Hello, This is my first post here and my first time administering Fedora, though I have some experience with Debian/Ubuntu. I'm setting up an EC2 based Fedora Core 6 installation on a 64-bit platform (EC2 large instance). After setting up a basic Apache, Ruby, MySQL configuration, I've run into problems trying to install development tools using yum. For example, if I run: # yum groupinstall 'Development Tools' I get errors: Package gcc - 4.1.2-13.fc6.x86_64 already installed and latest version Package pkgconfig - 1:0.21-1.fc6.x86_64 already installed and latest version Package gcc-c++ - 4.1.2-13.fc6.x86_64 already installed and latest version Package binutils - 2.17.50.0.6-5.fc6.x86_64 already installed and latest version Package subversion - 1.4.3-2.fc6.x86_64 already installed and latest version Error: Unable to satisfy dependencies Error: Package rpm-libs needs rpm = 4.4.2.1-1.fc6, this is not available. I'm interpreting this error as meaning that I nead rpm-libs 4.4.2.1-1.fc6 . The closest package I can find is rpm-libs-4.4.2.1-2.fc6.x86_64.rpm, but this also gives errors: # rpm -i rpm-libs-4.4.2.1-2.fc6.x86_64.rpm error: Failed dependencies: rpm = 4.4.2.1-2.fc6 is needed by rpm-libs-4.4.2.1-2.fc6.x86_64 So it looks as if I am missing the required rpm-libs package. Is this correct? If so, how can I rectify this? Thanks in advance for the help. Cheers, -- Nick Black -------------------------------- http://www.blacksworld.net
