Bug Tracker Information for Emacs

How to Report a Bug in Emacs

The best way to report a bug in Emacs is to use the command
M-x report-emacs-bug
from inside Emacs. This helps you construct a mail with useful information about your Emacs session, and send it to the right address. If you cannot send mail from Emacs for some reason, you can send your report to bug-gnu-emacs@gnu.org. Submissions are moderated, so there may be a delay before your report appears.

For more information, please read the section Reporting Bugs in the Emacs manual. You do not need to know the details of how this bug tracker works in order to report bugs, but if you want to, you can read more about this tracker.

Bug reports are sent to the bug-gnu-emacs mailing list. Please try and search the list archives before posting to see if someone has already posted your issue.

If you want to send a copy of your initial report to someone else, please use an X-Debbugs-CC header rather than plain CC, as explained in more detail here.

Replying to an Existing Report

To reply to an existing report, for example #123, send mail to 123@debbugs.gnu.org. Or to the bug-gnu-emacs mailing list, but be sure to keep "bug#123" in the subject, else you will create a new report.

If a report is closed and receives no more mail for one month, it is archived. Before you can send more mail to it, you must send the command "unarchive 123" in the body of a message to the control server address.

Viewing Bug Reports

You can read all Emacs reports at the bug-gnu-emacs mailing list, or you can search or browse this tracker.

Documentation about the Bug Tracking System

See the more detailed information.

Emacs developers can read more about how to use this tracker in the file admin/notes/bugtracker in the Emacs repository.


A few Emacs "sub-packages" exist, for major components of Emacs with their own bug mailing lists. You do not have to use these packages, but can if you like. You can either use e.g. "Package: emacs,gnus" (if your report is for the version of Gnus that comes with Emacs) or just "Package: gnus". The former sends your report to two mailing lists, the latter just to one.

Name Address
cc-mode bug-cc-mode AT gnu.org
gnus bugs AT gnus.org
org-mode emacs-orgmode AT gnu.org
