In Ubuntu 22.04, when I do gio mount google-drive://<my email> I get "volume doesn’t implement mount".
I used the Online Accounts Settings dialog to log into my account, I have gvfs, gvfs-fuse, gfvs-backends and ran the daemon, I tried to use dbus-run-session.
In my other laptop, a 20.04, the mount works fine. Not sure where the difference lies.
Turned out this is because my terminal is a Flatpak package and Flatpak sets GIO_USE_VFS=local which is passed to the terminal and to my shell. Unsetting the value in my .zshrc fixed the issue.
