unable to install pythia8

Never seen that,

Looks like HEPMC can not compile on your system.
It says that it cannot detect your system.
What is your OS and what is the type of hardware that you use?

I do see newer version of HepMC2 available (2.06.11 is released).
So maybe you can check if installing that one fix the issue.
If not you might need to ask HepMC author how to solve this.

Thank you Olivier.

I'm using Ubuntu 20.04 on parallel desktop on my MacBook Pro.
Would you mind telling me how to select version of hepmc2 while installing it on madgraph.

Thanks Olivier Mattelaer, that solved my question.
