I've just rebooted the system and it dropped into a GRUB prompt.
I managed to boot it manually using the instructions here: https://askubuntu.com/questions/38082/how-do-i-manually-boot-from-the-grub-prompt-after-do-release-upgrade
After booting into Xubuntu, I ran:
<pre>sudo grub-install</pre>
Which ran to completion and appears to have succeeded ("Installation finished. No error reported.")
I've just found out that the "shim-signed" package hasn't installed, so I'm waiting for <pre>apt-get install -f</pre> to finish.
