[Bug 1032250] Re: apt chooses wrong architecture if sources.list contains arch-qualified entries

[Wookey]

This bug does not seem to be present in apt 0.9.7.3 in debian unstable. There it works as expected.
Similarly for apt 0.9.7.1 in debian testing. So this wqould appear to be something in the ubuntu patches.

Title:
  apt chooses wrong architecture if sources.list contains arch-qualified
  entries

Status in “apt” package in Ubuntu:
  New

Bug description:
  If both armel and armhf are given as arch qualifiers in sources.list,
  then apt tries to install the wrong architecture package:

  I ask directly for an amrhf package and apt tries (but fails) to
  install an armel one:

  $ sudo apt-get install zlib1g-dev:armhf
  ...
  The following packages have unmet dependencies:
   zlib1g-dev:armel : Depends: zlib1g:armel (= 1:1.2.7.dfsg-13) but it is not going to be installed
                      Depends: libc6-dev:armel but it is not going to be installed or
                               libc-dev:armel

  Sources.list looks like this:
  deb [arch=amd64,i386] http://archive.ubuntu.com/ubuntu quantal main universe
  deb [arch=armhf,armel] http://ports.ubuntu.com/ubuntu-ports quantal main universe
  deb-src  http://archive.ubuntu.com/ubuntu quantal main universe

  There are no :armel or :armhf packages installed.

  The ordering of the arch qualifiers in sources.list does not matter: this line produces the same output
  deb [arch=armel,armhf] http://ports.ubuntu.com/ubuntu-ports quantal main universe

  change the line to 
  deb [arch=armhf] http://ports.ubuntu.com/ubuntu-ports quantal main universe
  and it works as expected.

  The apt sources info seems to be overriding the dpkg foreign-
  architecture info.
