tanium deploy UPGRADE

Affected: >= 2.26.0 and < 2.26.1279 · >= 2.30.0 and < 2.30.175

Fixed in: 2.26.1279, 2.30.175

Safe to downgrade to: a release before 2.26.0

1. Check installed version

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

2. UPGRADE to 2.26.1279 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade deploy

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade deploy

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 2.26.0 (Debian / Ubuntu)

apt-cache madison deploy sudo apt install deploy=<VERSION_BEFORE_2.26.0> sudo apt-mark hold deploy

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

dnf --showduplicates list deploy sudo dnf downgrade deploy-<VERSION_BEFORE_2.26.0> sudo dnf versionlock add deploy

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.
