Alright, it wasn't that hard. I just cloned the source code from a mirror, make'd and make install'ed:

  1. Clone Git repository of afl, I use a mirror I found on GitHub:

    git clone https://github.com/mirrorer/afl
    
  2. Change directory and make and make install:

    cd afl
    make && sudo make install
    

Of course, there might be some libraries you need to install in order to compile. I did not need to do this.

I just want to add that on Ubuntu 18 you can just install now, but that version seems to be broken.

sudo apt-get install afl

After installing and trying to use afl it seems that it is broken in Ubuntu 18. So you should still refer to vatsug's answer to install.

Apparently it will be fixed in Ubuntu 19.

Blog post about it being broken.

I got an error that said:

Package afl is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'afl' has no installation candidate

On Ubuntu 20.04 (Focal Fossa), sudo apt install afl++ is the right command.
