I'm running 12.04 LTS under VirtualBox for Mac, and I'm not getting an option for any upgrade to 12.04.2 in Update Manager. In Settings, "Notify me of a new Ubuntu version:" is set to "For long-term support versions". When I set it to "For any new version", I'm notified of 12.10. But cannot get it to offer 12.04.2 at all.
lsb_release -a in Terminal results in:
Distributor ID: Ubuntu Description: Ubuntu 12.04 LTS Release: 12.04 Codename: precise
The various terminal update options don't help either.
