See, this is the beauty of running Debian stable as your daily driver. I’ll be on Gnome 43 for two more years, so by the time I upgrade to Gnome 45+ extensions should be compatible. Only half-joking, I really do avoid a lot of early adopter regressions and breakage.
Ubuntu 9.04, because of WUBI (anyone remember that?). Unstable as hell, but allowed you to run a near bare metal Linux install without the hassle of setting up dual-booting and a separate partition. Liked Ubuntu it so much that I soon replaced Windows completely. Currently running Debian, so I haven’t strayed far from the family.
