When trying to update the apt database I get the following:

How do I go about fixing this?

TIA

 

The command to update the apt database is

Code:

apt-get update

, not

Code:

apt-get upgrade

 

Sorry, I copied the wrong thing (I tried that to see if it would help)

 

There must be something wrong with your apt installation. I recommend you use yum then instead of apt.
