Remember that the sources ("deb-src" lines) are only needed if you want to download the original debian sources tarball(s) for a package - usually developers would be interested in this, and if you don't need it, these lines double your index files downloads, slowing your system updates. > deb http://security.debian.org/debian-security testing/updates main My stretch line for security looks like this: deb http://security.debian.org/ stretch/updates main "testing" does not have security updates, so you will need to comment out all your security lines... if you need security updates, use stable. > #deb-src http://security.debian.org/debian-security stretch/updates main > deb-src http://security.debian.org/debian-security testing/updates main > > # stretch-updates, previously known as 'volatile' > deb http://ftp.es.debian.org/debian/ testing-updates main > deb-src http://ftp.es.debian.org/debian/ testing-updates main You need to also comment out "updates" lines - they only apply to stable distribution. > deb http://httpredir.debian.org/debian/ testing main contrib non-free That looks like an error line. You can add "contrib" and "non-free" to the lines near the top though, to add those parts of Debian if you decide you can stomach the non-free'ness etc... > but Synaptics reports different repositories: > https://www.dropbox.com/s/spwovspzu6hqrvp/Screenshot%20from%202018-07-04%2007-42-42.png?dl=0 Synaptics suggestion might be correct. But have a look here to be sure: https://wiki.debian.org/DebianTesting Good luck :)
