Thanks for replying, sounds like a good idea to use 20.04 but for some reason there are no desktop release for 20.04 and Ubuntu only have the server version for 20.04 which has built-in SSH server included in the distro, which mean the savvy use of UART Serial is not required for a headless install.
Since ubuntu only have 20.04 server release for the Raspberry Pi, it also means I have to go through the hassle and wait long times for manually installing the desktop environment downloading via internet.
Would happen to know if I might be able to manually change, modify, remove or set a "login" and "password" credentials for the Ubuntu installer?
