Sync fails because of "Couldn't unbind CustomCertService"

cjeudico

Hi there.

I have run into a problem with 2.0.5-ose installed from F-Droid.

I have done the following steps:

Ran DAVdroid < 2.0.5-ose (don’t remember the version) for years with a self-hosted Baikal instance.
Turned off the Baikal instance.
Exported all calendars to .ics-files using the app “Calendar Import Export”
Removed DAVdroid from phone
Created an account at posteo.de
Installed DAVdroid 2.0.5-ose on phone
Created calendars on posteo.de
Logged into posteo.de account in DAVdroid 2.0.5-ose
Set all sync intervalls to 60 minutes and set to sync all past events
Enabled logging to external file
Imported .ics-File with about 1300 entries to a posteo.de calendar using the app “Calendar Import Export”.
Start a sync in DAVdroid settings
Wait
No events appear in posteo.de web interface
Look inside external log file.
Find the following entries in the log file (see end of post). (I have anonymized the log and removed a lot of info. I am happy to submit the full anonymized file via a private message or the likes):
Remove DAVdroid 2.0.5-ose and install DAVdroid 2.0.3-ose
Remove all calendars in posteo.de
Redo steps 7-13 with DAVdroid 2.0.3-ose
Events appear in posteo.de and are synced properly.

Unfortunately I won’t be able to test further, because 2.0.3-ose is working and I don’t want to mess with the now working setup.

I’m curious to hear your thoughts.

Thanks for the great work, btw, I appreciate it!

Update:
I have now run into the same issue on 2.0.3-ose!
The sync ends with the message " Couldn’t unbind CustomCertService"

Does not seem to be a bug that was introduced between 2.0.3-ose and 2.0.5-ose.

I can import the .ics-file to a local Thunderbird calendar without problems.

If I create a posteo.de CalDav calendar in Thunderbird and then import the .ics-file, the import fails for 51 entries.
So it seems like the problem is not related to DAVdroid but to posteo.de or my .ics-file.

However the error message DAVdroid produces is not very helpful

cjeudico

I’ve been able to figure out why the import in Thunderbird failed for the 51 entries:

If the UID of a VEVENT contains “@domainname.tld” or “@machine-name”, the Posteo.de CalDAV server returns HTTP statuscode 404 for the REPORT HTTP method.

I have now removed all occurences of “@followedbyastring” and successfully imported my .ics-file with Thunderbird.

I have not tested the import on my phone using DAVdroid and Calendar Import Export.

Should Posteo.de support occurences of “@followedbyastring” in a UID?

If I have time to do so, I will report this issue to Posteo.de
But please: Feel free to test and report the issue to Posteo.de

Sorry for the noise, I initially thought this was a DAVdroid problem.
