Before I had installed Chromium 20 from wolf\crack PPA, but later I had uninstalled it when I know it is not an official PPA.
I found it at the Ubuntu package repository for download, I think its official version, but when I install it with the software center it still downloads the version 20, should I trust it?
I had tried to install Chromium from the chromium-browser_20.0.1132.47~r144678-0ubuntu0.12.04.1_i386.deb which I had downloaded in my computer, but the Ubuntu Software Center download it again and by checking the 2 downloaded files md5, I found them is not the same, is it fine?
