After Ubuntu12.04 is installed, I use the Firefox browser to watch videos. Result the browser prompts that a suitable plug-in is missing and the player cannot be played. In the installation wizard, I selected the adobeflash plug-in.

However, after waiting for half an hour, the flash plug-in has not been downloaded yet, because there are other software to download, so I click to cancel the download of the flash plug-in. the result is stuck there after half an hour:

I closed the Ubuntu Software Center and used the following method to unlock it:

Copy codeThe code is as follows:
Sudo rm/var/cache/apt/archives/lock
