Fresh on the heels of my article outlining How to Install the Latest Firefox Web Browser, this article outlines how to install the Opera Web Browser on Ubuntu. I will outline how to configure the repository to subscribe to Opera Web Browser updates, install the required packages, and more.
Installing the Opera Web Browser using these steps requires that you subscribe to the official Opera Debian repository. This repository will ensure that you are kept up to date with the latest releases as well as security updates. To configure and activate the Opera repository, add the following line to your /etc/apt/sources.list file:
deb http://deb.opera.com/opera/ stable non-free
You’ll also want to import the GPG package signing key, to verify the downloaded packages. Importing the key can be done using the following command:
wget -O - http://deb.opera.com/archive.key | sudo apt-key add -
sudo aptitude update
Now that you have the Opera repository configured, you can install the latest Opera Web Browser package. Opera provides both 32bit and 64bit releases by way of their official repository. Install the correct architecture for your system using the following commands: (or click the linked package name)
sudo aptitude installopera
Once the package installation is finished you should have a new entry in your Applications menu. Opera Web Browser should be listed under Applications > Internet > Opera.
