1. Check installed version

apt-cache policy privatewire-gateway || rpm -q privatewire-gateway || privatewire-gateway --version

2. No fixed release: DOWNGRADE to a release before 3.7 (Debian / Ubuntu)

apt-cache madison privatewire-gateway sudo apt install privatewire-gateway=<VERSION_BEFORE_3.7> sudo apt-mark hold privatewire-gateway

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

dnf --showduplicates list privatewire-gateway sudo dnf downgrade privatewire-gateway-<VERSION_BEFORE_3.7> sudo dnf versionlock add privatewire-gateway

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.
