I finally did and installed Ubuntu 22.04 with almost no problems.  There is some incompatibility with some apps, but overall the process was quick and easy.  By the way the new version has certain advantages and I think it's worth doing.
I have Ubuntu 20.04 pre-installed on my Dell XPS 13 laptop.     I would like to know if an upgrade to Ubuntu 22.04 is possible now.    This latest version is LTS, so it is supposed to be accepted by Dell.       I would also like to know what is the best way to do it.
