Not at all a specialist, but tried to install Waydroid on LL, Linux Mint and Zorin OS (all forks from Ubuntu) and failed. There's probably something I miss or fail to understand, but so far no luck, and just right now I have not enough time to give it another go.

Waydroid only works in Wayland, and none of the OSes mentioned (or rather the DE they use) support Wayland right now. You have to use either Gnome or KDE.
