Where should people give feedback on Ubuntu?

As of 2020, the best place to give general feedback is in https://discourse.ubuntu.com/.

It all depends what kind of bugs you found.

Here are a few possible problems you can run into and these are the packages against which you can open a bug

• Dash, Panel, HUD, Expo, Launcher issues --- unity, compiz
• Kernel specific thing -- Linux
• If you get errrors when running application, then you should log bugs against glib if the error messages show something like glib, gio, peas. The bug triagers will assign them to correct ones

If you want to discuss something related to desktop related functionality like System Settings, Applications inclusion etc, then send a mail to [email protected]

If you want to help out in QA related regression testing, then as you mentioned [email protected] is the best place.

I would recommend against spending time on brainstorm. There are better ways to provide user feedback.

If your question is related to foundations of ubuntu like udisk, glib etc, then it is better to post it on [email protected]
