rpm & cpp problem
Hi,stupid question with hopefully easy solution

I tried to install cpp-3.2-7.i386.rpm via rpm, but it always ended up with the following error message:
Code:
[root@server]# rpm -i cpp-3.2-7.i386.rpm error: cpp-3.2-7.i386.rpm: V3 DSA signature: BAD, key ID db42a60e error: cpp-3.2-7.i386.rpm cannot be installed
Any ideas welcome
