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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1764794 Title: signing: only install a signed kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1764794/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
