apache ignite UPGRADE

Affected: >= 2.0.0 and < 2.18.0

Fixed in: 2.18.0

Safe to downgrade to: a release before 2.0.0

Note

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

apt-cache madison ignite sudo apt install ignite=<VERSION_BEFORE_2.0.0> sudo apt-mark hold ignite

dnf --showduplicates list ignite sudo dnf downgrade ignite-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add ignite

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.
