That's a waste of time. A tormented 30 minutes rant.
The Ubuntu install was just fine, except the snap repos application. That window was not populated with packages by categories, and doesn't show any feedback,while installing something, maybe a bug, I don't know.
Then he starts a snap install, then seconds later he starts another snap install for the same program, the GUI tells him it can not do the second install because it's busy with the first install that was still in progress. He doesn't bother understanding the message or even reading it, let alone looking up for its meaning.
Other than that, nothing looked different at Ubuntu, same like in the last 3 years or so, except this time the installer can install on a ZFS file system, and the apt does automatic ZFS snapshots at install, which is great.
