gongrzhe terminal-controller-mcp DOWNGRADE

Affected: 0.1.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1.7

1. Check installed version

apt-cache policy terminal-controller-mcp || rpm -q terminal-controller-mcp || terminal-controller-mcp --version

2. No fixed release: DOWNGRADE to a release before 0.1.7 (Debian / Ubuntu)

apt-cache madison terminal-controller-mcp sudo apt install terminal-controller-mcp=<VERSION_BEFORE_0.1.7> sudo apt-mark hold terminal-controller-mcp

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

dnf --showduplicates list terminal-controller-mcp sudo dnf downgrade terminal-controller-mcp-<VERSION_BEFORE_0.1.7> sudo dnf versionlock add terminal-controller-mcp

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.

Exact fixes by distribution

A distro patch exists: prefer upgrading over downgrading.
