termix termix UPGRADE

Affected: >= 2.1.0 and < 2.3.2

Fixed in: 2.3.2

Safe to downgrade to: a release before 2.1.0

1. Check installed version

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

2. UPGRADE to 2.3.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade termix

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 2.1.0 (Debian / Ubuntu)

apt-cache madison termix sudo apt install termix=<VERSION_BEFORE_2.1.0> sudo apt-mark hold termix

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

dnf --showduplicates list termix sudo dnf downgrade termix-<VERSION_BEFORE_2.1.0> sudo dnf versionlock add termix

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.
