... the App Store must be connecting to your iMac at some point and for some period of time or your "2" wouldn't be there in the first place, so perhaps you ought to think around visiting the App Store and visit /Apps/System Prefs/App Store and allow El Cap to d/l and install the updates for you. Yeah, you may not necessarily want them, but coming directly from Apple they won't do you any harm, and if you're really hot to get rid of the "2", this may be your only way.
Not so much ...
Repeated attempts to access the App Store yielded equally repeated crap-outs; following is a small sample —
