borland software interbase DOWNGRADE

Affected: 2007

Fixed in: no fixed release known

Safe to downgrade to: a release before 2007

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2007 (Debian / Ubuntu)

apt-cache madison interbase sudo apt install interbase=<VERSION_BEFORE_2007> sudo apt-mark hold interbase

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

dnf --showduplicates list interbase sudo dnf downgrade interbase-<VERSION_BEFORE_2007> sudo dnf versionlock add interbase

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.
