confluent cp-ansible DOWNGRADE

Affected: 5.5.0 · 5.5.1 · 5.5.2 · 6.0.0

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