When you add a package to an installed system and the installation fails, there is no way to know what failed. All you get is an "installation failed" message next to the package name. A link to get the log output would help troubleshooting.
More details can be added to the Packages pane based on the information that we receive back from pulp; however, in the meantime, the information that is currently available can be viewed from the system event history. E.g. navigate to: Systems => [system X] => highlight Details => select Events From here, you can see history of all actions performed on the system from the server.
