you mention as not helping... ie. read the output it gives you & ensure there were no warnings, errors, missing lines, extra/contradictory lines etc.. however you're off-topic here now, with 20.04 the oldest standard support release of Ubuntu that is on-topic on this site. – guiverc Jul 03 '23 at 03:04
