Server auth requiring double login

[ljfriese]

Hey,

First off, awesome software.

I'm encountering two odd behaviours with my calibre server, wondering if there is a fix or if it's just a side effect of my potentially odd set-up.

Behaviour 1: I have to log in twice when accessing the server. That is, I enter the username/password, submit, the login modal returns, I re-enter, submit, and I'm in.

Behaviour 2: On boot up my server logs some warnings:

Anything to be concerned about there?

My potentially-odd build that I mentioned is:

I'm running calibre 5.12 (aware it's not fully up to date) on a headless debian server hosted on a raspberry Pi 4b. The calibre library is being synced onto the pi via rsync from Dropbox.

1 is probably because of 2. 2 is complaining about a read only database, so check the permission on the users database (--userdb)

[ljfriese]

Thanks - That led me to the solution.

I created the userdb as a root user and then was running the server non-root. Non-root didn't have write permissions to the db.

Fix: sudo chmod 777 /srv/calibre

Both issues are resolved.
