bosch video management system UPGRADE

Affected: >= 7.5 and <= 11.1.1

Fixed in: newer than 11.1.1

Safe to downgrade to: a release before 7.5

1. Check installed version

apt-cache policy video-management-system || rpm -q video-management-system || video-management-system --version

2. UPGRADE to newer than 11.1.1 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade video-management-system

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade video-management-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 7.5 (Debian / Ubuntu)

apt-cache madison video-management-system sudo apt install video-management-system=<VERSION_BEFORE_7.5> sudo apt-mark hold video-management-system

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

dnf --showduplicates list video-management-system sudo dnf downgrade video-management-system-<VERSION_BEFORE_7.5> sudo dnf versionlock add video-management-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.
