I have Ubuntu:

Ubuntu 12.04.1 LTS

This is output of cat /proc/cpuinfo:

This is output of dpkg --version:

Debian `dpkg' package management program version (i386).

Despite dpkg is compiled for i386, it seems I have Amd64 as a processor. But when I install Java:

sudo dpkg -i sun-java6-bin_6-06-0ubuntu1_amd64.deb 

I have this error:

dpkg: error processing sun-java6-bin_6-06-0ubuntu1_amd64.deb (--install):
 package architecture (amd64) does not match system (i386)
Errors were encountered while processing:

Any ideas?

I am afraid you are trying to install a 64-bit deb on a 32-bit operating system which is not possible.

Download the appropriate 32-bit deb file and then try to install it. Also note that the linked deb file was packaged for Hardy (8.04) and can very well open you up for security threats given how outdated the package is and the withdrawal of any future security updates for Sun Java from Oracle.

But I have: "model name : AMD Athlon(tm) 64 Processor 3400+" in /proc/cpuinfo ... – Rodnower Sep 22 '12 at 14:05
What matters is not what your computer can do but what architecture you have installed. What did you get for uname -m? – jokerdino Sep 22 '12 at 14:07
i686 OK, I see :) Thank you. – Rodnower Sep 22 '12 at 14:19
