Errors Bootstrapping Ubuntu 20.04

Fresh install of Ubuntu 20.04. I apt-get install git and cloned cerbero. First error running ./cerber-uninstalled bootstrap is no module named setuptools. I don't have an exact stack trace of that I'm afraid.

I then ran apt-get install python3 python3-pip python3-setuptools and added an alias for python=python3.

Now when I try to bootstrap I receive the following:

trms@cbl-cg:~/cerbero$ ./cerbero-uninstalled bootstrap
Install prefix will be /home/trms/cerbero/build/dist/linux_x86_64
