inductiveautomation ignition UPGRADE

Affected: >= 8.1.0 and < 8.1.35

Fixed in: 8.1.35

Safe to downgrade to: a release before 8.1.0

1. Check installed version

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

2. UPGRADE to 8.1.35 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ignition

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 8.1.0 (Debian / Ubuntu)

apt-cache madison ignition sudo apt install ignition=<VERSION_BEFORE_8.1.0> sudo apt-mark hold ignition

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

dnf --showduplicates list ignition sudo dnf downgrade ignition-<VERSION_BEFORE_8.1.0> sudo dnf versionlock add ignition

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.
