what frankendebian is that you're calling ubuntu-like 20.04 (focal fossa) that is trying to deliver a base-files version greater than 12 ?!
on 20.04/focal this should/must be 11-something, matching a debian 11 base system level (aka. "bullseye")...
otherwise you're left to either force the package installation, if that's possible disregarding its "depends:" clause, or upgrade to 22.04 (jammy) where qt6(-qpa-plugins) is already available.
byee
ps. again, i'm no debian/ubuntu expert, just giving you some feedback and possibilities :)
