open-mss mission support system UPGRADE

Affected: >= 5.0.0 and < 8.3.3

Fixed in: 8.3.3

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy mission-support-system || rpm -q mission-support-system || mission-support-system --version

2. UPGRADE to 8.3.3 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mission-support-system

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mission-support-system

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 5.0.0 (Debian / Ubuntu)

apt-cache madison mission-support-system sudo apt install mission-support-system=<VERSION_BEFORE_5.0.0> sudo apt-mark hold mission-support-system

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

dnf --showduplicates list mission-support-system sudo dnf downgrade mission-support-system-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add mission-support-system

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.
