versions – which I find strange – I will continue to analyze the error in Ubuntu 24.04 LTS with all current updates.
Have you tried running in safe mode?
Yes. Result:
