I went to download Google Earth and it started out fine until I got some warnings about it not be from verified sources etc. I stopped there and figured I'd ask here if there is any reason I shouldn't install it. Is this just boilerplate warnings from Canonical because it isn't one of their products? Or could GE harm my computer? Also, it's a .deb file. Do I "save" it or "open" it when I download? Does it install easily, or do I have to have superUbuntu powers to make it work? Thanks in advance for any help.
