Hello, this is my first post...
When I try to upgrade my system using apt-get upgrade (after apt-get update) i get the following error:

Code:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 clang-6.0 : Depends: libgcc-8-dev but it is not installed
 gcc-8 : Depends: libgcc-8-dev (= 8.2.0-7) but it is not installed
 libobjc-8-dev : Depends: libgcc-8-dev (= 8.2.0-7) but it is not installed
 libstdc++-8-dev : Depends: libgcc-8-dev (= 8.2.0-7) but it is not installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
When I then try the suggested command apt --fix-broken install I get the following output:

Code:
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Correcting dependencies... failed.

E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.
E: Unable to correct dependencies
I have tried multiple solutions I found on the internet but none of them worked for me.
Here is some information on my system:

Description: Kali GNU/Linux Rolling
Release: 2020.4
Codename: kali-rolling
Kernel: Linux 4.18.0-kali2-amd64
Architecture: x86-64

I hope someone has an idea on how to fix this
