I tried to upgrade from Ubuntu 20.04 to 21.04 but it did not work. I first ran the following:
sudo apt update
sudo apt dist-upgrade
sudo shutdown -r now
after restarting, I still had 20.04.
I tried manually from Software & updates, it shows an upgrade available
but when I press OK, no other windows show up. On terminal I got:
$ sudo apt update

Checking for a new Ubuntu release
Please install all available updates for your release before upgrading.
What could be the problem and how can I solve it? Shall I remove these files that are still pending? What command shall I use?
Thank you
