I can't install the AI2 Setup, I get a violation of quality message

[Xaro Castells]

Hello
I'm trying to install the emulator in AI2. My OS is Ubuntu 14.04. I followed the instructions at http://appinventor.mit.edu/explore/ai2/setup-emulator. However, when trying to perform step 1, which is install the AI2 setup software, by clicking on appinventor2-setup_2.3_all.deb, I get the following message:

"The installation of a package which violates the quality standards isn't allowed. This could cause serious problems on your computer. Please contact the person or organisation who provided this package file and include the details beneath.
