Several months ago I reported this bug:
https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe-5.8/+bug/1931787
(Also documented here on Ask Ubuntu).
I noticed many other bug reports were of a similar nature - software configuration bugs in hardware interfaces. So I marked them as duplicates, and my post got heaps of heat! But there has been zero action for months. Can anybody explain why? Is Launchpad short of staffing/bug fixers? Is it monitored by Canonical? (I wish I had the skills to contribute, but alas I am totally amateur).
