Broken packages - can't upgrade from 9.10 to 10.04

Update: 07:30 PST 6/17/2011:
Manfred,
Thanks for your reply.
1) I had already removed the CD-Rom entries.
2) The command for getting the key worked nicely <Grin>
3) I succeeded in upgrading (fumbled my way through) by using the "Smart" upgrade option - probably due to 3rd party software
4) Terminal output is as follows:

dmg@krikit:~$ uname -a
Linux krikit 2.6.32-32-generic #62-Ubuntu SMP Wed Apr 20 21:54:21 UTC 2011 i686 GNU/Linux
dmg@krikit:~$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 10.04.2 LTS
Release: 10.04
Codename: lucid

Looks goor to me <g> Many Thanks
Dave G.

Update: 21:00 6/16/2011 -Although the "fix broken packages" didn't work (hence the input below) executing the suggested trouble shooting sequence seems to have fixed the problem,
I successfully upgraded the Basic Ubuntu OS from 9.10 to 10.04 LTS using the Upgrade System in Package Manager..
I have not yet tried updating the non-canonical S/W or an online update.
More later...good or bad :)

Trying to upgrade a 9.10 installation to 10.04
No go !!
terminal output of command sequence per trouble shooting page follows:
