tickbh process lock DOWNGRADE

Affected: 0.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1.0

1. Check installed version

apt-cache policy process-lock || rpm -q process-lock || process-lock --version

2. No fixed release: DOWNGRADE to a release before 0.1.0 (Debian / Ubuntu)

apt-cache madison process-lock sudo apt install process-lock=<VERSION_BEFORE_0.1.0> sudo apt-mark hold process-lock

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

dnf --showduplicates list process-lock sudo dnf downgrade process-lock-<VERSION_BEFORE_0.1.0> sudo dnf versionlock add process-lock

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.
