Hey Sergio and Juan. Indeed, this fix was not included in 11.04 Beta 2. Rather, it was released after Beta 2. Please update your system to get the latest version of Software Center (currently 3.1.26.7 in the archives). You can simply use Update Manager to update, or if you prefer you can update Software Center alone using the terminal as follows:
sudo apt-get update sudo apt-get install software-center That should take care of this problem for you.
