Spent two days on the next challenge: "Jammy Jellyfish", which funny name stands for version 22.04 of Ubuntu, the OS under which our servers run, both the Home server and the VPS. Version 22.04 was officially rolled out last month, and then this retired IT professional started to itch. Jammy is officially out of beta so we can think about upgrading, right?

The most important aspect of such a challenge is that our panel manager, Virtualmin, does not yet support Jammy or, as it is officially called: does not yet offer a Jammy version of the necessary packages. But they do offer the chance to manually upgrade Focal, or version 20.04, to Jammy. And I just tried that. But too much went wrong. The new OS was installed without any problems, and Webmin also came into the picture just fine. After that, you have to install the various packages that make up Virtualmin yourself. And that went well, but not smoothly. Apache2 in particular took a lot of effort... Finally spread the Virtualmin module over everything, and it ran... a bit. But the integration didn't get going and getting an SSL certificate didn't work at all.

So I opted for option B: installed Focal again, then the automatic installation of Virtualmin, with all the extras such as Samba, and finally upgraded the server thus obtained with do-release-upgrade... Gradually you discover that this is not supported until August next, but it's running. Hip hay!

The home server is now fully and officially running "Jammy Jellyfish", and no longer "Focal Fossa"! The VPS is also waiting for such an adventure, but with that, I really wait until August.
