kuka systemsoftware v\/kss UPGRADE

Affected: >= 8.2 and < 8.6.5

Fixed in: 8.6.5

Safe to downgrade to: a release before 8.2

1. Check installed version

apt-cache policy systemsoftware-vkss || rpm -q systemsoftware-vkss || systemsoftware-vkss --version

2. UPGRADE to 8.6.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade systemsoftware-vkss

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade systemsoftware-vkss

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 8.2 (Debian / Ubuntu)

apt-cache madison systemsoftware-vkss sudo apt install systemsoftware-vkss=<VERSION_BEFORE_8.2> sudo apt-mark hold systemsoftware-vkss

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

dnf --showduplicates list systemsoftware-vkss sudo dnf downgrade systemsoftware-vkss-<VERSION_BEFORE_8.2> sudo dnf versionlock add systemsoftware-vkss

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.
