apache doris mcp server UPGRADE

Affected: >= 0.1.0 and < 0.6.1

Fixed in: 0.6.1

Safe to downgrade to: a release before 0.1.0

1. Check installed version

apt-cache policy doris-mcp-server || rpm -q doris-mcp-server || doris-mcp-server --version

2. UPGRADE to 0.6.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade doris-mcp-server

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade doris-mcp-server

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 0.1.0 (Debian / Ubuntu)

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

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

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