Cause

These errors generally indicate that the software image being used for the upgrade is incomplete or was corrupted during the transfer.

Resolution

Confirm the MD5 has of the downloaded software image.

Ensure the VM that is hosting the VCG has sufficient memory for the new software image.

This should allow the upgrade to complete as expected.
