I'm running Ubuntu 10.10.
A couple weeks ago I tried to install debsig-verify and I may have done it incorrectly (keys wrong?).
The next time the update-manager ran, it complained I could only do a partial upgrade (almost nothing) because of the presence of debsig-verify. So I uninstalled debsig-verify and got my upgrade.
Now, today, Apr 27, update-manager again says it can only do a partial upgrade. However, when I click OK, it wants to upgrade 322 packages, most of which are KDE (I use Gnome mostly).
1) Is my mis-install of debsig-verify related to the massive KDE upgrade?
2) I mostly use Gnome (though I like KDE better). If something goes wrong, will it kill anything inside Gnome?
3) It says it wants up upgrade Nautilus?!? I thought that was part of Gnome?!? So now I'm really confused.
4) Is this KDE upgrade a normal upgrade or did I break something?

I thought I'd ask before killing something...
