There is one remaining piece of software I can't get installed (and also can't find a workaround for), with the upcoming display out it would be a nice to have even if it is a bit niche. Universal Radio Hacker.
Dug into the issue again recently and found the root cause. libqt5gui5t64 is a dependency and only in the trixie testing repo, but after adding testing it still can't be installed because it conflicts with libqt5gui5-gles which is installed.
Didn't feel like breaking and reimaging my FLX1 by removing libqt5gui5-gles. So I was wondering if there are any ideas to get it installed
I realize this is nearly a year old so I hope you've found a solution. I wonder if you could decompress the URH deb, change the dependencies to allow either libqt5gui5*, repackage the deb, and install it that way.
