Comment 4 for bug 1775939

Currently there are over 29000 source packages in the Ubuntu archives for just bionic, most of which are in universe. It is *impossible* to timely manage all of those packages with the resources we have, which is why 'main' packages are the ones that we try to maintain for the most part. rkhunter is a package in *universe* so the MOTU team should be mainly responsible for taking care of its updates. Similarly, the SRU team also cannot always handle every incoming request instantly - we're doing what we can but there's just a lot of work in all packages of all components.
Remember it is not just 'Canonical'. Ubuntu is more than just 'Canonical'.
