I had an almost idendical problem on 6.06 LTS, but the broken links were
/etc/rc2.d/S91samba -> /samba /etc/rc3.d/S91samba -> /samba
Obviously, there's no 'samba' in the root folder, so I just deleted these dud links, ran "apt-get upgrade -f" and it seemed to resolve itself.
Maybe one of the recent packages was dodgy.
