[Bug 829205] Re: multiarch environment makes testing of new package version for developers very awkward

[Steve Langasek]

I'm sorry, but the issue you describe here is a consequence of a
fundamental design requirement of multiarch; this is not something
that's going to be changed.

This is not about checking the file contents at all, it's about the fact
that all architectures of a package must be at the same version in order
to be configured.  Yes, this means more work to do test builds of a
package if you are going to do your test installing on a system that has
foreign-arch copies of the library installed.  The only thing I can
suggest is to do your package testing in a clean environment to avoid
this - one without flashplugin or skype installed (the only two
applications that use multiarch currently).

Title:
  multiarch environment makes testing of new package version for
  developers very awkward

Status in “dpkg” package in Ubuntu:
  Won't Fix

Bug description:
  In the new multiarch environment there is both the amd64 and the i386
  version of each multiarch library installed. The two versions of the
  libreary have to be from exactly the same package build from buildds
  which is checked by whether the files in /usr/share/doc/<package>/ are
  identical.

  If I do development work for Ubuntu, modifying a source package
  bumping the version number, and then building and installing this
  package on my system so that I can test it before uploading, the
  install fails in the configure part with

  dpkg: error processing libcups2 (--install):
   libcups2:amd64 1.5.0-4 cannot be configured because libcups2:i386 is in a different version (1.5.0-3)
  dpkg: error processing libcups2:i386 (--install):
   libcups2:i386 1.5.0-3 cannot be configured because libcups2:amd64 is in a different version (1.5.0-4)

  The only way to get my new package installed is to remove the i386
  library with --force-depends:

  sudo dpkg -P --force-depends libcups2:i386

  Then I can install and test my new package version but my system is
  inconsistent, preventing me from being able to use apt-get to update
  the system or to install other packages.
