Title:
  dselect error: foreign architectures enabled but multi-arch is not
  supported

Status in “dpkg” package in Ubuntu:
  Confirmed
Status in “dpkg” package in Debian:
  New

Bug description:
  LANG=C ; dselect select
  dselect: error: foreign architectures enabled but multi-arch is not supported

  Maybe we should add "Please try another package manager for now. For example aptitude or .." to the error message.
  Or should we remove package dselect completely from amd64 arch if it is not able to handle it?

  Bug or feature request to add multi-arch support to dselect and what
  to do if you want to continue using it.

  lsb_release -rd
  Description:    Ubuntu 12.10

  "The selection code does not support multi-arch at all, so do not even try to run it if there's a foreign architecture configured."

  OK so if I reverse the patch it is working as before in precise.
  mulit-arch selection is not working great but at least it can do other
  things like before quantal 12.10.

  To rebuild..
  apt-get source dselect
  Reverse patch in dselect/main.cc
  dpkg-buildpackage -b -us -uc
  dpkg -i dpkg -i dselect_*.deb
