teamwire teamwire UPGRADE

Affected: >= 2.0.1 and < 2.3.0

Fixed in: 2.3.0

Safe to downgrade to: a release before 2.0.1

1. Check installed version

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

2. UPGRADE to 2.3.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade teamwire

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 2.0.1 (Debian / Ubuntu)

apt-cache madison teamwire sudo apt install teamwire=<VERSION_BEFORE_2.0.1> sudo apt-mark hold teamwire

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

dnf --showduplicates list teamwire sudo dnf downgrade teamwire-<VERSION_BEFORE_2.0.1> sudo dnf versionlock add teamwire

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.
