I'm not sure if you removed the actual repository and replaced it with a custom one, but the first one (assuming that's what you have set up) is not a real repository.

You can remove the repository in one of the following ways:

  • software sources
  • removing the line for the repository from /etc/apt/sources.list
  • if it's not in the above file, look in /etc/apt/sources.list.d directory for the ppa and remove the appropriate file (you could use the rm command to remove a specific file, but be careful not to delete something you don't want to delete... if you're new, create a test directory and try using the rm command to delete files from it to verify you don't delete the wrong thing, also avoid using sudo when practicing the command to avoid removing important files)

As for the security related issue, I'll need to know which version of ubuntu you have (I'll edit the answer accordingly)
