Bug#455974: libc6: Upgrade to libc 2.7-3 breaking of dpkg

[bluesdog <bluesdog@gmail.com>]

Similar to the OP, but perhaps somewhat different also.  Recent upgrade
to libc6 2.7-3 borked dpkg, which then reported libc6 was not completely
installed.

The error message complained about the /var/lib/dpkg/info/libc6.postinst
script, so I renamed the script temporarily, and ran dpkg-reconfigure libc6.

This forced libc6 to install, but a couple of other packages also then
failed, with similar /var/lib/dpkd/info postinst script complaints

Fix was to reconfigure dpkg to use dialog frontend, using the f switch, as:

# dpkg-reconfigure -f dialog

I then renamed the various /var/lib/dpkg/info scripts back to the
original nomenlature, and ran dpkg-reconfigure on the offending packages

Apologies if this is not the same problem, but since it occurred with
libc6 upgrade, I thought it might be relevant.
