SCCM Fails to download updates

I was starting to post this as a question but I just got it working.  The updates for my SCCM install were failing to download. 

I found the log sample below from the patchdownloader.log

Log Sample Start:

After validating WSUS was working and the ability to download the updates outside of the wizard

Repointed my download location from internet on a new test package/update list to a pointless network location a couple of times, repointed to the internet and I got a partial download

I deleted and recreated one package and modified its package source share path. I am not sure how unique that path has to be per deployment package but I made the path definitely unique to this package. Once that Deployment Package was recreated my downloads appeared to work correctly. 

I also did not know that the initial download is processed through the system variable temp directoy on the site server
