Looks like you originally installed from the breezy CD and used the
updater, which changed the CD designation from breezy to dapper

(1) If you don't have a 6.06 CD around, then just open the sources file

 gksudo "gedit /etc/apt/sources.list"

and either remove the CD ROM entry at the top of that file, or simply
comment it out by puting a # mark at the beginning of that line.

Then run 

sudo apt-get update

and you should be OK to install things, or in your case to finish your
upgrade with

sudo apt-get dist-upgrade

If that spits out errors, try running

sudo apt-get -f install 

You might need to repeat those last two if the system has become confused
by the interruption.

(2) Alternatively, if you have an up-to-date 6.06 LTS CD ( "final", June
1st copy, not beta or rc) , comment out or remove the line as described
above, then you can type

sudo apt-cdrom add

and the system will prompt you to insert the new CD, scan it and add it to
your sources.

If you have a decent Internet connection, I suggest the first strategy of
getting rid of your CD line in the sources.list file as above at (1) .

In either case it's important to do the "sudo apt-get update" step so as to
let the system know you have changed the list of available software. then
you can proceed with "sudo apt-get dist-upgrade"
