internet2 grouper UPGRADE

Affected: >= 5.17.1 and < 5.20.5

Fixed in: 5.20.5

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.
