Fixed In Version: selinux-policy-34.1.44-1.el9
Doc Type: Bug Fix
Doc Text:
Cause: SELinux denies subscription-manager package to execute gpg and gets blocked. Consequence: When a repository configuration changes to "repo_gpgcheck=1", the rhsmcertd worker executes gpg or gpgsm to perform a GPG signature check on this repository's metadata. Fix: Allow rhsmcertd execute gpg Result: No SELinux denials
