apt-cache madison services sudo apt install services=<VERSION_BEFORE_7.x-3.0> sudo apt-mark hold services

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

dnf --showduplicates list services sudo dnf downgrade services-<VERSION_BEFORE_7.x-3.0> sudo dnf versionlock add services

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.
