[21:05] <malloc> Hi all... I'm trying to build an out of tree kernel module against the linux-image-5.4.0-1058-azure kernel (5.4.0-1058.60~18.04.1) and noticed that linux-*source package linux-hwe-5.4-source-5.4.0 (5.4.0-84.94~18.04.1) is empty.
[21:06] <malloc> According to the source package linux-signed-azure-5.4 the source is in git://git.launchpad.net/~canonical-kernel/ubuntu/+source/linux-signed-azure/+git/bionic within the azure-5.4 branch.
[21:07] <malloc> That repository has the following tag: Ubuntu-hwe-5.4-5.4.0-85.95_18.04.1... what is the easiest way for me to make sure I have the correct sources as the packages move forward?
[21:08] <malloc> the heuristics seem a little fuzzy
[21:13] <sarnold> malloc: my guess is you don't actually want the -source packages but rather the -headers- packages instead
[21:15] <malloc> sarnold: you are right except for one wrinkle for this particular external module that wants to copy a few source files into the local build tree for internal usage
[21:17] <malloc> ddg'ing around lead me to http://ports.ubuntu.com/pool/main/l/linux/linux-source-5.4.0_5.4.0-84.94_all.deb which matches the linux-hwe-5.4-source-5.4.0 version. 
[21:21] <sarnold> malloc: oh, hrm. then you've got something complicated going on
[21:21] <malloc> sarnold: yeah :-/
[21:22] <malloc> i can get by with some chicanery for poc purposes but would like to have a less brittle story to present my team
[21:22] <sarnold> malloc: I don't think the linux source package sources are really involved in building the azure kernels; probably the azure kernel comes from the linux-azure source package http://archive.ubuntu.com/ubuntu/pool/main/l/linux-azure/ -- maybe 'apt source linux-azure-tools' or similar will grab the right thing
[21:23] <sarnold> malloc: (I think the -signed- packages just take binaries from a similarly-named source package, just missing the -signed- piece..)
[21:24] <malloc> sarnold: http://archive.ubuntu.com/ubuntu/pool/main/l/linux-azure/ helps! I see buildpackage sources and the diff.gz for 1058
[21:34] <malloc> sarnold: linux-azure source package is really close... odd how 1058.38 != 1058.60 however  https://vim.cx/?8a25a12faea255c5#2K1BLeQEpMNHmVrmiynbrnrHdKzuZsdcQuFaCs1yKzSc
[21:35] <sarnold> malloc: I think the -meta- packages are mostly just dependencies and the like -- it's only ~10kb of stuff to download, for example
[21:36] <sarnold> malloc: I picked 'linux-azure-tools' as the binary package for 'apt source' on the hopes that it'd pick the linux-azure source package to download
[21:38] <malloc> sarnold: there isn't a corresponding linux-azure-tools-5.4... only linux-azure-tools-5.0.0-1036
[21:38] <malloc> that is my main pickle... getting equiv source for the binary kernel
[21:39] <sarnold> malloc: oh dang. :( that's one downside of looking at the archive directories .. it's hard to know which packages go to which releases :(
[21:47] <malloc> going from the dist files leads to http://archive.ubuntu.com/ubuntu/pool/main/l/linux-azure-5.4/
