Right, I messed up. The LTS versions actually have 3 years support, but it's still less than the 5 years I can get out of the main Ubuntu distro. (And this is confirmed
here.)
It's not just printing, so many things have been messed up, for
years. Audio, function key buttons, fingerprint readers, USB modems, and especially video cards all have major problems inside their open source driver implementations.
You can just install Xfce on Ubuntu and still get 5 years LTS, right? The few GB size difference for having some unused software on your system shouldn't matter compared to the size of the blockchain.
Correct, but as you can see in the link I shared,
all packages in the repository called
main are supported for 5 years. XFCE Desktop is not inside that repository, so it gets support for 3 years.
