Hi, if you check the requirements it says Python 3.10 or above, maybe that is the reason? The error states that it could not commit to the sqlite DB, maybe due to permissions on the filesystem, but as you would git cloned the setup, it does not seem likely, do check with the below command, ouput from my setup.

ls -l WGDashboard/src/db/ total 596 -rw-r--r-- 1 root root 49152 Aug 28 10:31 wgdashboard.db -rw-r--r-- 1 root root 12288 Aug 27 09:32 wgdashboard_job.db -rw-r--r-- 1 root root 544768 Sep 4 11:32 wgdashboard_log.db

This is due to the nature of async access of SQLite.. I'm trying to fix this issue

[donaldzou]

Refer to #354

Thank you, but for the time being is there a workaround for the users?

I would not as many peers are connected and I have no backup of the panel, any problem on the way makes trouble.
