@deathkitten Thank you. Adding to this. Many of us tech-noobs would like nothing better than a switch, but the institution we work with does not support much less effectuate a switch. There is some element of agency in this. I cannot switch on my own, but I can and will put pressure on my institution to enable and support switching.

@zillion Cool - good to know, appreciate the advice!

@jonw Well someone pointed me to use do-release-upgrade -d, appearantly because ubuntu do not see the 25.10 version. Then it worked. But why not mention that in the documentation, and various webpages instcucting how to upgrade? Searching the web for "how to upgrade kubuntu to new release" did not lead me to any page (that I read) containing the required information, neither did links included in the release announcement.I last used *ubuntu probably more than 20 years ago, revisiting now in the hope that it would be a user friendly experince, ironically.

@fritjof @mosgaard ja, luanti er ret fedt. Tror jeg. Jeg har aldrig selv været optaget af at spille computerspil, men jeg synes det er sjovt at programmere. Har lavet en mod hvor man kan undersøge og bygge på Horne Land og Svanninge sogn. Tjek gerne mit spil ud her: https://luanti.denfjerdepart.dk/

@synduckate I saw someone mentioning Joplin, that I'm not really familiar with. But that did look like a more kinda 1:1 replacement.Hope you find something useful that works for you!
