Debian 8 -- Reporting Problems
Errors in the Release Notes should be reported as bug against the pseudo-package release-notes. Discussion of that document is coordinated through the debian-doc mailinglist at <email@example.com>. If you have issues with the document which aren't appropriate for a bug you should probably mail the list instead.
If you have a problem with the installation system, please report bugs against the installation-reports package. Fill out the report template to ensure you include all the necessary information.
If you have issues with the installation system which aren't appropriate for a bug (e.g., you're not sure if it's truly a bug or not, the offending piece of the system is unclear, etc.) you should probably send an email to the mailing list, <firstname.lastname@example.org>.
If you have problems when upgrading your system from previous releases, please file a bug against the upgrade-reports package, which is the pseudo-package used to track that information. For more information on how to submit upgrade reports, please read the Release Notes.
If you have problems with the system after installation, you should try to track down the offending package and file a bug against that package.
