1. Check installed version

apt-cache policy bsb2ppm || rpm -q bsb2ppm || bsb2ppm --version

2. No fixed release: DOWNGRADE to a release before 0.0.6 (Debian / Ubuntu)

apt-cache madison bsb2ppm sudo apt install bsb2ppm=<VERSION_BEFORE_0.0.6> sudo apt-mark hold bsb2ppm

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

dnf --showduplicates list bsb2ppm sudo dnf downgrade bsb2ppm-<VERSION_BEFORE_0.0.6> sudo dnf versionlock add bsb2ppm
