[Freedombox-discuss] Radicale stopped working.

[A. F. Cano]

I cannot synchronize from either the phone or the computer.  Korganizer, after
an "akonadictl restart" says:

log_davresource: Unable to fetch collections 600 "There was a problem with the request.\n" (500)."

>From the phone: (DAVDroid debug info)

HTTP RESPONSE:

Since I've recently read that radicale had an issue, I've waited to be sure
that plinth 19.1 was installed and even rebooted the FreedomBox.  Previous
to that I had to do a manual upgrade of radicale (via aptitude) since
automatic upgrades refused to do it due to config file changes.  The only
difference (besides comments where spaces have been removed) was a FreedomBox
specific line at the end.  I chose to keep the FreedomBox-modified file.
I don't remember which file it was and now I can't find it.  It's not the
config in /etc/radicale.

In /var/log/uwsgi/app/radicale.log (on the FreedomBox) this appears:

[7fda9da86780] ERROR: An exception occurred during REPORT request on '/<user>/calendar.ics/': Failed to load item 'KOrganizer-1994310660.776' in '<user>/calendar.ics': can't compare offset-naive and offset-aware datetimes

I've replace the real user name above with '<user>'.

Any idea what might be the problem? Any hint as to anything to try?

Thanks!
