redhat satellite UPGRADE

Affected: >= 6.0 and <= 6.19

Fixed in: newer than 6.19

Safe to downgrade to: a release before 6.0

1. Check installed version

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

2. UPGRADE to newer than 6.19 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade satellite

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade satellite

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.0 (Debian / Ubuntu)

apt-cache madison satellite sudo apt install satellite=<VERSION_BEFORE_6.0> sudo apt-mark hold satellite

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list satellite sudo dnf downgrade satellite-<VERSION_BEFORE_6.0> 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.
