Hello, Thank you for filing this bug and making Ubuntu server better.
However, this smells odd because: 3.9.1-4ubuntu3 -> this version is in trust (and 3.9.1-4ubuntu3.14.04.1 is in trust-updates). Then xenial has 3.9.1-4.2ubuntu1 and bionic has 3.10.2-1. This package was then dropped and isn't available in focal (20.04) at all. I am not sure how you're trying to install this package but if you try to install packages from different releases, I'd expect things to not work. I am marking this bug as "Invalid" for now but should you feel otherwise or think it's actually a problem in Focal, please change the status to "New" again with a comment explaining why you think it's a bug. Hope this helps.
