I'm trying to install Openstack on Ubuntu-18.04 LTS using devstack and ./stack.sh fails with below error.

Tried to pip install setuptools and pip install --force-reinstall --no-deps setuptools==59.6.0 but couldn't help.

What I'm missing to complete the installation?

Answer 1

The following example shows the command for installing the OpenStack client with pip, which supports multiple services.

 pip install python-openstackclient

The following individual clients are deprecated in favor of a common client. Instead of installing and learning all these clients, we recommend installing and using the OpenStack client. You may need to install an individual project’s client because coverage is not yet sufficient in the OpenStack client. If you need to install an individual client’s project, replace the PROJECT name in this pip install command using the list below.

 pip install python-PROJECTclient

Please find more information on here about installing the OpenStack on Ubuntu or other OS.
