Also, Linux is bullshit as you can't do a thing because it wants version XX.X and your distro only has AA.A in the repo so you have to compile it yourself and it doesn't install properly for your distro so the system acts as if it doesn't exist at all...
Either that or the devs thought the program shouldn't install at all for some shitty reason and you need to also figure out what files need to be copied to where.
