Canonical releases an Ubuntu LTS release every two years: active is 24.04, next is coming in a few months as 26.04.

LTS support runs for 5 years (there is extended support for 10 years available), so you can skip an LTS if you don't need the latest base software.

You are right, I got that mixed up. To be fair, I somehow also thought of yearly releases for Fedora, which isn't the case. It's every six months, so the relation remains identical, just off by a factor of 2 :D
