Nah, if you’re on LTS, the recommended upgrade is at XX.04.1, which typically comes around July. And 22.04 doesn’t go end of life until April of 2027, so there’s no mad rush to upgrade if you’re happy.
If you don't already see a reason, you probably don't have one, especially for a server. Especially if you sign up for the Ubuntu Pro free tier, you have 10 years to come up with one. 😂
