Resolution

1.a Unset system release version, if set: subscription-manager release --unset
or
1.b Remove file /etc/dnf/vars/releasever if hardcoded dnf release server version: rm /etc/dnf/vars/releasever
2. Clean DNF cache: dnf clean all
3. Rerun upgrade check: satellite-maintain upgrade check
4. Run upgrade: satellite-maintain upgrade run

Root Cause

The system had a fixed release version set, causing conflicts during package updates.

Diagnostic Steps

  • Verify system release version: subscription-manager release
Yum/dnf history:
Updating Subscription Management repositories.
This system has release set to 9.6 and it receives updates only for this release.
  • Verify if Hardcoded DNF Release Version is present in the system
cat /etc/dnf/vars/releasever
9.6
