I tried to install and older version of libc6 from the snapshot repository but that didn't work. I kept getting the segfault. Here is what I did that finally worked:
as root # /var/lib/dpkg/info/libc6-i686:i386.postinst configure # dpkg --configure libc6 # apt-get -f install # dpkg --configure -a I don't know if all of those steps were required but it took care of the problem. On my other machine that is broken, it is segfaulting in the pre-install. That machine is a 64bit amd computer. I haven't figured out a way to fix it yet. Brent
