Migrating From Ubuntu PPA to Real Ubuntu Packages

[Jason A. Donenfeld]

Looks like we're all set for these kernels:

zx2c4 at bionicman:~$ apt-cache show linux-image-* | grep -C5 "^Source: linux-meta" | grep -B10 "^Provides: .*wireguard-modules" | grep ^Package:
Package: linux-image-generic

But we are not all set for these kernels:

Appears that the "oem" kernel is part of the bad list.

I'll note that this is at least the third time Canonical has forgotten
the "Provides:" line for kernel packages. I'd highly recommend they
put some time into double checking their procedures.
