Ubuntu usually at startup and on regular basis try to download security updates...
So please keep your Ubuntu switched on for more than 30 minutes with no package manager opened such as Synaptic, and then try to update... from terminal.

Then to get Ubuntu fully upgraded, 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 apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade

Report errors here.

Hope this helps
