Correct sources.list for debian unstable I recently started using the unstable debian repo and updated all my packages to the newest versions. My /etc/apt/sources.list looks like this: deb unstable main contrib non-free deb-src unstable main contrib non-free deb buster/updates main contrib non-free deb-src buster/updates main contrib non-free # buster-updates, previously known as 'volatile' deb buster-updates main contrib non-free deb-src buster-updates main contrib non-free Is this the proper configuration for security? I only changed the top 2 to point to unstable instead of buster, as you can see the other 4 sources still point to buster.

You need to edit your sources as follows:


deb unstable main contrib non-free
deb-src unstable main contrib non-free


Debian Sid doesn't have a security repository.
