When working with Fedora Packaging, you may run across issues in packages, with the buildsystem, with policies or process, or with any number of other things. Here are some basic guidelines to assist you in reporting such issues to the right people.
Any issue that requires direct work on Fedora’s infrastructure should be reported using the Fedora Infrastructure issue tracker. This would include frozen or failing build systems.
For issues within packages, see How to File a Bug. This would include typical build errors.
Any questions about policy or processes should be reported to the devel mailing list. This would include questions of spec design, naming conventions or review concerns.
If ever you are unsure about which system to use, feel free to report to whichever system seems best to you. Your report can be redirected as needed.
