Now my Ubuntu version is 20.04.1 LTS which is focal so I'm wondering firstly why are there eoan related repositories? Secondly, how would I go about fixing this error. I had eoan before as the first linux distribution I installed on my machine which I then updated to 20.04.

Any help would be appreciated.

During a correct upgrade procedure, the eoan get replaced by the focal upgrades. My guess is (1) you didn't use a standard Ubuntu upgrade procedure, or (2) you re-added them yourself post-upgrade because you wanted a package that isn't available any longer in 20.04 (a number of things have now gone EOL in 2019, python2, Qt4 etc but I'm using them only as example). I see it only as user done; someone with sudo rights, I'd just remove the eoan sources (rather than re-point them at old-releases) — guiverc, Jan 10 '21 at 04:21

The simplest way to resolve this would be to remove "eoan" repositories from the updater.

Open "Software & Updates"
Uncheck unnecessary repositories

Software & Updates

From here apt will update itself and you should be good.
