I'm on Ubuntu 20.04 with gnome-calendar 3.36.2 and have the same problem: Google calendar did not sync. Then I removed the cache in "~/.cache/evolution/calendar/", and gnome calendar showed no appointments at all (as expected).
Clicking the "sync now" menu item changed the calendar icon briefly to a checkmark, but "journalctrl -f" said: > Feb 08 13:28:20 sybo gnome-calendar[17021]: Error synchronizing client > Feb 08 13:28:20 sybo gnome-calendar[17021]: Error synchronizing client > Feb 08 13:28:20 sybo gnome-calendar[17021]: Error synchronizing client for every calendar, enabled or not. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to gnome-calendar in Ubuntu. https://bugs.launchpad.net/bugs/1866999 Title: gnome-calendar does not sync with Google Calendar Status in gnome-calendar package in Ubuntu: Confirmed Bug description: Since upgrading to 20.04dev, gnome-calendar doesn't show the events in my Google Calendar.
