I followed this question : How to install Chrome browser properly via command line?

However, It is not the same as the one mentioned in google's website : http://www.google.com/linuxrepositories/ I want to do this one instead.

The process is:

On an APT-based system (Debian, Ubuntu, etc.), download the key and then use apt to install it.

wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -

sudo apt-get update

what would be the next step ?

I tried sudo apt-get intsall google-chrome and I ended up with this error
