I feel the pain.

Then again, I built and ran "Linux From Scratch" once, so maybe I'm a masochist.

If Pop OS has all the required build tools (looks like they do) and packaged libraries (probably), you should be able to plonk the source down in your /opt folder, build the TB binary in place, then just run TB from there without messing up your package manager.

I currently do this for FreeCAD, because Devuan's packaged build is ancient...
