Comment (by SergeyBiryukov):

 Replying to [comment:2 dd32]:
 > However, `WP_Automatic_Updater` doesn't expect a false return either and
 may fail further down the stack somewhere in the notify emails/etc. as
 they expect `true` or `WP_Error`.

 [attachment:25817.2.patch] makes sure `Core_Upgrader::upgrade()` returns
 `WP_Error` if `fs_connect()` failed.
