So a follower here graciously offers me a script to try to deal with a pdf printing issue I mentioned. And good 'ol "convert"/ImageMagik throws a "not authorized" error. So I look around and find a rabbit hole of crap about remote execution bugs and workarounds and profile files and other related stuff going back at least to 2018, and supposedly fixed. Or not. THIS is why Linux will never be a mainstream desktop. Jeez. And convert still doesn't work.
