It looks like the Ubuntu system installed python3-virtualenv is acceptable for part of the installation process, but this causes problems later.

Thanks for reporting the problem. At first glance, it looks like a bug in the bundle_installer in that it assumes a virtualenv executable exists under the pip that was installed in the first phase. A solution would be to use the virtualenv that already exists. The problem using a virtualenv that already exists is that it could be really old and thus incompatible with the scripts in this package. Another solution is to insist that virtualenv be install within the new pip regardless of whether it already exists on the system.

For the time being, you can simply run the ebcli_installer.py file in the package using the Python you installed in the first phase:

/home/username/.pyenv/versions/3.7.2/bin/python ./scripts/ebcli_installer.py

Thanks, @rahulrajaram ! I tried that and it ended up hanging at Installing setuptools, pip, wheel... I uninstalled all versions of virtualenv (v16.0.0 and 16.7.5) which were in /home/username/.local/lib/python3.7/site-packages/ and ran the first bundled_installer again. It installed virtualenv anew (this time in /home/username/.pyenv/versions/3.7.2/bin/) and completed successfully.

So there's some discordance between the pyenv managed Python installation and their usage of any system-level installations of Python packages.

That's strange. Did a rerun not fix the issue?

... and completed successfully.

That's great.

Yes, this issue requires a deeper look.
