Installing Tutor breaks at collecting mypy

Dear reader,

I try to install OpenEdx via tutor on an Ubuntu 22.10 server. The installation with the command pip install "Tutor[Full] stops after collecting mypy. The terminal gives the folowing output:

pip install “tutor[full]”

Collecting mypy

I try to install within an virtual environment, but also outside the environment the same error occurs. I use Ubuntu 22.10 as a root user.

I hope anyone can help me with this issue
Thanks a lot in advance!
