I have a problem with the GNOME Shell calendar under Ubuntu 18.04: all my calendar entries (from Google Calendar) are duplicated. Would anyone know why?
Thank you!
One clarification: I linked my Google Account to GNOME, but I also had windows asking for passwords from all my calendars before that. When I suppress my Google account, the problem does not appear anymore. So I think it's the ICS that I had previously imported into Evolution. But even after removing .local \ share \ evolution \ calendar \ system \ calendar.ics, the entries are still present.
