[otrs] Update SuSE 7.3

Hello, I try to upgrade my SuSE 7.3 version of OTRS to 1.0. First I stop all running services, then I do 'rpm -Uhv otrs-1.0.0-RC1.i386.rpm' but this command doesn't find an end. Nothing happens in the shellor elsewhere. When I kill the command, I can restart the old version without problems. Any hints ? Christoph
