We'll need to update the script to use python3-dnf vs. yum

[Javier Peña (jpena-c)]

This is strange, since the "yum" package provides the yum python library in CentOS 7. Is container-check running as part of a virtual environment?

[Kevin Carter (kevin-carter)]

++ to what Javier said, I suspect this issue is caused by a venv or pyenv which is not able to access the site packages. If the YUM module was actually missing from the system, yum itself would be broken. As such I'm inclined to close this as "not a bug."
