seatd project seatd UPGRADE

Affected: >= 0.6.0 and < 0.6.4

Fixed in: 0.6.4

Safe to downgrade to: a release before 0.6.0

1. Check installed version

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

2. UPGRADE to 0.6.4 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade seatd

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 0.6.0 (Debian / Ubuntu)

apt-cache madison seatd sudo apt install seatd=<VERSION_BEFORE_0.6.0> sudo apt-mark hold seatd

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

dnf --showduplicates list seatd sudo dnf downgrade seatd-<VERSION_BEFORE_0.6.0> sudo dnf versionlock add seatd

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.
