I upgraded the Ubuntu to 20.10 Groovy Gorrila but a little mistake on the title I think…
# um, perhaps previous installation was not completed so says 20.04 where it supposed to be 20.10
idk
# Ubuntu 20.04 is out! upgrade now

if you are on Ubuntu, run Software Updater. make sure the distro upgrade notification set to any new version instead of LTS, unless you wanted to jump only to another new LTS (Enterprise configurations e.g.)
