I uninstalled kpackagekit using Ubuntu software center. When it uninstalled, it also uninstalled some dependencies. I was not aware it would do that. Now, if I try to install any software using Ubuntu software center, I get the error

"This error could be caused by required additional software packages which are missing or not installable. Futhermore there could be a conflict between software packages which are not allowed to be installed at the same time."

How can I resolve this? For example, when I try to install shutter, I get the error

"Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:

The following packages have unmet dependencies:

shutter: Depends: libxml-simple-perl but it is not installable  
         Depends: libgoo-canvas-perl but it is not going to be installed"

Migrating to AskUbuntu at the request of the asker. – DMA57361 Feb 9 '11 at 19:22
why would you uninstall kpackagekit in the first place?, and by the looks of it if you cant reinstall it, you broke your system, seems like you can't update anything now – Uri Herrera Feb 9 '11 at 19:56
@arul -- what version of Ubuntu are you using? (e.g., 10.04 or 10.10, 32-bit, 64-bit....) And I'm assuming you're running the Gnome version (just Ubuntu) as opposed to Kubuntu (KDE) or another? – belacqua Feb 9 '11 at 22:29

You might want to reinstall kpackagekit by opening up a terminal. It should be under "Applications" -> "System Tools" or "Accessories" -> "Terminal".

Now type in the following commands, pressing Enter after a new line:

sudo apt-get update
sudo apt-get install kpackagekit

This should reinstall kpackagekit along with its dependencies.
