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.

it don't work, it says: E: Could not get lock /var/lib/apt/lists/lock - open (11: Resource temporarily unavailable) E: Unable to lock directory /var/lib/apt/lists/ E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable) E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it? – kaj Aug 25 '13 at 17:13
Did you do that after a reboot? And with superuser rights? – Nick Lehmann Aug 25 '13 at 18:56
superures rights? is that something like administrator, yes – kaj Aug 26 '13 at 9:12
Yes, you're absolutley right. For that use sudo. Maybe there is another progress running that blocks the update or update the OS itself. – Nick Lehmann Aug 29 '13 at 13:04

Its simple....

Just run a few commands...

firt run this command. you can copt it and paste to terminal.

Open Terminal clrl+alt+T

Enter command:

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

1st command is to delete lock file and 2nd is to delete lock file in 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.
