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

3. If no update is available yet, DOWNGRADE to a release before 4.6.0 (Debian / Ubuntu)

apt-cache madison powerflex-manager sudo apt install powerflex-manager=<VERSION_BEFORE_4.6.0> sudo apt-mark hold powerflex-manager

dnf --showduplicates list powerflex-manager sudo dnf downgrade powerflex-manager-<VERSION_BEFORE_4.6.0> sudo dnf versionlock add powerflex-manager

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.
