Hello, I am new to Linux/Unix and new to FC5. I have run PUP several time over the past few weeks, and all went well. Yesterday, however, I received a Dependency Resolution error. So I decided to try YUM (actually Yum Extender), but got the same error. "Missing Dependency: geronimo-specs = 1.0-0.M2.2jpp_7fc is needed by package geronimo-specs-compat" I don't think this is important to me right now, but it raises the question. What should I do in this case? I do not know how to control the different repositories searched, but there are a lot of listings in /etc/yum.repos.d. Thanks, Bob
