websense triton DOWNGRADE

Affected: 7.8.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 7.8.3

1. Check installed version

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

After downgrade

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

Affected: <= 7.7

Fixed in: newer than 7.7
