Marty has been a good help to help me reinstall the guile-1.6 package,
but I could not remove it either since the postrm script was corrupted,
too. Here's a way I thought of to force apt to reinstall a package you
think might have been corrupted along the install process.
apt-get autoclean ; apt-get -d --reinstal $PACKAGE_NAME ;
cd /var/cache/apt/archives ; dpkg -i --force-all $PACKAGE_FILE.
One caveat : I'm assuming here that the source of your problem was some
kind of corruption and that the package would install properly (no
dependencies problems, etc) in normal times; the --force-all might be a
bit risky otherwise.
