I'm using Lucid, and I have this in (System/Administration/Update Manager):
... that is, apparently I have turned off automatic updates.
However, occasionally, when I listen to music, I can hear it interrupt and I can see intense hard disk activity; usually when it stops, I get a new icon in the toolbar, with an exclamation mark:
If I right-click this icon, and click Preferences, I'm taken again to Update Manager, just on the first tab.
Thus, even if I have disabled automatic updates, automatic updates still run?
How do I get automatic updates to be disabled completely??
