I was able to get around it.
Looking for what the user snmp was doing I found
$~> ps auxf|grep [s]nmp snmp 1129 0.0 0.0 10384 296 ? Ss 14:19 0:00 rpc.statd -L
After
$~> sudo /etc/init.d/statd stop
the process was gone and the user 'snmp' did no longer own any process and
$~> sudo dpkg --configure -a
completet without errors.
