[Bug 1123034] Re: "dpkg --add-architecture" not implemented in Ubuntu 12.04.1 LTS

[Raphaël Hertzog]

Ubuntu 12.04 has an earlier implementation of multiarch where it uses
the --foreign-architecture options that you see in
/etc/dpkg/dpkg.cfg.d/multiarch. Newer versions of ubuntu have the latest
multiarch implementation where dpkg --add-architecture is supported.

This is not a bug. I don't know what you expect. In any case, the new
multiarch implementation won't be deployed to LTS 12.04 at this point.

** Changed in: dpkg (Ubuntu)

Title:
  "dpkg --add-architecture" not implemented in Ubuntu 12.04.1 LTS

Status in “dpkg” package in Ubuntu:
  Invalid

Bug description:
  According to "Multiarch/Implementation" on Debian Wiki
  http://wiki.debian.org/Multiarch/Implementation

  Ubuntu 12.04 LTS should use the command

  sudo dpkg --add-architecture

  to add foreign architectures .. if some user wants..

  sudo dpkg --add-architecture i386

  returns

  dpkg: error: unknown option --add-architecture

  Type dpkg --help for help about installing and deinstalling packages [*];
  Use `dselect' or `aptitude' for user-friendly package management;
  Type dpkg -Dhelp for a list of dpkg debug flag values;
  Type dpkg --force-help for a list of forcing options;
  Type dpkg-deb --help for help about manipulating *.deb files;

  Options marked [*] produce a lot of output - pipe it through `less' or
  `more' !


  
  So why this command not exist in dpkg in Ubuntu 12.04.1 LTS ?
  I know that I can add a foreign architecture via /etc/dpkg/dpkg.cfg.d/multiarch
  but just asking about the command..
