After many (too many!) years of running Ubuntu 20, I finally upgraded to Ubuntu 26. Installation went fine.
What was particularly useful was Claude helping me tweak the installation and UI to my preferences. So many years usually pass between upgrades to a major version that it takes hours to figure our where controls have been relocated to — or sometimes even removed. That kind of knowledge is exactly the kind I want, don’t care how I acquire it, and don’t plan to keep.
