powertech powerlock networksecurity DOWNGRADE

Affected: 4.7.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.7.1

1. Check installed version

apt-cache policy powerlock-networksecurity || rpm -q powerlock-networksecurity || powerlock-networksecurity --version

2. No fixed release: DOWNGRADE to a release before 4.7.1 (Debian / Ubuntu)

apt-cache madison powerlock-networksecurity sudo apt install powerlock-networksecurity=<VERSION_BEFORE_4.7.1> sudo apt-mark hold powerlock-networksecurity

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

dnf --showduplicates list powerlock-networksecurity sudo dnf downgrade powerlock-networksecurity-<VERSION_BEFORE_4.7.1> sudo dnf versionlock add powerlock-networksecurity

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.
