@Mr-dot-lu
I would recommend to try the updated release, link below:
https://github.com/polycube-network/polycube/releases/download/v0.9.0/polycube-v0.9.0.tar.gz

launch the automatic install script, after extracting the tarball (use -h to see the different installation modes)
./scripts/install.sh

The command issues is wrong. You should install using ./scripts/install.sh, not ./install.sh.
Documentation has been checked; the reported command there is correct. So, closing the issue.
