Greetings, This is a new install on CentOs 4.1 dvd from a couple weeks ago. The initial yum updates worked fine but now There are about 15 things that get dependency errors and yum will not install the updates. Rebuild the RPM database, removed /var/cache/yum/* , yum update yum for the latest version and the errors still exist. When you query the rpm database the dependency are installed. Here are some examples: # yum install gtkhtml3 Setting up Install Process Setting up repositories update 100% |=========================| 951 B 00:00 base 100% |=========================| 1.1 kB 00:00 addons 100% |=========================| 951 B 00:00 extras 100% |=========================| 1.1 kB 00:00 Reading repository metadata in from local files Parsing package install arguments Resolving Dependencies --> Populating transaction set with selected packages.
