SOLVED - Installing Opera

[teedee]

How do I install Opera on my wattOS?

I need it because nor Firefox or Iceweasel do not render Google Analytics website. It is displayed only on half of page (vertical). I need 2 browsers for my everyday use because I have two Google accounts and it is annoying to log in and out on one browser. Best solution is to have two browsers permanently logged in. That's what I do on my other laptop.

When I try to install Opera on wattOS, using Debian package from this site http://www.opera.com/download/guide/?os=linux I get error on GDebi saying about amd64 error.

Other methods don't work as well. Manual installation using archive ends up with a message, that Opera package cannot be found. The same happens when I try to install from Debian repository.

How do I install it?

I tried installation of Opera in wattOS R8 LXDE. It was possible for result normalcy.

teedee tried downloading is a page for Opera 64bit version:
http://www.opera.com/download/guide/?os=linux

Please download it from this  if wattOS using is for Opera 32 bit version:
http://www.opera.com/download/guide/?os=linux-i386&list=all

In addition, Microwatt is included in a 32 bit version, too.

Thanks BALLOON it works with some help. Installing opera_12.16.1860_i386.deb via GDebi fails because of missing packages. I had to install it manually using:

sudo dpkg -i opera_12.16.1860_i386.deb

and then

sudo apt-get -f install

and now it works!

BTW
My problem was, that I expected my machine to be x86 architecture. I'm used to Windows naming convention and Windows XP originally installed on my netbook was x86 (32-bit in MS language). Acronym of i386 in MS language refers to old Pentium processors.
You are right, I kept downloading amd64 (opera_12.16.1860_amd64.deb) file.

What is the meaning of x86 and i386 in Linux world?
