OpenLP crashing on startup (Ubuntu 20.10)

gellert

Sorry, I need help again. I'm now on Ubuntu 20.10 and I can't start OpenLP, it crashes. I cleaned up OpenLP with

$ apt-get purge openlp

and removed

.config/OpenLP
.local/share/openlp

reinstalled to start with a clean installation but it does not solve the issue.

$ apt show openlp

Description: Church lyrics projection application
 OpenLP is free church presentation software, or lyrics projection software,
 used to display slides of songs, Bible verses, videos, images, and even
 presentations for church worship using a computer and a data projector.

I get this on startup:

I experience the exact same behaviour on my ubuntu 20.10. I also attempted to disable all plugins (status=0 in OpenLP.conf) and initialised OpenLP anew for another user - all resulting in segmentation fault.

Just to mention: OpenLP trunk runs without any problem.

Similar issue on Linux Mint 20, fresh install of the OS and OpenLP, but it won't start.

After creating/chmoding /var/crash (which didn't exist), the first error went away, leaving only the "cannot import name 'dir_util'..." error.

@jlg89tx, thank you for your suggestion. Unfortunately it doesn't help me: python3-distutils and vlc is already installed.

@gellert I don't see an error in your log file, can you tell me what happens when OpenLP crashes?

gellert

Hi @raoul, thanks for the replay. I do not see anything useful, except segmentation fault. I hope this screencast tells you something: https://youtu.be/Yfumd-tGLoU
