Steps to try and fix (with no sucess):
1. upgrade from 0.5.0 to 0.5.3
2. try same image on different computers (NFS-Root). I think
chroot should be most reliable. In any case I get the same error
everywhere.
3. tried combinations of -s, install, and -d, but always get the same error.
4. created an /etc/apt/preferences file. Same as what is used on
a working system:
Package: autoconf
Pin: release a=stable
Pin-Priority: 1001
Package: automake
Pin: release a=stable
Pin-Priority: 1001
Package: libtool
Pin: release a=stable
Pin-Priority: 1001
Package: *
Pin: release a=stable
Pin-Priority: 600
Package: *
Pin: release a=potato
Pin-Priority: 600
Package: *
Pin: release o=helix
Pin-Priority: 700
Possibly something is currupt on this root directory, but I don't
know what (everything looks OK to me), and even if that is the
case, apt-get should not segfault.
I think I saw something at one stage with apt-get from stable about the
status file being currupt. I looked at that file, and it looks fine.
Nor does dpkg have any problems accessing it. I can send it to you on
request. However, I think it might be just a false lead.
