Quick Update
I was checking out the log files again and decided to hit the retry update button so see what the log file did. I noticed that it moved on to another file. Because of this I decided to hit the retry button 10 times, and again it was moving on to new files.
This made me think, “Is it moving the files but not deleting?” So I hit retry another 100 times 
and checked my Nextcloud directory and saw that its populating the updated files in place.
After that I sat and hit the retry button OVER 9000! more times and the updater finally passed and completed. Now my server is updated and all that is left to do is to delete the “Updater” files that is located where my data is saved, which is on my NAS mount point.
The problem resides with the updater not being able to delete files out of the mounted NFS NAS folder. The NFS share is set public on the remote NAS permissions and the fstab permissions are set to default. Is there documentation on how you set your permission for an NFS share used as your data drive?
