started with xenial install. grub2 is at 2.02~beta2-36ubuntu3.28 put apparmor profile in place, and upgrading non-interactively
upgrade to 2.02-2ubuntu8.19 fails as expected with grub-install saying that error cannot open /dev/vda permission denied.
grub-pc package remains in iF state.
in /boot/grub everything is unchanged, but fonts/unicode.pf2 which should be relatively harmless.
reboot works with still old 3.28 in the grub-menu title
installing with invalid device (sda, whereas vda is in use) failed
new devices got offered to install grub onto
calling dpkg-reconfigure also installed grub onto the selected device
git status in /boot/grub confirms that all modules got updated, since new bootloader was installed onto the block device successfully.
reboot worked with the 2.02 (newstyle) menu header.
all is good.
