Please open a Terminal ("Applications" "Accessoires" "Terminal") and paste the output of typing

sudo apt-get update

and then

sudo apt-get upgrade

To correct this problem just open Terminal (Applications → Accessories → Terminal) and type:

sudo dpkg --configure -a

Give your user password when requested. You will not see anything, but type it and press enter.

Then retry to update and/or to install desired package.

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

sudo dpkg --clear-avail
sudo dpkg --configure -a

then to update and upgrade and also check pending or missing packages, still using terminal type:

sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove

Hope this helps
