OK, now running that new kernel. Well, at least I think it is, but it says:
$ uname -a Linux superstreamer 3.18.0-13-generic #14-Ubuntu SMP Fri Feb 6 09:55:14 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux Made on Feb 6? Can that be right? There was no sign of "3.18.0-13.14~lp1418286v1" in my Grub menu, only 3.18.0-13. Is that good? dmesg now shows 129 times this line Request for unknown module key 'Magrathea: Glacier signing key: bf41f129406f110879b32f34256d25445a48cb14' err -11 ... so that is a sign I do have another kernel. ;-) Snippet from "sudo dpkg -i *deb': "Setting up linux-image-extra-3.18.0-13-generic (3.18.0-13.14~lp1418286v1) ..."
