redhat satellite DOWNGRADE

Affected: 6.13 · 6.14 · 6.15

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.13

1. Check installed version

apt-cache policy satellite || rpm -q satellite || satellite --version

2. No fixed release: DOWNGRADE to a release before 6.13 (Debian / Ubuntu)

apt-cache madison satellite sudo apt install satellite=<VERSION_BEFORE_6.13> sudo apt-mark hold satellite

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list satellite sudo dnf downgrade satellite-<VERSION_BEFORE_6.13> sudo dnf versionlock add satellite

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
