Testing this required updating several packages from xenial-proposed In order to install them all I ran this:
sudo apt install -t=xenial-proposed linux-signed-generic linux-generic (which is something that is not told in the previous document) In its execution an error occurred; here is an extraction of the part of the output: /etc/kernel/header_postinst.d/dkms: Error!

If I would use open source driver nouveu, instead, I could test this, but I would not be able to use HDMI IIRC. Well, I'll try. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1764794 Title: signing: only install a signed kernel Status in linux package in Ubuntu: Fix Released Status in linux source package in Trusty: Fix Committed Status in linux source package in Xenial: Fix Committed Bug description: We should switch the default kernel install to the signed kernel. This makes it much harder to uninstall the signed kernel in environments which enforce the kernel to be signed. Boot loaders which can understand and validate it want the signed image, those which do not should ignore the appended signature.
