Comment 9 for bug 1873288

I've let people know in #ubuntu-kernel, so hopefully Canonical will take a look. To recap for whoever inherits this bug, the following things need to be done:

1. Add back the "Provides: wireguard-modules" in linux-image-generic. This is really important. It used to be there but has strangely been dropped, which is why this bug report was filed by a user.

2.. Reverse the order of wireguard-modules and wireguard-dkms in both the Depends: and Recommends:. Importing the latest Debian package will do this:

https://salsa.debian.org/debian/wireguard/-/commit/b536ea7e12ee259e5d16e7e66a7b921837223023

3. Optional: tweak Debian's semantics for wireguard-dkms to handle the changed build exclusion based on Ubuntu's particulars. That involves modifying:
