Timely but I dare ask: I need to rework my thinkpad, still in good shape but with an older ubuntu distro. Reasonably fluent linux user but not expert, primarily dev workflows - what's the recommendation?
- Before 35: Mostly ubuntu, latest version (install after a couple of months of general availability)
- After 35: ubuntu LTS versions (install after a couple of months of general availability). Since 16.04 I've been on LTS only; should have done that earlier.
unless you really need a very new version of a piece of software, the safest bet will always be the latest LTS version of Ubuntu. You could perhaps just upgrade your laptop OS with the software package GUI?
Fun fact: You don't really need to install any of the "flavors" of Ubuntu to get the various desktop environments (KDE, GNOME, Cinnamon, etc.), you can just install them as a package! (`apt install kde-full`). You can switch between them when logging in.
