A fix has been implemented. Now that the correct hash has been validated, in order for this patch to install, users will need to redeploy the patch by performing one of the following:
1). Create new job with the patch included
2). Re-run of the previous job created
3). cloning the old job and execute
If the Patch is cached, reset will be required as the cached patch will have the same download URL when the error was first observed and continue to fail install.
Once the patch is redeployed, hash validation and patch install will be successful
