Safe to downgrade to: a release before 17.0.0

1. Check installed version

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

2. UPGRADE to 26.1.6 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ironic

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 17.0.0 (Debian / Ubuntu)

apt-cache madison ironic sudo apt install ironic=<VERSION_BEFORE_17.0.0> sudo apt-mark hold ironic

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

dnf --showduplicates list ironic sudo dnf downgrade ironic-<VERSION_BEFORE_17.0.0> sudo dnf versionlock add ironic

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.
