I have so many problems with my calendar (most annoying one at the moment are unstoppable reminders which just appear on my device, not on that of my girlfriend), that i want to try to purge it completely (with any config files) from the device and reinstall it again. Is there a way to do this?

I already tried to just reinstall the app, delete calendar database, delete the sync accounts and build them up again. So it's my last hope to solve the problem without resetting the complete device (which I really don't want to). The calendar app is one of the most important functions for me and i'm absolutely frustrated meanwhile.

I think the 'undead reminders' problem is something that was introduced into SFOS with version 2.1. It seems to be tied to recurring events, but independent of the remote calendar backend/account type (although I have no reports of this phenomenon with an EAS backend). In my personal case, the reminders pop up on every non-SFOS client, and I end up deleting those past events to get rid of the notifications. Bad.

Perhaps @chris.adams has an idea about the roots of this annoying bug. Re-creating the whole calendar only helps a couple of days, if at all.

Finally I found a rather simple way on how to reset all alarms in /home/nemo/.timed/events.data. I'm pretty confident that this will remove all stale calendar alarms:

After (backing up &) removing all calendars via the accounts page in setting and removing the files /home/nemo/.local/share/system/privileged/Calendar/mkcal/db and /home/nemo/.local/share/system/privileged/Calendar/mkcal/db.changed, login to shell via ssh or terminal an type: timedclient-qt5 -c

This will delete all alarm entries. Now reboot, recover your internal calendars an recreate remote calendars.

Thank you very much, working ! NB : be careful, ,command is timedclient-qt5 -C ( with capital C )

cd /home/nemo/.local/share/system/privileged/Calendar/mkcal/ und Enter

Dann den Kalender öffnen, damit die Dateien neu erstellt werden.

It would be nice to write your contributions in English so that everyone can benefit from your knowledge.

As far as I understand @Fellfrosch he already deleted the database as you described. The problem I have since deleting all calendars and database I also get old event notifications, especially olf recurring events. I don't know where those notifications are stored and how to delete them.

@peter-berlin: I've written, that I deleted already the database and also I don't have any google account. @jollajo: that is a good guess, that these are old reminders from just deleting the database. I've done that a lot of times, because I also suffer from calendar duplications. So maybe we just have to find out where the reminders are stored. Will have a look on that.

Fellfrosch ( 2017-07-22 14:12:31 +0300 )edit

It seems that the event reminders are stored at:


I'll try to delete(rename) that file + my caldav accounts + the calendar database. Than create everything again. I will report here, if it has any impact.
