Unable to install macOS 11.x updates if initiated from a standard user account


We are piloting macOS 11 in our environment and are running into a multitude of issues. One of which is updating the OS. If the update is initiated from a standard user account(or if jamf policy kicks off the softwareupdate and the logged in user is NOT an admin) then the update fails to install.

/var/log/install.log reveals an issue copying the BaseSystem.dmg to the update volume because of a permission issue to Recovery:

  Anyone else seeing anything similar and or may know what I need to do to correct this? NONE of our users have local admin any longer.

We have it run in a policy for incremental weekly. Two parts One is the Software Update Policies and the other is a Execute command. 



Under file and processes> Execute Command "softwareupdate -i -a"

First, completely shut down your Mac via the Apple Toolbar. Then, hold down Command, Option, P, and R buttons on your keyboard as you restart your Mac. ... Resetting your PRAM will not only fix this particular OS X install issue, but it can also fix network issues, sound issues, and display issues.
