looks like you manually added an Ubuntu repository to your system. Something not recommended as DietPi is based on Debian. You would need to check if the repository is still needed or if it can be removed.

Ah yep. I think this was recently when I was trying to get game emulation working on Kodi which was unsuccessful.

How would I go about removing it as a repo?

It depends.
Can you have a look into /etc/apt/sources.list.d if there is a file inside for the Ubuntu repo.

sudo ls -la /etc/apt/sources.list.d

If yes, just remove it sudo rm /etc/apt/sources.list.d/name.list (replace name.list with the acutal file name)
If there is no file, do:

sudo nano /etc/apt/sources.list

and delete the entry there.

5

another option is to create an overview of source files as follow

for i in /etc/apt/sources.list{,.d/*.list}; do echo "$i:"; cat "$i"; done

Just pick the one in question and remove it.
