How to check if dpkg-architecture --list has all the architectures?

To install skype and dependencies on 16.04. 64bit I need to

sudo dpkg --add-architecture i386

Via (man page):

dpkg-architecture --list

I then can check the list of architectures. What line must be in there to be sure that the first command was executed correctly?

My problem is that I cannot install Skype and I suspect the architecture was not updated correctly. I also suspect this might somehow relate to my installation of Wine.

I answer my own question because I just found out via

dpkg --print-foreign-architectures

which printed

i386

that obviously multiarch is/was enabled.
