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...
I refuse. I hate this. The stupid pop_os installer isn't working correctly. I'm... Kinda tired of pop and this might cause me to nuke everything and go back to mint.
That will work, too...
It's a lot more work since I need to figure out WTF to back up. There's a lot of dead digital junk on my laptop at this point.
Ha! I know how that is! Years ago I built a 1TB encrypted RAID array to be my digital sock drawer. I resist every temptation to expand it, instead going over it and deleting stuff whenever its getting full. Tedious - but very necessary for me...
