can not downgrade debian packages

Hello all :)

I m just trying to install openssi and have Problems downgrading the packages. 
Its a full patched debian3.1 in a vmware-server.
I followed install instruction with both version 1.2 and 1.9 till apt-get 
dist-upgrade then I have to remove this packages!

  apt apt-utils aptitude at base-files bash bsdmainutils console-common
  console-tools cpio cramfsprogs cron dash debian-archive-keyring discover1
  dmidecode e2fslibs e2fsprogs ed eject exim4 exim4-base exim4-daemon-light
  fdutils gettext-base gnupg gpgv groff-base grub hotplug info initrd-tools
  initscripts ipchains iptables kernel-image-2.6.8-3-386 klogd laptop-detect
  libapt-pkg-perl libblkid1 libbz2-1.0 libcomerr2 libconsole libdb1-compat
  libdb3 libdb4.2 libdb4.4 libdevmapper1.02 libdiscover1 libedit2 libfribidi0
  libgcrypt11 libgdbm3 libgnutls11 libgnutls13 libgpg-error0 libgpmg1 libkrb53
  libldap2 liblockfile1 liblzo1 libncursesw5 libnewt0.52 libopencdk8
  libpcap0.7 libpcap0.8 libpci2 libpcre3 libpopt0 libreadline5 libsasl2-2
  libsasl2-modules libsigc++-1.2-5c102 libsigc++-2.0-0c2a libslang2 libss2
  libssl0.9.7 libssl0.9.8 libstdc++5 libtasn1-2 libtasn1-3 libtextwrap1
  libusb-0.1-4 libuuid1 libwrap0 locales localization-config logrotate mailx
  man-db mawk modconf module-init-tools modutils mount nano netbase nvi

  pppoeconf procps psmisc slang1a-utf8 ssh sysklogd sysvinit tasksel
  tasksel-data tcpd telnet usbutils util-linux wget whiptail zlib1g


And I shall type: yes, I know what I do!

So, this is not running

doing apt-get upgrade then I have a broken pipe with
/var/cache/apt/archives/libuuid1_1.35-6.ssi1_i386.deb

Im not able to downgrade the packages.

can someone help?
