According to that page there are several ways to accomplish the upgrade.
The simplest being to check your current update manager is new enough and
then to run it from the System/Administration menu so I did that.

The update manager correctly advises me that 6.06 is available and has a
button to do the upgrade.  All seemed to go well until it says:

Failed to fetch http://koti.mbnet.fi/~ots/ubuntu/breezy/Packages.gz 404 Not
Found
Failed to fetch http://koti.mbnet.fi/~ots/ubuntu/breezy/Sources.gz 404 Not
Found

in a dialog box and clicking OK then aborts the upgrade.
koti.mbnet.fibeing a Canonical domain and that I got the same errors
on 4 tries is making
me curious.  I guess I should try another method.
