Linux Software Repositories

First, use rpm to install the key, as described in the RPM setup guide.

To add the Google repository, run the following command as root:

zypper sa -t YUM http://dl.google.com/linux/rpm/stable/i386 google  

If you are running a 64-bit distribution, you should also add the x86_64 repository, which will provide you with native 64-bit versions of some of our software:

zypper sa -t YUM http://dl.google.com/linux/rpm/stable/x86_64 google64  
then use zypper as usual, e.g.
zypper in picasa
