gnome-calendar doesn't sync Google Calendar Ubuntu 20.04

Question

After upgrading Ubuntu to 20.04, gnome-calendar doesn't show the events in my Google Calendar, gnome-contacts does show the contacts which I have in Google services.

• Release: Ubuntu 20.04
• Package: gnome-calendar 3.36.0-1

Answer 1

I've installed calendar via snap (Ubuntu Software) and it didn't work, so I've removed it and installed using apt and it works (there is gnome-calendar 3.36.1-1 in apt repo).

Use the following commands in terminal:

sudo snap remove gnome-calendar
sudo apt-get install gnome-calendar

Answer 3

I tried uninstalling and reinstalling the gnome calendar from the terminal and it still did not sync. I had to remove my Google account completely in settings and add it again. When I brought up Calendar it synced again.
