Yeah, that’s really annoying. You have to make sure you have an active bugzilla API key before ABRT can create a bug. Login to https://bugzilla.redhat.com/, choose the drop-down menu on your name in the upper right-hand corner, and choose Preferences. You should see a horizontal list of categories. The fifth from the left is API Keys; choose that. From here you can manage your API keys, or create a new one if you don’t have any.
Once you have an API key, in ABRT, choose the hamburger menu in the upper right, and select Preferences. In the popup box, choose the Configure button in the lower right. That will pop up another box, with “uReport” and “Bugzilla” on the left. Choose Bugzilla. There is a box there where you can paste your bugzilla API key.
There you go. How to make ABRT work in only 42 easy steps!
