What are the possible options for the --arch option in debootstrap?

I need to set the arch option in debootstrap. So I did some research and read the manual.



After reading the manual I see that the section on the options simply says
--arch=ARCH
Implying that I should know the correct syntax for the architecture I need.
I don't. I need 64 bit architecture.
I know that "i386" can be used for 32bit architecture.
What should I set the --arch option to if I want 64 bit architecture?
Or more generally what would the range of options be?



I could guess (but don't know and can't determine) that potentially the range or arch options depends on the OS being booted. In my case its a version of ubuntu that I know should work in 64bit. So the question becomes how would I determine the 64bit architecture option syntax?



I could further guess (but again don't know and can't determine) that the option syntaxes are actually supplied by the booted OS and if I knew where to look I could figure it out. In which case, where would I look?

          The possible values are the codenames of the architectures supported by the target operating system. See the installation guide for Ubuntu: for 64-bit x86, the appropriate value is amd64.



          On systems with dpkg,



          dpkg --print-architecture


          will show the current architecture (which is the default architecture for debootstrap).



          debootstrap is also capable of installing a system for any supported architecture, not only the host system’s architecture; see its --foreign option. If necessary it can use Qemu to emulate the target architecture.

          • Great thanks! I note also that it is case sensitive and thus AMD64 is NOT correct in this example.
