Looking for a simple card/cal/WebDAV server that runs in docker.
Have tried Davis, Radicale and Baikal but have either struggled to get them working or found them a bitch to maintain.
Doesn’t have to be a DAV type solution. Syncing/backing up contacts and calendars from an android phone is essential.
it kinda sounds like you failed to back them up and are attempting to restore them from a non-backup.
and yeah, pulling an integral, configured component and expecting it to just run fine seems kinda… psychotic.
