Fixed in: no fixed release known

apt-cache policy listhandler || rpm -q listhandler || listhandler --version

2. No fixed release: DOWNGRADE to a release before 6.x-1.0 (Debian / Ubuntu)

apt-cache madison listhandler sudo apt install listhandler=<VERSION_BEFORE_6.x-1.0> sudo apt-mark hold listhandler

After downgrade

Restart the service, and keep the package held until a fixed release ships.
