So I've ran a sudo apt update and got some errors:

N: Skipping acquisition of configured file 'main/binary-i386/Packages', as repository N:

I've searched for information on how to remove that repository but haven't found any clear answer

When I try to remove the GPGkey I get "no data found" so can't delete they key also. Does anyone know how to get rid of those errors?

  1. ls /etc/apt/sources.list.d/

Look for the name of the repo you want to remove, or if you're unsure, open the file with any text editor, if it mention the name of the repo you want to remove (in my case it has 'packagecloud.io' and 'git-lfs') then you should be good to go

  1. rm /etc/apt/sources.list.d/<insert file name here>

hope this helps
