With our devices I can update anything up to 14.6, but once any device it seems reaches 14.6 and then tries the update command for 14.7 or 14.71 they fail with the below. Any ideas?
Devices are iPad 7th and 8th gen, plus 5th gen iPad Minis.
The operation couldn’t be completed. (com.apple.softwareupdateservices.errors error 83.)
I have this happen as well. It takes forever to get a fleet of 700+ iPads updated. I'm lucky to get 50% to update in a first pass. I'm not sure but for me it seems like having a VPN on attributes to this. It seems to do better (but not always) when off.
The Defer Software Update restriction is ultimately the cause of my issue. The only way I have reliably found to push updates was to move the Defer Software Update restriction into its own profile by itself, then scope it as you normally would. When you want to send an update, you would then add your device to the exclusion list or remove it from scope.
I have seen a multitude of issues/instances where specific versions only seem to play well with one another in the update scenario even when they are all within the 90 day window of one another.
example: a Device on 15.0 can receive 15.1, or 15.2 but not 15.1.1
