Death is Coming for Ubuntu 22.10 – Upgrade Soon!
Those without a calendar to gawp at should know that this is less than a month way away at the time of writing.
But don’t panic (though I admit my headline doesn’t help in that regard).
You can upgrade to Ubuntu 23.04 in-place, without needing to reinstall from scratch. Barring the 25 mins or so the process takes, it’s a painless procedure (note: you may need to manually re-enable any PPAs or 3rd-party repos you make use of, but that’s true of any upgrade).
Support for Ubuntu 23.04 ‘Lunar Lobster’ ends in January of next year. This might be a little sooner than you want given, y’know, you’ve only just made the move on up to it.

Ubuntu 22.10 EOL Is Coming Soon
On July 20, 2023, Ubuntu 22.10 (Kinetic Kudo) will no longer be supported. Users of that release are encouraged to either upgrade to the next non-LTS release (23.04) or do a fresh install of the latest LTS release (22.04.2).
One thing to keep in mind is that the latest non-LTS release (23.04) is only supported through January 2024. But that's the way of the Ubuntu non-LTS releases. Because of that, it might behoove you to migrate to the latest LTS release, which enjoys support through April 2032.
