Hi, I am setting up a yum repository for our applications and I am having a bit of trouble. I copy the files to a webserver, run createrepo and then configure the servers to use it. One of the RPMs is a "release" package that includes exact versions of all the binary and configuration files as dependencies so we can do "packaged releases" and, if we want to revert to a previous version, we can force it by installing this package (and the yum-downgrade plugin). The issue I am having is that RPM/yum seems to be unable to correctly resolve the dependencies: If I do "yum install adm-release" I get errors about lots of missing dependencies. EG: [root at host01 yum.repos.d]# yum install adm-release Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile Setting up Install Process Resolving Dependencies --> Running transaction check ---> Package adm-release.noarch 0:1-1 set to be updated --> Processing Dependency: adm-app-conf-18-2010.09.01 for package: adm-release --> Processing Dependency: ant-1.8.1-1 for package: adm-release --> Processing Dependency: jdk-1.6.0_20-2.0 for package: adm-release .... --> Finished Dependency Resolution adm-release-1-1.noarch from myrepo has depsolving problems --> Missing Dependency: jdk-1.6.0_20-2.0 is needed by package adm-release-1-1.noarch (myrepo) adm-release-1-1.noarch from myrepo has depsolving problems --> Missing Dependency: adm-app-conf-18-2010.09.01 is needed by package adm-release-1-1.noarch (myrepo) adm-release-1-1.noarch from myrepo has depsolving problems --> Missing Dependency: ant-1.8.1-1 is needed by package adm-release-1-1.noarch (myrepo) adm-release-1-1.noarch from myrepo has depsolving problems --> Missing Dependency: geosweep-libquantis-0.1.0-1.1 is needed by package adm-release-1-1.noarch (myrepo) ....

I am quite baffled and would like to get this to work as soon as possible. Thanks Gabriel
