Issue

• I use a custom repository and get yum errors, how can I use the yum output to solve the problem?
• Yum refuses to update packages, reporting a dependency being required, but the dependency is already installed
• Yum update fails with a "missing dependency" error similar to the following:

Missing Dependency: package1 = 2:4.11 is needed by package 2:package2.i386 (rhel-i386-server-5)

or

Missing Dependency: /lib64/security/pam_loginuid.so is needed by package openssh-server-4.3p2-82.el5.x86_64 (installed)
Error: Missing Dependency: /lib64/security/pam_loginuid.so is needed by package openssh-server-4.3p2-82.el5.x86_64 (installed)

• Yum refuses to install an update because of an installed package whose dependencies the update would break :
