Then I’d definitely set up a test system in a VM on your own PC (I.e. not the actual server machines). Even if you don’t want to use Docker, you can set up a complete version of your new server and practice deploying Jellyfin and Plex, and then test accessing it “remotely” to manage it. You can then decide whether switching away from Win11 is worth it.
If you’re not familiar with the process of setting up a linux server then I’d actually suggest Debian instead of OpenSuSe. Looking at the Jellyfin guide for example it specifically covers the steps for installing directly onto a Debian host (while OpenSuSE set up means using the Fedora RPM guide). There are also straight forward guides for setting up a Debian server.
Personally I’m not a fan of Ubuntu (because of Canonical and Snap etc) but there may also be a good choice just because there are so many guides out there for setting up Ubuntu server.
Its a fascinating election when you look at the stats. Labour vote share barely changed, Tories collapsed and Reform took most of their votes. In many of the conservative constituencies lost the Tory + Reform vote combined would have won.
Of course the Tories will make the mistake of trying to be more like Reform or even merge with them. That will be a huge mistake and they will probably turn off their remaining core vote.
This is really just another example of how broken the first past the post system is. I’m glad labour won but they’re kidding themselves that they somehow broke through to the public - they benefited from a split rightwing vote, just as Boris Johnson benefited from a split remain voter base when he won his big majority with just 43.6% of the votes in 2019.
Labour won a huge majority with just 33.7% of the vote! Only 1.6% higher voter share than in 2019 and way off the 43% Blair got in his landslide election in 1997.
