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.
git clone https://github.com/UT-ilities/UTouch_CalDAV_and_CardDAV_synchronization.git
cd UTouch_CalDAV_and_CardDAV_synchronization
Configure server URLs, credentials, and naming preferences. We assume that you can use non-sytandard NextCloud setup (different network port and 2FA enabled) so you need to provide:
- a real NC user (
USERNAME) - a Device credentials (
NCLOGIN) (see https://docs.nextcloud.com/server/latest/user_manual/id/session_management.html) - a network port that NC is accepting connections on (
NCPORT) that defaults to 443
In case of a standard setup (default port and no 2FA enabled) USERNAME and NCLOGIN should be the same and PASSWORD is your NC user pass.
cp config-nextcloud-template.txt config-personal.txt
vim config-personal.txt
In order to login using your Device(App) password (thus not exposing your real NC user and pass and bypass oAuth) in current NC version (starting from NC 19) if a Device password is generated you are presented with a pair of login/password. Enter generated login in NCLOGIN and password in PASSWORD into your 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).
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
- When a contact is delete from Ubuntu Touch using the native Contacts app
syncevolutionwill 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. - Even after a calendar has been removed it will still show up as an available calendar in the Ubuntu Touch native calendar app.
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.
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.
