borland software interbase DOWNGRADE

Affected: 4.0 · 5.0 · 6.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.0

1. Check installed version

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

After downgrade

Restart the service, and keep the package held until a fixed release ships.
