Allow user to install from unknown sources on Android 5.0 I have Nexus 10 and have 2 users on it.
On Android 4.4 both Users could install application from unknown sources.

After upgrade to Android 5.0 admin user has Security-Unknown Sources  flag is "on" but secondary User has this flag greyed and disabled.

How can I switch it on?
It might be possible to do it with a rooted device, but on Android 5.0 only the primary user can install apps from Unknown Sources.
