I used the above solution. Also changed the permissions of ics files in the calendar using chmod 777 * as well as the event-registry.txt file referred to in the previous post.
However, I still get this message in the log.
WARN | Unable to update event (Updated: Lunch )!
User does not have permission to perform this modification. [note that participant overrides not available on recurring events]
Further, only a one way sync from ical to gcal has happened. if i make changes in gcal, they are not reflecting in ical. perhaps due to such warnings as above.
Neither are changes in ical subsequent to the first sync, are refreshing in gcal.
i am starting standalone-start.sh in a terminal window.
any ideas?
Make sure you change the permission of the directory containing the *.ics files and not just the *.ics files themselves. If you create a new event and recursive read/write permissions are not set on the parent directory, you will get an error.
