Calendar and contact sync with Nextcloud #

In the settings dialog under Online Accounts, add a Nextcloud account. If 2FA is enabled for Nextcloud, create a new app password before.

Legacy #

Note: These instructions are not necessary anymore. Instead, follow the steps above.

Gnome Calendar and Contacts can sync with CalDAV and CardDAV servers, they just don’t expose that functionality through their UI. Instead, the servers need to be added to Evolution. (1)

To add the CalDAV server (for use in Gnome Calendar), open Evolution and in the File menu under New, click Calendar. Select the type CalDAV. Enter the calendar’s Name and select a Color. Then enter the calendar’s link for the URL and specify the User. Click Apply. (2)
If 2FA is enabled for Nextcloud, create a new app password to use.

To add the CardDAV server (for use in Gnome Contacts), open Evolution and in the File menu under new, click Address Book. Select the type CardDAV. Specify a Name and the URL.

TODO: Backup to backup1 using Vorta.

TODO: Syncthing is currently not in use.

Set Syncthing to start automatically:

systemctl --user enable syncthing.service
systemctl --user start syncthing.service

Increase the inotify limit: echo "fs.inotify.max_user_watches=204800" | tee -a /etc/sysctl.conf

The web UI is then available at
