How do I clear local calendar events cache and re-sync?

  • 772

I recently started using a Nextcloud instance for my calendar events. I am able to sync events so they show up in the GNOME Calendar app, but there are many duplicates. Is there some place where events are cached locally where I can examine them or clean them up?

The events display properly in the Nextcloud Calendar app -- I don't see any duplicates. I only see the duplicates in GNOME Calendar.

I looked in locations mentioned in In what file does gnome-calendar store calendar events? but I didn't see any actual calendar event data, just references to the calendar webdav URIs.

I tried deleting and re-adding my Nextcloud account in the "Online Accounts" settings dialog. I tried disabling and re-enabling Calendar synchronization for my Nextcloud account.

I'm using:

  • Ubuntu 20.04 LTS
  • Nextcloud 19.0.3 (latest stable)
  • GNOME Calendar 3.36.2
calendar nextcloud 20.04 gnome-calendar

    Looks like they are in SQLite3 databases under ~/.cache/evolution/calendar/. I was able to trash that directory and it automatically re-sync'd. Yay!

    The duplicates still exist; this separate issue might be with the Nextcloud database. I downloaded the ics file for the calendar from Nextcloud and I do see what appear to be duplicates in there.

  2. Quit all evolution items (see ps ax | grep evolution):

    evolution --force-shutdown

    and clear cache:

    evolution --force-shutdown

    Restarting evolution will show how the appointments are loaded back into the calendar.
