I am unable to reproduce this problem on my machine, so we will have to
debug it on our system.
First of all, is your system ok? Random segfaults could come for a
kernel that started to oops. You can have a look to the output of
Then, it would be nice to know which program in the posrtm/preinst fail.
You can try to look at the output of "dmesg", sometimes programs that
segfault are written there. If this is not the case, you can change the
first line of /var/lib/dpkg/info/libc6.postrm from
! /bin/sh -x
, try to upgrade again and send me the output.
Finally it would be nice if you acn send me the output of "ldd
/bin/bash", so that we can see which version of the libc are you using
(linuxthreads, nptl, nptl i686 or xen).
