neoengine neoengine DOWNGRADE

Affected: 0.8.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.8.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.8.2 (Debian / Ubuntu)

apt-cache madison neoengine sudo apt install neoengine=<VERSION_BEFORE_0.8.2> sudo apt-mark hold neoengine

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list neoengine sudo dnf downgrade neoengine-<VERSION_BEFORE_0.8.2> sudo dnf versionlock add neoengine

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.
