When I download ubuntu, it always gives me an image for amd...
Like ubuntu-18.04-desktop-amd64.iso
Where can I find an download for Intel?
I try to install that through Oracle VirtualBox so maybe I am doing something wrong in the virtual machine I create...
This is for Intel too. The amd64 mean that this image is for 64-bit architecture.

Of corse you can download all releases from this link too: http://releases.ubuntu.com/
