Comment 8 for bug 296499

Hamado1,

Your circumstances are special, because you have already installed the package, and the postrm and init scripts will keep failing and prevent you from un-installing the package (and possibly upgrading).

You need to edit these two scripts in your file system:

/etc/init.d/havp
/var/lib/dpkg/info/havp.postrm

In both files, find the lines that contain "umount", and change that to "umount -l" -- or if that doesn't work either, simply remove or comment-out those lines.
