Sources.list for Debian 10 Buster

Please edit your /etc/apt/sources.list , remove the contents from it and include just the below lines.

deb buster main contrib non-free
deb buster-updates main contrib non-free
deb buster/updates main
deb buster-backports main contrib non-free

Note that this use case covers almost every safe way of installing packages in Debian.

  1. non-free is needed for proprietary drivers
  2. backports are for fresh new stuff which might not be covered or old
  3. buster-updates covers new updates for buster :tada:
  4. Don’t forget to do an apt-get update after changing the file.
