error: architecture name in specifier is illegal: must start with an alphanumeric

[Sebastien Bacher]

Using current precise, that happens when trying to sudo apt-get remove --purge a package which is in 'rc' state

[Launchpad Janitor (janitor)]

This bug was fixed in the package apt - 0.8.16~exp12ubuntu2

---------------
apt (0.8.16~exp12ubuntu2) precise; urgency=low

  [ David Kalnischkies ]
  * apt-pkg/deb/dpkgpm.cc:
    - chroot if needed before dpkg --assert-multi-arch
    - ensure that dpkg binary doesn't have the chroot-directory prefixed
  * apt-pkg/depcache.cc:
    - if a M-A:same package is marked for reinstall, mark all it's installed
      silbings for reinstallation as well (LP: #859188)
  * apt-pkg/contrib/configuration.cc:
    - do not stop parent transversal in FindDir if the value is empty
  * methods/http{s,}.cc:
    - if a file without an extension is requested send an 'Accept: text/*'
      header to avoid that the server chooses unsupported compressed files
      in a content-negotation attempt (Closes: #657560)
  * apt-pkg/aptconfiguration.cc:
    - chroot if needed before calling dpkg --print-foreign-architectures

  [ Michael Vogt ]
  * apt-pkg/deb/dpkgpm.cc:
    - fix crash when a package is in removed but residual config state
      (LP: #923807)
