Overview

This utility is a fancy wrapper around syncevolution and cron and it creates or removes connections to remote carddav/caldav servers. This utility was created specifically to work on Ubuntu Touch but it may work in different environments.

Get the Code.

git clone https://github.com/UT-ilities/UTouch_CalDAV_and_CardDAV_synchronization.git
cd UTouch_CalDAV_and_CardDAV_synchronization

How To Use

Configure server URLs, credentials, and naming preferences.

cp config-nextcloud-template.txt config-personal.txt
vim config-personal.txt

Executing setup-dav-sync.sh --contacts config-personal.txt or setup-dav-sync.sh --calendar config-personal.txt will read your configurations, connect to the specified carddav/caldav server, synchronize data and setup a cron job to keep this device in sync with the server.

Executing setup-dav-sync.sh --delete-contacts config-personal.txt or setup-dav-sync.sh --delete-calendar config-personal.txt will read your configurations, remove them from syncevolution configurations and remove all data from this device only (the data on the server will not be affected).

Using Multiple Carddav/Caldav Servers.

Simple specify multiple configurations files and a single command will process them all.

setup-dav-sync.sh --contacts --calendar config-personal.txt holidays.txt team-awesome-schedule.txt

Known Bugs

1. When a contact is delete from Ubuntu Touch using the native Contacts app syncevolution will relay this change to the carddav server as a 'modification' of the contact and it will not be deleted from the server and other clients synchronized with the server will still have this old contact.
2. Even after a calendar has been removed it will still show up as an available calendar in the Ubuntu Touch native calendar app.

Recommendations for Nextcloud Users.

I do NOT recommend using this utility to synchronize calendars hosted in Nextcloud. The online accounts feature of Ubuntu Touch does a better job. I do recommend using this to synchronize contacts.

Pull Requests Are Welcomed

I am only able to test configurations and servers I use, which currently is Nextcloud. I will be happy to incorporate changes which allow a larger audience to benefit from this project.
