To install Opera on Debian the Opera repository needs to be added and then the Opera package installed.
In the actions taken below the command line will be used. For maintaining the packages on my main computer I mostly use the command line, although sometimes it can be nice to see all of the packages laid out, together with search and filtering, in the Synaptics package manager.
Open a terminal program, such as Konsole. (Start>Applications>System>Konsole in KDE4). change to root user using su root and entering the associated password.
Adding Opera Repository
There are two repositories for Opera: stable and beta versions. Both are listed below, the stable one is shown as active, with the beta one commented-out.
deb http://deb.opera.com/opera stable non-free
#deb http://deb.opera.com/opera-beta stable non-free
The repositories are configured in the file /etc/apt/sources.list. Open the file with an editor such as vi vi /etc/apt/sources.list
Summary of vi command keys for adding the text:
i – insert
a – append from cursor position
dd – delete line
<escape> – stop entering content
:w – write the file
:q – quit leave the file
Updating System apt Status
The apt package manager uses keys to help maintain the security of packages. Opera’s keys need to be added:
gpg –keyserver subkeys.pgp.net –recv-key 6A423791
gpg –fingerprint 6A423791
gpg –armor –export 6A423791| apt-key add –
Having updated the sources.list file apt needs to be updated with these details apt-get update
Installing Opera
Opera is then installed with apt-get install opera
