Ethan Great job! Thanks. Just to clarify the source of the problem: If I take your example Qt6Core.pc, I can find this in the Debian packages (https://www.debian.org/distrib/packages) but searching for the same file in Ubuntu (https://packages.ubuntu.com/) fails to find the the .pc file. The file list for the Ubuntu qt6-base-dev package doesn't contain any .pc files, that I can see. So that suggests that the problem lies in the Debian-to-Ubuntu step, not the Ubuntu-to-Mint step. I mention this because, AFAIU, Mint pull most of their stuff directly from the Ubuntu repo. So I am thinking that I ought to raise with Ubuntu, not Mint. P.
