I'm having this issue on Inspiron 5559 and Windows 10 Pro (SO build 14393.693)
I don't have a solution but I can provide more information from the log files to help with troubleshooting.
For anyone interested, the log files are located in C:\ProgramData\Dell\Update\Logs\ and C:\ProgramData\Dell\SARemediation\log\.
General update process messages are in C:\ProgramData\Dell\Update\Logs\Service.log but post relevant messages are in C:\ProgramData\Dell\SARemediation\log\Deployer.log.
Here are lines from the Service.log after an update attempt:

I home this helps to get to the bottom of this issue. I'll be glad to assist if support o tech people need more info or log files.
