Issue/Introduction

When upgrading, the following error can be seen:

[...]

After freeing some space, the upgrade is still failing with the following error:

X/X/X X:X X (ReleaseUtilityTask) Could not verify package for release = 16.1.0

Environment

Release : 16.1.1

Cause

The disk still does not have enough capacity to unpack all the necessary files for the installation/upgrade.

Resolution

Free up additional disk space, delete the installation files and extract them again from the ISOs (so that no corrupted files remain), and try to run the installer again.
