When trying to install Pypowervm on Ubuntu 18.04 on ppc64le, I get package name dependencies that are not installable.

[upenr]

The following packages have unmet dependencies: pypowervm : Depends: python3-pyrsistent but it is not installable Depends: python3-zipp but it is not installable E: Unable to correct problems, you have held broken packages.
I tried installing pyrsistent and zipp via 'pip3 install pyrsistent zipp', but the error persists.
'pip3 install python3-pyrsistent python3-zipp' doesn't work.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
