With the latest LTS version of Ubuntu Linux available; 14.04 the Trusty Tahr we look at installing the popular Chrome browser into the os from the Google repositories. Firstly, we can browse what Google has to offer by visiting http://www.google.com/linuxrepositories. From here we can see not only the repo contents but obtain the public signing key. To download this and add it to apt:
wget -q -O - https://dl-ssl.google.com/linux/linux_signing_key.pub | sudo apt-key add -
Then we can edit the apt repositories list to add in the Google repo.
sudo sh -c 'echo "deb http://dl.google.com/linux/chrome/deb/ stable main" >> /etc/apt/sources.list.d/google.list'
Here we create a new file in the sources.list.d directory but equally you could edit the sources.list file.
