I am having problems trying to update the packages on my FC2 x86_64 system with either yum or up2date. [Up2date section] I resolved the header message by following the advice given on this list and deleting the header and rpm files from /var/spool/up2date. Now when I run up2date -u, the following output is produced (see bottom of message for yum info): Testing package set / solving RPM inter-dependencies... /etc/security/selinux/file_contexts: No such file or directory ######################################## RPM package conflict error. The message was: Test install failed because of package conflicts: The following packages were added to your selection to satisfy dependencies: Name Version Release -------------------------------------------------------------- xorg-x11-libs 6.7.0 5 xorg-x11-libs 6.7.0 5 package xorg-x11-libs-6.7.0-5 is already installed [root@Linux64 law]# [Yum Section] Not wanting to be closed minded, I tried yum. Output is: [root@Linux64 law]# yum update Gathering header information file(s) from server(s) Server: Fedora Core 2 - x86_64 - Base Server: Fedora Core 2 - x86_64 - Extras Server: Fedora Core 2 - x86_64 - Released Updates Finding updated packages Downloading needed headers Resolving dependencies ....Unable to satisfy dependencies Package mozilla-devel needs mozilla-nspr-devel = 37:1.6-8, this is not available.

Package mozilla-devel needs mozilla-nss-devel = 37:1.4.1-18, this is not available. Package mozilla-devel needs mozilla = 37:1.6-8, this is not available. [root@Linux64 law]# BUT.....
