Remove downloaded upgrade files *before* install

[holiday]

In 10.04, I mistakenly clicked Upgrade. The upgrade downloaded the upgrade info and then went on to the upgrade dialog telling me that it would download and install the upgrade. I cancelled the dialog, but the package manager will be expecting a go command at some point.

I really really do not want to upgrade, in fact on my other computers I've switched to CrunchBang.

What can I do to remove the downloaded files, and reset the package manager so that it is not expecting to install the upgrade.

Thanks

Removing the downloaded files is easy:

sudo apt-get clean

As to the rest of your post, I don't quite understand it. What package manager are you using? aptitude? synaptic? I guess in synaptic it's a matter of filtering on packages marked for upgrade and unmarking them. IIRC, pressing Ctrl+n will also do it. In aptitude, Ctrl+u will undo the last action. You also can

sudo aptitude keep-all

Or you started an upgrade to a newer Ubuntu release in update-manager? Where have you canceled it? On the following screen?
