There is a problem with Ubuntu 13.04 that disallows Google's Chrome web browser from being installed without making a fuss. In short, the problem is that google needs libudev0 (>= version 147), but that package is not available in the repositories.
libudev0 may not be in the Ubuntu repositories, but it IS in the parent-distribution (Debian)'s repositories. We can go there and download libudev0, and then install the program.
1) Go to http://ftp.us.debian.org/debian/pool/main/u/udev/libudev0_175-7.1_amd64.deb and download the .deb
2) Install the file like you normally would (double click it in Files or use dpkg -i).
3) Download the Google Chrome package from https://www.google.com/intl/en/chrome/browser/thankyou.html?brand=CHMB
4) Install the Chrome .deb file however you comfortably do so.
If you messed up beforehand, you will want to run "sudo apt-get install -f" from the Terminal to clean any broken packages that apt tried to get.
