Many people break their Kali Linux installations by following unofficial advice, or arbitrarily populating their sources.list file with unneeded repositories. The following post aims to clarify what repositories should exist in sources.list, and when they should be used.
Any additional repositories added to the Kali sources.list file will most likely BREAK YOUR KALI LINUX INSTALL.
Regular repositories
On a standard, clean install of Kali Linux, you should have the following two entries present in /etc/apt/sources.list:
deb http://security.kali.org/kali-security kali/updates main contrib non-free
You can find a list of official Kali Linux mirrors here.
Source repositories
In case you require source packages, you might also want to add the following repositories as well:
deb-src http://security.kali.org/kali-security kali/updates main contrib non-free
Bleeding Edge repositories
If you have a need for bleeding edge repositories, you can add the following entry. Do not add this repo “for the heck of it” – it’s called “bleeding edge” for a reason. Packages in this repository are NOT manually maintained (they are auto-generated), and are low priority in general.
#deb-src http://repo.kali.org/kali kali-bleeding-edge main
