Bug#358059: libc6-i386: Can't install package on amd64 arch

[Olivier VItrat <olivier.vitrat@sympatico.ca>]

Package: libc6-i386
Version: 2.3.6-3
Severity: normal

I can't install libc6-i386 package on amd64 arch.

Dépaquetage de libc6-i386 (à partir de .../libc6-i386_2.3.6-3_amd64.deb) ...
dpkg : erreur de traitement 
de /var/cache/apt/archives/libc6-i386_2.3.6-3_amd64.deb (--unpack) :
 tentative de remplacement de « /lib/ld-linux.so.2 », qui appartient aussi au 
paquet ia32-libc6
 Des erreurs ont été rencontrées pendant l'exécution :
  /var/cache/apt/archives/libc6-i386_2.3.6-3_amd64.deb
  E: Sub-process /usr/bin/dpkg returned an error code (1)

(translation: file /lib/ld-linux.so.2 is also in ia32-libc6)

file ia32-libc6 is:

ia32-libc6:
