My greatest praise for Linux is that it's nearly impossible to completely brick the install - it's almost universally possible to recover it, no matter how broken it seems. You can potentially live-boot your XPS from a USB stick, chroot into your existing install and let the upgrade run to completion (Google around for some guides). 18.04 is a very slick OS - I'm running it at work on my company Precision laptop and it's fantastic. The '-d' flag is required until the 18.04.1 release, which is when the new LTS is considered stable enough for existing LTS users to upgrade.

This sounds very useful! I googled but didn't find much - perhaps I did not use the right terms. Can you please post some links that point me in the right direction?

Here:

https://help.ubuntu.com/community/LiveCdRecovery#Update_Fail...

Rather than Ctrl+Alt+F1 (which switches to a TTY), you can open a Terminal instead and run 'sudo -i' to get a root shell.

Replace 'sda1' with your root disk (you may have LVM enabled, and definitely if you have full disk encryption). If you don't have disk encryption, run 'pvscan' and see if it reports anything.

To get the update to finish, you can run 'dpkg --configure --all'.
