rockwellautomation thinmanager UPGRADE

Affected: >= 11.1.0 and < 11.1.8 · >= 11.2.0 and < 11.2.9 · >= 12.0.0 and < 12.0.7 · >= 12.1.0 and < 12.1.8 · >= 13.0.0 and < 13.0.5 · >= 13.1.0 and < 13.1.3 · >= 13.2.0 and < 13.2.2

Fixed in: 11.1.8, 11.2.9, 12.0.7, 12.1.8, 13.0.5, 13.1.3, 13.2.2

Safe to downgrade to: a release before 11.1.0

1. Check installed version

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

2. UPGRADE to 11.1.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade thinmanager

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 11.1.0 (Debian / Ubuntu)

apt-cache madison thinmanager sudo apt install thinmanager=<VERSION_BEFORE_11.1.0> sudo apt-mark hold thinmanager

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

dnf --showduplicates list thinmanager sudo dnf downgrade thinmanager-<VERSION_BEFORE_11.1.0> sudo dnf versionlock add thinmanager

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.
