I have been using Kali as my main system since the 2016.2 release and have always made an effort to resolve any issues that have already caused me but this time I need your help. In fact, I decided today to update the 2017.2 version that I was using to the most recent version (2020.2) and everything went well except that since I can't manage to install anything either on my system I always get the error
user @ user: ~ # apt install kali-desktop-xfce
Reading package lists ... Done
Building the dependency tree
Reading status information ... Done
E: Unable to find kali-desktop-xfce package
and when I try to reinstall an already existing package, I get the error
user @ user: ~ # apt reinstall blender
Reading package lists ... Done
Building the dependency tree
Reading status information ... Done
Reinstalling the blender is impossible, it cannot be downloaded.
0 updated, 0 newly installed, 0 to remove and 3 not updated.
Here is the only line present in my sources.list and it is with it that I always worked.
deb http://http.kali.org/kali kali-rolling main non-free contrib
I do not understand how to solve this problem. Need help
