I guess he wanted to upgrade to the newly released 22.04, am I right? upgrade is temporarily disabled due to some bug they're sorting out. Guess he didn't read the release notes and did a full reinstall out of frustration. https://discourse.ubuntu.com/t/jammy-jellyfish-release-notes...
I haven't used Windows since 2005, so my opinion might be unwarranted, but I've been upgrading my home Linux distro since sometime before 2010 without a clean wipe. During that time I've heard of so many Windows "fix it by reinstalling" stories that I wonder if that is simply the default first step in Windows troubleshooting. After turning it off and back on, of course.
in the old days I would format before upgrading osx. if you use a bunch of developer tools, they would often break with osx versions. remember macports?
wiping every year or so isn’t a big deal when everything is in the cloud. haven’t needed to in years, though
