derbynet derbynet DOWNGRADE

Affected: 9.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 9.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 9.0 (Debian / Ubuntu)

apt-cache madison derbynet sudo apt install derbynet=<VERSION_BEFORE_9.0> sudo apt-mark hold derbynet

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

dnf --showduplicates list derbynet sudo dnf downgrade derbynet-<VERSION_BEFORE_9.0> sudo dnf versionlock add derbynet

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.
