20.04 and 22.04 were LTS versions, aka, long term support.
Any application that requires stability should run on LTS versions. Combined with Ubuntu being one of the most popular distros, makes 20.04 and 22.04 the most popular choices for anything in a home lab and many smaller business needs.
Whether you’re building a server for home DNS, or a time server for a small business, then you’re probably using Ubuntu as the base.
I think the next LTS version will be 24.04, so things might shift sometime after that.
