I gave 5.3.0-23.25~18.04.2 on the canonical kernel team ppa a try, but it looks like the signing issue still persists.

This results in no modules being signed in hwe kernels based on 5.3, rendering systems with secure boot enabled unbootable. Fix: Check for the module signature at the end of modules instead of relying on modinfo. This can be done without any external tools needing to be aware of module signatures. Test Case: Check that all built modules contain signatures, except for those in staging which have not been whitelisted. Regression Potential: I can think of two possible regression situations. We could regress to the behavior prior to the fix for bug 1850234, or the eoan 5.3 kernel could also end up with all modules unsigned. I've done test builds of both the eoan 5.3 kernel and the bionic 5.3 hwe-edge kernel with this patch and checked that the results are as intended. We should also check this again once new kernels have been built, before copying them out to -proposed. --- The latest hwe-edge kernel 5.3.0-23.25 fails to boot with the message that it cannot find the UUID associated with the root partition. The user gets dropped to a busybox shell with an initramfs prompt. The standard hwe kernel does not have this issue and the last hwe-edge kernel that does work is 5.3.0-19.20.
