I even tried to wget the nsenter from pypi repository https://pypi.org/simple/nsenter/ and used to install:
python setup.py install
The README.rst says:
Requires Python 2.6 or higher
But for installation it uses only python3/pip3:
Install from PyPI::
sudo pip3 install nsenter
Install from git source::
python3 setup.py install
Any ideas how to install nsenter without having to change my python version? Maybe this could be a bug that needs to be opened upstream?
The issue was something related to the infrastructure! I needed to add --mtu=1450 to my docker service because probably some dependency from nsenter needed bigger packets... Now it runs successfully!
