From log:

insserv: loop involving service dns-clean at depth 1
insserv: Starting smfpd depends on rc.local and therefore on system facility `$all' which can not be true!
insserv: exiting now without changing boot order!
update-rc.d: error: insserv rejected the script header
dpkg: error processing package openssh-server (--configure):
 subprocess installed post-installation script returned error exit status 1
