baryhuang aws resources mcp server DOWNGRADE

Affected: 0.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1.0

1. Check installed version

apt-cache policy aws-resources-mcp-server || rpm -q aws-resources-mcp-server || aws-resources-mcp-server --version

2. No fixed release: DOWNGRADE to a release before 0.1.0 (Debian / Ubuntu)

apt-cache madison aws-resources-mcp-server sudo apt install aws-resources-mcp-server=<VERSION_BEFORE_0.1.0> sudo apt-mark hold aws-resources-mcp-server

dnf --showduplicates list aws-resources-mcp-server sudo dnf downgrade aws-resources-mcp-server-<VERSION_BEFORE_0.1.0> sudo dnf versionlock add aws-resources-mcp-server

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.
