Error Message:

The error message is shown as the encryption keys are not available to decrypt the upgrade package:

Resolution

Some Unity OE upgrades cannot be done directly and require intermediate upgrade steps.

The below table describes the valid upgrade paths. Unity systems running versions earlier than 5.1 must upgrade to 5.4.1 before upgrading to version 5.5. This is due to changes in support for TLS, KMIP, and encryption keys between pre-5.1 versions and 5.5. 

Supported Upgrade Paths:

From 4.x 4.x → 5.4.1.x 4.x → 5.4.1.x → 5.5.0.x 4.x → 5.4.1.x → 5.5.1.x
