>From the Logwatch email message, I deduced that yum was not performing nightly updates. A check in yum.log confirmed this. So I tried doing a yum update by hand. I got the following errors reported: Error: Missing Dependency: commons-modeler = 1.0-8 is needed by package commons-modeler-devel Error: Missing Dependency: commons-digester = 1.4.1-13 is needed by package commons-digester-devel Error: Missing Dependency: commons-fileupload = 1.0-8 is needed by package commons-fileupload-devel Error: Missing Dependency: commons-collections = 2.1-12 is needed by package commons-collections-devel Error: Missing Dependency: commons-pool = 1.1-3 is needed by package commons-pool-devel Error: Missing Dependency: commons-beanutils = 1.6.1-13 is needed by package commons-beanutils-devel Error: Missing Dependency: commons-dbcp = 1.1-3 is needed by package commons-dbcp-devel 1) How can missing dependencies arise like this? 2) What should I do to correct the situation? (Erasing commons-modeler-devel et. al. seems logical, but I can't think why they are there in the first place) 3) Why don't I get notified by email that there was a problem with the nightly updates? -- Colin Adams Preston Lancashire
