Occasional keyboard freeze

At times, 18.10 keyboard stops working. The mouse works fine but nothing we type will appear on the browser or Libre Office. I was told that this bug exists in 18.04. I am not sure whether there is a bug report on it. Can somebody confirm it is a bug. It is making using Ubuntu hard, especially if you type a lot. I really want to see it fixed. Kindly let me how and where I should report this bug. Or if it is already fixed and will get an update in 18.10.

This seems like a basic Support question, so I’ll refer you to the support venues for it.
