Comment 0 for bug 1830379

On Ubuntu 18.04, with `apt-get source <packagename>` being the de facto way of getting (src-deb) sources for a binary package, it is not so with the linux kernel.

`apt-get source linux-image-$(uname -r)` -- leads to "linux-signed" which is not the kernel src deb
`apt-get source linux-image-generic` -- leads to "linux-meta" which is, again, not it
`apt-get source linux` -- obtains the correct src deb but that's not transparent or obvious to new users and a deviation from the usual standard of using `apt-get source`.
