I have an Ubuntu phone and it use syncevolution as backend for the contacts. I use command lines to have my CardDav contacts on my phone. But since I switched from self signed certificate to letsencrypt (related or not), I have tons of errors.

$ syncevolution owncloud contacts

Doing a slow synchronization may lead to duplicated items or

a different synchronization mode may be the better alternative.

Doing a slow synchronization may lead to duplicated items or
lost data when the server merges items incorrectly. Choosing
a different synchronization mode may be the better alternative.

So I decided to try some things I don't remember exactly (like forcing sync with refresh from local/remote) and changed the end of previous log by:

First ERROR encountered: local, status 20048

Then:

Data modified @default during synchronization:
*** @default/calendar ***
Comparison was impossible.

Since this step, I'm not able anymore to delete contact from my phone and make it sync on the server (to delete the contact on the server itself), instead the contact is just "cleared" (any information disappear but the contact is still here and keep firstname and lastname). I can sync contact created on the server on my phone and send contacts created on my phone on the server.

It seems the backup database is corrupted but I'm not able to reset completely my config. I just wanted to start by zero but I can't find any way to do this. :'(

It's a real shame that Ubuntu Touch never really had a built-in easy sync for things like Caldav and Carddav. I would love to see ubports or an app developer step up there.

Would it be worth removing the current config and starting again?

syncevolution --print-sessions

and then

syncevolution -remove each one?

Once you have this done you could start again using something like this script which appears to be working for https and might suit you.

    It's not print-sessions, it's print-configs, I deleted the two related to my configuration, restarted to clear the sessions and then added again my notes taken from there influence-pc.fr/… (was working from past 2 years) so just after the first "sync slow" here is what I can see Comparison was impossible.
