I tried to reach this url but i got a 404 error, futher research in other web sites describes the same url. Also, i purge the browser and source list, reinstall from the oficial site and got the same error as before. Looks like an error from google's repository server.
From what I see using the Linux operating system, the problem is that the download package Google chrome was a mistake and was not installed correctly. I recommend you try to install the package download Google Chrome again.
