eng knowage UPGRADE

Affected: >= 6.1.0 and < 8.1.8

Fixed in: 8.1.8

Safe to downgrade to: a release before 6.1.0

1. Check installed version

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

2. UPGRADE to 8.1.8 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade knowage

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 6.1.0 (Debian / Ubuntu)

apt-cache madison knowage sudo apt install knowage=<VERSION_BEFORE_6.1.0> sudo apt-mark hold knowage

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

dnf --showduplicates list knowage sudo dnf downgrade knowage-<VERSION_BEFORE_6.1.0> sudo dnf versionlock add knowage

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.
