Thank you for pointing me in the right direction. Can't remember now if I upgraded from 10.04 via CD or Update Manager (maybe the first line of /etc/apt/sources.list suggests a CD install??). I append /etc/apt/sources.list - looks like CD sources are already commented out.<div>

Well, 100% of one of your CPU cores at a guess :-)<br>

No, I suspect it's stuck. Did you install from CD by any chance?<br>
<br>
There was a bug some time ago where apt was polling for the CD to check the<br>
package list.<br>
<br>
Check /etc/apt/sources.list for lines starting "deb cdrom:" and comment them<br>
out by placing a # character at the start of the line.<br>
