compaq acms DOWNGRADE

Affected: 4.3 · 4.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.3

dnf --showduplicates list acms sudo dnf downgrade acms-<VERSION_BEFORE_4.3> sudo dnf versionlock add acms

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.
