I think apt-file added extra repos

I was looking for a way to find the contents of an apt package and I found a post that advised to use apt-file. I installed using:

sudo apt install apt-filesudo apt-file update

This update took ages and some of the packages are quite large. Now even when I use sudo apt update there seems to be additional repos that were added when I installed apt-file.

I think from Get:13 to Get:26 are new and were added when I installed apt-file. And some of them are quite large (ie. 128Mb).

I was instructed to use apt-file as follows:sudo apt-file list freecad

but when I run that command I get the message:

$ apt-file list freecadFinding relevant cache files to search ...E: The cache is empty. You need to run "apt-file update" first.

even after I just did an update with sudo apt-file update

How do I undo all of this? I don't really care about getting apt-file working. I would be happy just removing it and getting rid of these extra repos.

I'm using PopOS 22.04 LTS
