Trying to Supervise an iPad and it fails with the above error message pulled from the system logs.
Name - No change
Supervision - ON
Restore: Don't restore
Profiles: none checked
After installing the "latest" iOS, the iPad starts up with new setup screens. Meanwhile, Apple Configurator says it failed.
Order of messages after iOS install.
"Checking activation state."
"Activation failed. Use iTunes."
I've tried setting the iPad up like normal with no passcode and letting iTunes back it up. Then I run the exact same setup and of course it wipes the iPad and starts the setup screens after it's done like it hasn't been activated.
