Radicale does not work after restore from backup

[kopfkind]

@Avron I had a similar issue recently and was able to make it work as described here:

Radicale is inactive

I’ve not found the root cause, yet. But I’ve managed to get my radicale installation back into working state by doing the following: Make a backup copy of all data from /var/lib/private/radicale Uninstall radicale via plinth web UI Verify that data folders have been purged, nothing remains Reinstall radicale via plinth Check the data folders, they were still missing This is not surprising, since radicale is activated by socket, so without a connecting client, the service will stay disabled. …

Tl;dr: Purge, reinstall and manual restore of the data files incl. chowning them properly.

Hope this helps!
