confluent ansible DOWNGRADE

Affected: 5.5.0 · 5.5.1 · 5.5.2 · 6.0.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.5.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.5.0 (Debian / Ubuntu)

apt-cache madison ansible sudo apt install ansible=<VERSION_BEFORE_5.5.0> sudo apt-mark hold ansible

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

dnf --showduplicates list ansible sudo dnf downgrade ansible-<VERSION_BEFORE_5.5.0> sudo dnf versionlock add ansible

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.
