Can someone please explain me the Ubuntu update process? My systems are two kernel updates older now and the bug is still present.
Today, it made the system disk unresponsive on my server, damaging its filesystem and dpkg database in the process. I think that such a bug is critical and should be fixed and pushed to updates immediately. Why is Ubuntu always late with fixing serious bugs which e.g. Debian has fixed a long time ago? I really love Ubuntu but it looks like it is time to move over.
