[evgeni]

to test this:

• deploy 6.18
• podman login registry.redhat.io --authfile /etc/foreman/registry-auth.json …
• satellite-installer --enable-iop

test that it's really failing

[root@sat ~]# foreman-maintain update run
…

After the deploy of the fix it works:

dnf install -y rubygem-foreman_maintain-doc-1:1.14.2-1.20260318123913535263.pr1076.2.g639b298.el9.noarch rubygem-foreman_maintain-1:1.14.2-1.20260318123913535263.pr1076.2.g639b298.el9.noarch --disableplugin foreman-protector

satellite-maintain update run --whitelist="repositories-validate,check-non-redhat-repository"
