Comment 64 for bug 356152

Same here with Lucid-amd64 and NBR.

Just a guess from me:
I have configured a "true" root-account and the 1st user is not listed in /etc/sudoers (this is default when installing from alternate CD).

Probably update-manager does not get launched, because user does not have proper permissions? Should be launched by 'gksu ...' instead of 'gksodo ..' to ask for root password?

Netbook-Rewmix does probably not launch because it is used most of the time on batteries?

In bouth cases the old beheaviour with a notification icon popping up in the panel would solve the issue.
