It could also be that you aborted a previous install in the middle, so try to run:
sudo apt-get install -f
The "install -f" tells apt-get to fix, or resume, interrupted installations.
Then try this:
sudo apt-get update
sudo apt-get upgrade
The 'update' command synchronizes apt-get with the repositories, and the 'upgrade' command will upgrade all your system to the latest version of the packages (if that's not what you want, don't run the 'upgrade' command, but do run the 'update').
You can also try to clean the apt cache:
sudo apt-get clean
You are also seeing errors that are related to clam antivirus. Can you give us more info on how that fits in here?
I did run the commands you recommended. apt-get update, apt-get autoremove, apt-get upgrade. Then the syst asked to set the Xubuntu 8.10 Intrepid Ibex...Although my distro is Hardy Heron...
To post a fuller report on this machine's "fits", i will let it be for a while. In a couple of days i'll post again.
Thank you very much..!!
