The bottom line is that if there are several packages from the Extra packages on the device (dhcp, security, system, wirelles), then The Dude can not update the RouterBOARD and produces an error: “some packages unavailable”. If your device does not have a package wirelles, the update passes without problems.
When you have some router which has both the “bundle” package and a separate package “wireless” you first have to resolve that problem manually.
(it is an error that could sometimes occur in older versions)
