recently ive tried to download several softwares from the software centre and as soon as i press install, it says that it failed to download package files and to check internet connection, this happened many time whist connected to several different networks, it also says that it requires the installation of untrusted package from an unuthenticated source.

What software center are you referring too? Can you post the website or software you are trying to download?

Connect to the Internet.Open a Terminal. Issue the following commands one-by-one:
sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get --fix-missing install
sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get clean
sudo apt-get autoremove
sudo apt-get update

Does it work now? Do you get any error messages?

Tip: You do not need to type commands into the Terminal. Highlight the command written on the web page. Move your cursor anywhere in the Terminal and press your mouse wheel or mouse middle button. Automatic Copy and paste! No spelling mistakes! No Typos! No other errors!

The 'untrusted packages' error is related to gpg signature signing, and could mean you haven't the keyring setup.

http://aplawrence.com/Basics/gpg.html

But this is a non-crucial issue if you are using the offical Ubuntu mirrors.

Try installing the same packages at the command line and paste the output here, and it will be easier to suss the problem:

Code:
sudo apt-get install nameofpackage
It could be an issue with the mirrors that you are using. Is the 'untrusted packages' new to you then?

My question would be Do you have enough HD space and are you using the Root or admin authorization? Do you have more than one User and are you using the right password? You may want to boot and when you see GRUB go to the second line and go to the restore area and see if you can get it to do the updates that may be required to fix possibly some broken packages.
