How do I upgrade 32 bit to 64?

[hai3]

I just installed Ubuntu last Sunday. I downloaded the iso by clicking download button on YUMI. I though i was 64bit. I just installed some 64bit software and it wont run!!! I checked and i saw i have a 32 bit OS!!!! I WANNA UPGRADE IT TO 64 NOW!!!!

Clean install. There is no upgrade from 32bit to 64bit.

Save all data, download 64bit ISO, create install media, boot from it, install. That's it. ;)

I am an idiot. I need to be in asylum...

Btw the iso i downloaded end with "amd64" why is it install 32?

I would suggest downloading from a site like this (http://www.ubuntu.com/download/desktop) only.

Why are you so sure that it is a 32bit OS? When I run this command


uname -a

I see this result


3.16.0-6-generic #11-Ubuntu SMP Mon Jul 28 01:59:56 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

Your kernel will be different but if you see x86_64 then it is 64 bit Ubuntu and perhaps there is another reason why those applications will not run.

There is this. Check with 'uname -r' in a terminal, as advised ...

There you go, it's a 32 bit OS
For your reference
x86_64 ==> 64-bit kernel
i686 ==> 32-bit kernel

Like the slickymaster states, 32bit. Please reinstall using a 64bit image. There is no way of upgrading 32bit to 64bit.
