Opera is one of the bests web browsers, and you can download it for your Linux Distro from its <a href=”http://www.opera.com/download/?platform=linux” target=”blank’>website</a>

But if you would like to be able to upgrade your opera using apt with your Debian or Ubuntu you better use repositories. Debian

You have to edit your /etc/apt/sources.list, and add this line.

For Etch

deb http://deb.opera.com/opera etch non-free

For Sid

deb http://deb.opera.com/opera sid non-free

For Lenny

deb http://deb.opera.com/opera lenny non-free

Now you need to import the gpg-key.

gpg –keyserver subkeys.pgp.net –recv-key 6A423791 gpg –fingerprint 6A423791 gpg –armor –export 6A423791| apt-key add -

and the update de database

apt-get update

Ubuntu

Just like with Debian you first need to edit the file

/etc/apt/sources.list

And add one of these two lines depending on which source you prefer, canonical or opera.

for canonical source

deb http://archive.canonical.com/ubuntu feisty-commercial main or deb http://archive.canonical.com/ubuntu edgy-commercial main or deb http://archive.canonical.com/ubuntu dapper-commercial main

depending if you are using Dapper, Edgy or Feisty

for opera source

deb http://deb.opera.com/opera/ stable non-free

Install the gpg-key

sudo gpg –keyserver subkeys.pgp.net –recv-key 6A423791 sudo gpg –fingerprint 6A423791 sudo gpg –armor –export 6A423791| sudo apt-key add -

update the database

sudo apt-get update

Debian or Ubuntu

Now you have your source installed and your database updated you can install opera.

sudo apt-get install opera
