Opera

Opera is a powerful, cross-platform freeware1) web browser.

Installation

Ubuntu

10.04 Lucid and above

Simply download the .deb package for Ubuntu and install it as usual (e.g. via double click or by using dpkg -i). If an entry is not already existing, the installer automatically adds the official Opera repository to your package sources,2) including the key to authenticate it. So you don't have to care about updates manually.

Second way: using the Opera repository

Simply add the repository Opera provides:

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

You need the following key to authenticate the new repository:

sudo apt-key adv --recv-keys --keyserver keyserver.ubuntu.com 9D1A0061

Update your sources:

sudo apt-get update

Now you can install the following package(s):

Windows

XP and above

Simply download the installer and execute it with administrator privileges.

Or use Opera Portable if you want to run Opera without installation.

Tips and tricks

Use Opera as default browser (Ubuntu, GNOME)

Open “System→Preferences→Preferred Appliactions”, “Internet” tab. Use the selection box to choose Opera as browser. If Opera is not listed, choose “Custom” and use opera %s as command.

Add additional dictionaries

By default, Opera comes with an American English dictionary. But you only need a few clicks to add more languages:

  • Type something into an input field or textarea on a arbitrary website.
  • Mark the string you typed and right click on it.
  • Choose “Dictionaries→Add/Remove Dictionaries…” from the context menu and select the additional dictionaries you would like to use. You can choose the default dictionary afterwards.

Troubleshooting

Opera does not start (Ubuntu)

If Opera does not start, try to install the following package:

This should solve the problem.

Special characters don't work (Ubuntu 64bit)

Try to create a symlink to the 32bit locale file:

sudo ln -s -T /usr/lib64/locale /usr/lib32/locale
