jbook jbook DOWNGRADE

Affected: 1.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.4

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.4 (Debian / Ubuntu)

apt-cache madison jbook sudo apt install jbook=<VERSION_BEFORE_1.4> sudo apt-mark hold jbook

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

dnf --showduplicates list jbook sudo dnf downgrade jbook-<VERSION_BEFORE_1.4> sudo dnf versionlock add jbook

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.
