Taking a look at this and noticed that the second commit wipes out the change from the first commit which adds the azure headers.

Also I'm looking into the --disable-strict-errors flag but unless I'm mistaken it's not ported into 2.15. seems like we would need to cherry-pick 7f1aa5b into the branch to get it. I'll need to test this to understand more around that.

What testing was done on this branch?

Jeff Bearer (@jeffbearer) there is no need to add azure headers specifically - due to the fact that packages like linux-headers-generic, linux-headers-azure and linux-headers-azure-nvidia actually all provide linux-headers. Using the most general linux-headers as the dependency is a sane and upstreamable choice.
I will check if removing disable-strict-errors works.
