To install simply download the tarball, extract it to /usr/local/ and add /usr/local/go/bin to your $PATH. If you want to install it to a different location (I like to keep it in my home directory), you just to set $GOROOT to that path and set your $PATH accordingly. To update, just remove the old go dir and extract the new tarball in the same place. I'm ok with it.
Simply is never that simply. There is always something that happen to suck in IT. You think you have done everything right and sometime, you just made a little misinterpretation that screw everything and you can lose a lot of time figuring out what.
That being said, I had no problem installing go on my ubuntu, despite the fact that I consider that the installation process sucks.
That's it, it is that simple. All you have to do now is set your $GOPATH, and you would need to do that even if you had installed Go through a package.
