How to Easily Purge Unwanted Repositories in Linux

That means /etc/apt/sources.d can get pretty crowded and the apt update process becomes a bit sluggish. Or worse, repositories can become broken, bringing apt update to halt. Because of this, I try hard to keep those repositories to a minimum. One way to do this is to simply open a terminal window and comb through that directory (deleting any unnecessary .list file).
