Ubuntu 8.10 in early 2009, after Windows Vista otherwise bricked my laptop. I’ve distro-hopped on a few occasions but most of my 16 years of Linux have been on Ubuntu. That said, I moved away from Ubuntu after a failed upgrade to 22.04 LTS, to OpenSUSE and then to KDE Neon, now I’m on Nobara and couldn’t be happier.
