[Pulp-list] Pulp RHEL8 rpm installation

[Mike DePaulo]

Hi Adam,

I tested this with pulplift and can confirm that the 3.16 repo has this
problem, but the nightly repo does not. (And 3.17 repo doesn't exist yet
for el8 for some reason.)

The installer fails at collectstatic for me ("pulp_common : Collect static
content"), which is where any python dependency errors are usually caught.

These are the vars I used:
pulp_default_admin_password: password
pulp_install_plugins:
pulp_settings:
pulp_install_source: packages
pulp_api_bind: "unix:/var/run/pulpcore-api/pulpcore-api.sock"
pulp_content_bind: "unix:/var/run/pulpcore-content/pulpcore-content.sock"
pulp_pkg_repo: "
https://fedorapeople.org/groups/katello/releases/yum/3.16/pulpcore/el{{
ansible_distribution_major_version }}/x86_64/"
# pulp_pkg_repo: "
https://fedorapeople.org/groups/katello/releases/yum/3.17/pulpcore/el{{
ansible_distribution_major_version }}/x86_64/"
# pulp_pkg_repo: "
https://fedorapeople.org/groups/katello/releases/yum/nightly/pulpcore/el{{
ansible_distribution_major_version }}/x86_64/"

I hope the nightly repo does suffice for you.

I tried to figure out why this occurred, but will move onto other stuff now
(since the pulp project neither supports nor tests the 3.16 repo), and
leave you with what I uncovered below.

Remember that the 3.16 repo has pulpcore 3.3, and we're on 3.6 now, and we
only support 3.6. Although the installer does generally work with a few
older versions of pulpcore, we only test it with the current pulp pypi
release, git branches, and the katello nightly RPM repo. It does not seem
like an installer issue, because I can reproduce it on the command line
with the following commands:

sudo su - pulp --shell /bin/bash

PYTHONPATH=/usr/lib64/python3.6/
DJANGO_SETTINGS_MODULE=pulpcore.app.settings
PULP_SETTINGS_FILE=/etc/pulp/settings.py /usr/bin/python3-django-admin
collectstatic --noinput --link
(this throws your error.)

pulpcore-manager collectstatic --noinput --link
(latter command is equivalent and throws same error)

Both versions of the libsolv RPM provide this file, I am surprised it is
not being loaded:
/usr/lib64/python3.6/site-packages/solv.py
And libsolv is hardly modified between versions:
https://github.com/theforeman/foreman-packaging/commits/rpm/develop/packages/pulpcore/libsolv

Also, it looks like neither katello 3.16 nor 3.17 rc1 support installation
on el8 yet:
https://theforeman.org/plugins/katello/3.17/installation/index.html

Also, we are supposed to install pulp-rpm (from the nightly repo, not 3.16)
in our molecule-based CI for pulp_installer. The CI installs pulp-file &
pulp-rpm for all pip install tests, but not RPM install tests. I'll start
on fixing this right now.
