You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest

Expected outcome:
foreman-release successfully upgraded

Foreman and Proxy versions:
any. In this example 1.17.1
Foreman and Proxy plugin versions:

[e.g. logs from Foreman and/or the Proxy, modified templates, commands issued, etc]

I wonder why you have foreman-plugin installed. Typically it’s a build dependency for plugins.

If you try to remove foreman-plugin, what would happen? It could be a valid workaround.
