I managed to trash my sources.list and its backup file...
could someone please post theirs or point me to where I can find an official list so I can put everything back together please
This is more of a curiosity question as I try to get a better understanding of apt and package management.
I'm seeing that in my /etc/apt/ and /etc/apt/sources.list.d/ folders I have very or sometimes identical files which have the extension of sources.list, sources.list.distUpgrade, sources.list.save, and so on.
What's the point of these duplicate or similar files?
