Software center has disappeared

Question

I'm an absolute newby for Linux / Ubuntu. Yesterday I installed Ubuntu 11.10 on an old computer. It seemed to work fine. However today when I started the computer again the software center had disappeared!!

It wasn't in my starter list. When I used the Dash button it wasn't in my application list.

In the Dash center you can also look to applications ready to download and there it was, the software center. But how do I download the software center without software center?

Double clicking, right clicking, nothing seems to work.

How can I get back the software center, and how do I prevent it from disappearing in the future?

Answer 1

Just run the following command in a terminal:

sudo apt-get install software-center

The above command will install software-center in your computer. If it ever gets uninstalled or "disappears", you can run the command again to install it.

Answer 2

First, search for Ubuntu Software in the Dash.

If you found it, just drag it to the dock (or starter list ;) )

If Software Center doesn't appears, then open the Terminal program, searching in the Dash, and type sudo apt-get install software-center. Press Enter. Type your password (it won't appear anything while you type!), press Enter, press Y when asked and Enter again. When the installer finishes, search again in the Dash, and drop the icon to the Dock.
