puppet puppet enterprise UPGRADE

Affected: >= 2018.1.8 and < 2023.8.4 · 2025.3.0

Fixed in: 2023.8.4

Safe to downgrade to: a release before 2018.1.8

1. Check installed version

apt-cache policy puppet-enterprise || rpm -q puppet-enterprise || puppet-enterprise --version

2. UPGRADE to 2023.8.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade puppet-enterprise

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade puppet-enterprise

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 2018.1.8 (Debian / Ubuntu)

apt-cache madison puppet-enterprise sudo apt install puppet-enterprise=<VERSION_BEFORE_2018.1.8> sudo apt-mark hold puppet-enterprise

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

dnf --showduplicates list puppet-enterprise sudo dnf downgrade puppet-enterprise-<VERSION_BEFORE_2018.1.8> sudo dnf versionlock add puppet-enterprise

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.
