Comment 7 for bug 1873288

> The wireguard{,-dkms,-tools} versions do not align: wireguard-dkms is newer. Maybe that's not relevant but I thought I'd mention it.

This part doesn't matter. They're separate packages with separate releases and don't need to align.

However, your mention about the Depends not actually being there is worrying. I thought I had observed the same thing the other day, but Unit193 convinced me I was mistaken, but I don't remember why. I'll wait for him or apw to chime in. I suspect there's an issue here though...

If so, that would mean we need the following to happen:

1. 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/2d36365079f4668660963c5c819db3b544c5d56f and https://salsa.debian.org/debian/wireguard/-/commit/b536ea7e12ee259e5d16e7e66a7b921837223023 )
2. Add Provides: wireguard-modules to the kernel package, just like Debian does ( https://salsa.debian.org/kernel-team/linux/-/commit/5a0532517e072117af71beb281b2cad86e55ba05 )
3. Tweak Debian's semantics for wireguard-dkms to handle the changed build exclusion based on Ubuntu's particulars. (modify https://salsa.debian.org/debian/wireguard-linux-compat/-/blob/debian/master/debian/patches/0002-Avoid-trying-to-compile-on-debian-5.5-kernels-Closes.patch )
