pivotal software application service UPGRADE

Affected: >= 665.0.0 and < 665.0.28 · >= 666.0.0 and < 666.0.21 · >= 667.0.0 and < 667.0.7

Fixed in: 665.0.28, 666.0.21, 667.0.7

Safe to downgrade to: a release before 665.0.0

1. Check installed version

apt-cache policy application-service || rpm -q application-service || application-service --version

2. UPGRADE to 665.0.28 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade application-service

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade application-service

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 665.0.0 (Debian / Ubuntu)

apt-cache madison application-service sudo apt install application-service=<VERSION_BEFORE_665.0.0> sudo apt-mark hold application-service

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

dnf --showduplicates list application-service sudo dnf downgrade application-service-<VERSION_BEFORE_665.0.0> sudo dnf versionlock add application-service

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.
