Dropping Snap support on Linux Mint 20 forces me to consider Linux Lite 5.0 as a preferred choice of light weight clone for Ubuntu 20.04. Snapd daemon could be installed on Linux Lite 5.0 with no issues. So Gnome 3 Desktop installation might be done via “sudo snap install” as quite straight forward procedure.
