Hi,

I just move from BT4B to BT4Pre (yes I did a new install). I am following the instructions on how to update to the latest packages so I have done:
apt-get update
apt-get upgrade
apt-get dist-upgrade

which gave me the following messages:
Unpacking libssh2 (from .../libssh2_1.2.2-bt0_all.deb) ...
dpkg: error processing /var/cache/apt/archives/libssh2_1.2.2-bt0_all.deb (--unpack):
trying to overwrite `/usr/lib/libssh2.so.1', which is also in package libssh2-1

I did a quick google and found I should do
apt-get -f install

which fixed the libssh issue however the scapy issue remains
