Ubuntu 18.04.5 released August 13th with kernel 5.4.0-42-generic. However, there is no linux-source-5.4.0 package for Ubuntu 18.
Under bionic and bionic-updates, there is no linux-source-5.4.0: https://packages.ubuntu.com/search?suite=all&searchon=names&keywords=linux-source
This seems like a mistake to me. There are linux-source packages available for kernel releases up to 5.3.0.
Please make linux-source-5.4.0 available on Ubuntu 18 repositories.
Apologies if this is a duplicate of the below. I was not sure where to file.
