Can't download anything from Software Center
Solution 1
codeblocks
and vlc
are in the Universe component (see the Repositories/Ubuntu community documentation wiki page). aircrack-ng
is not provided in Ubuntu 12.04's official software sources (though it is provided in the official software sources for previous Ubuntu releases, and will be provided again in Ubuntu 12.10).
I recommend fixing whatever problem is preventing codeblocks
and vlc
from being installed, before deciding which of the available methods you wish to use to install aircrack-ng
(since, depending on how you install that, the same problem might get in the way if not fixed).
So, to install codeblocks
and vlc
, first make sure this component is enabled by going to Edit > Software Sources... in the Software Center's top menu bar, and checking the box labeled Community-maintained free and open-source software (universe) (in the Ubuntu Software tab) if it isn't already checked. Then click Close.
That should fix the problem. Unless it was already checked. In that case, or if you know that you're also unable to install packages from the Main component (which is virtually always enabled, and you can see if it is in the same way), try the fix proposed in r000000000000t's answer.
Once this is fixed and you're able to install codeblocks
and vlc
, go ahead and install aircrack-ng
using one of the methods detailed in the answers here:

Not found There isn’t a software package called “codeblocks” in your current software sources. Not found There isn’t a software package called “vlc” in your current software sources
In terminal
Package 'aircrack-ng' has no installation candidate Package 'vlc' has no installation candidate
And I can't find any software in Synaptic either.
