I have come back to a computer that hadn't been switched on since March 2022 (1 year), it has Ubuntu 21.10 installed and I'm having difficulty upgrading it to 22.04.
I know 21.10 was an interim release and I'm guessing it's 9 month maintenance period is over.
I have tried both:
sudo apt update
and
sudo apt upgrade
I'm not too surprised the update doesn't work but I'm a little disappointed if this is what is preventing me from doing an upgrade.
Is there a way to upgrade without doing a fresh install ?
I found a page that attempts to help but it was written more than 12 years ago:
https://help.ubuntu.com/community/EOLUpgrades#SpecificOlder
These are the errors I get:
$ sudo apt upgrade

The following package was automatically installed and is no longer required:

Use 'sudo apt autoremove' to remove it.
The following NEW packages will be installed

The following packages will be upgraded:

4 to upgrade, 1 to newly install, 0 to remove and 0 not to upgrade.
