Why can't I install 'arm64' packages on an 'amd64' system when I can install 'armhf' packages?

Pretty self-explanatory: could someone tell me why I get the error



$ sudo apt-get install gcc-6-base:arm64
dpkg: error processing archive /var/cache/apt/archives/gcc-6-base_6.0.1-0ubuntu1_arm64.deb (--unpack):
package architecture (arm64) does not match system (amd64)
Errors were encountered while processing:
/var/cache/apt/archives/gcc-6-base_6.0.1-0ubuntu1_arm64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)


when



$ sudo apt-get install gcc-6-base:armhf
Selecting previously unselected package gcc-6-base:armhf.

works just fine on my AMD64 system? How do I fix this?

          Never mind, I figured it out. You need to run:



          sudo dpkg --add-architecture arm64


          And you can see the list of existing architectures added via:



          sudo dpkg --print-foreign-architectures


          Why they think the user must be initially joking about the explicit :arm64 suffix is beyond me. It's not like you don't already have to explicilty add arm64 as an architecture in /etc/sources.list...
