I have Gnome Calendar installed on Ubuntu 20.04. When I go to default applications under settings, I can not set Gnome Calendar as the default application. Text editor is the only option that I can select. Is there any way to make Gnome Calendar the default?
The solution here seems deprecated in Ubuntu 20.04 and no longer applicable How to set gnome calendar by default
gedit /home/yourname/.local/share/applications/mimeapps.list
