I can't download anything from Ubuntu Software Center

I've installed ubuntu 13.04 a few day's ago and U.S.C. (Ubuntu Software Center) worked perfect. Yesterday I couldn't download any more, the proggress tab show the number 1 and it is Enabling component of the distribution with 1 item waiting: Updating cache

(I'm Dutch and 12 years old so I don't know much about computers)

When you install Ubuntu you have to do an update. You have to do this because in time of installing the system you have the OS as it was on release date. So updating improves your OS and protect your system with bug fixes etc.

Because we don't have much information about your current situation please open a terminal and type in

sudo apt-get update

and after that

sudo apt-get upgrade

Now you have the latest packages and can start working.

Its simple. Just run a few commands...

You can copy these commands and paste them into a Terminal (Ctrl+Alt+T):

sudo rm /var/lib/apt/lists/lock
sudo rm /var/cache/apt/archives/lock

The first command deletes one lock file and second deletes the other one in the cache directory.

Now run:

sudo apt-get update
sudo apt-get upgrade

Thats all.

This is because your system is busy installing updates. That's why you get an error using apt-get. Just let everything finish updating and it will work.
