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

2. No fixed release: DOWNGRADE to a release before 1.0.0 (Debian / Ubuntu)

apt-cache madison thesystem sudo apt install thesystem=<VERSION_BEFORE_1.0.0> sudo apt-mark hold thesystem

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

dnf --showduplicates list thesystem sudo dnf downgrade thesystem-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add thesystem

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.
