ppgo jobs project ppgo jobs DOWNGRADE

Affected: 2.8.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.8.0

1. Check installed version

apt-cache policy ppgo-jobs || rpm -q ppgo-jobs || ppgo-jobs --version

2. No fixed release: DOWNGRADE to a release before 2.8.0 (Debian / Ubuntu)

apt-cache madison ppgo-jobs sudo apt install ppgo-jobs=<VERSION_BEFORE_2.8.0> sudo apt-mark hold ppgo-jobs

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list ppgo-jobs sudo dnf downgrade ppgo-jobs-<VERSION_BEFORE_2.8.0> sudo dnf versionlock add ppgo-jobs

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.
