Comment 16 for bug 549217

Hi, I've done as you suggested above.

I did several fresh installs of Ubuntu on Virtualbox - however, slightly different behaviour was exhibited on different occasions. On the very first installation I performed, the Update Manager opened immediately after the installation had completed and suggested some Security Updates. I closed the Update Manager without installing the updates. I then followed the procedure you outlined above. After 10 minutes, nothing had happened. I left the virtual machine running over night, and came back the next day to find that (a) the Security Updates had apparently installed themselves (the power button was showing "Reboot required") and (b) upon manually starting Update Manager, no security updates were visible, but there were many non-security updates which I had not been notified about.
