[Bug 902603] Re: When installing Multi-Arch: same (meta-)package for two architectures, dpkg considers one arch as completely disappeared

[Martin Pitt]

While it works with the original test case now:

  sudo apt-get install --reinstall libpthread-stubs0{,:i386} libpthread-
stubs0-dev

it still fails when you do it separately:

$ LANG= sudo apt-get install --reinstall libpthread-stubs0{,:i386} libpthread-stubs0-dev
[...]
The following NEW packages will be installed:
  libpthread-stubs0:i386
Preparing to replace libpthread-stubs0 0.3-2.1ubuntu1 (using .../libpthread-stubs0_0.3-2.1ubuntu1_amd64.deb) ...
Unpacking replacement libpthread-stubs0 ...
Selecting previously unselected package libpthread-stubs0:i386.
Unpacking libpthread-stubs0:i386 (from .../libpthread-stubs0_0.3-2.1ubuntu1_i386.deb) ...
Preparing to replace libpthread-stubs0-dev 0.3-2.1ubuntu1 (using .../libpthread-stubs0-dev_0.3-2.1ubuntu1_amd64.deb) ...
Unpacking replacement libpthread-stubs0-dev ...
Setting up libpthread-stubs0 (0.3-2.1ubuntu1) ...
Setting up libpthread-stubs0:i386 (0.3-2.1ubuntu1) ...
Setting up libpthread-stubs0-dev (0.3-2.1ubuntu1) ...

$ LANG= sudo apt-get install --reinstall libpthread-stubs0-dev
[...]
Preparing to replace libpthread-stubs0-dev 0.3-2.1ubuntu1 (using .../libpthread-stubs0-dev_0.3-2.1ubuntu1_amd64.deb) ...
Unpacking replacement libpthread-stubs0-dev ...
(Noting disappearance of libpthread-stubs0:i386, which has been completely replaced.)
Setting up libpthread-stubs0-dev (0.3-2.1ubuntu1) ...
The following package disappeared from your system as
all files have been overwritten by other packages:
  libpthread-stubs0
Note: This is done automatic and on purpose by dpkg.
