We are using Fedora Core 4 x64 edition, and the supplied version of Samba is 3.0.14a-2. When we attempt to upgrade to any version above 14a-2, it says "A newer version is already installed."
What do we need to do in order that we may install .21c ?
One problem I've seen people have when upgrading Samba on x86_64 machines is that there are frequently both 32-bit and 64-bit versions of the libraries installed. If they attempt to only upgrade the 64-bit packages, rpm gets a bit testy about it. The solution is to upgrade both the 32-bit and 64-bit packages at the same time. Precisely how to do that depends on where you're getting the packages from.
I only build 32-bit packages on samba.org. You should probably
rebuild the SRPM on your system.
