Status changed to 'Confirmed' because the bug affects multiple users.

[Brian Murray (brian-murray)]

Yes, this is due to running out of space in /boot.

How many kernels do you have installed? Are they all using xz compression?

[Stuart Bishop (stub)]

I have the default number of kernels installed with unattended upgrades & autoremove, so 3. I have configured xz compression, which normally stops this. /boot is undersized due to this install being done with a Xenial pre-release (before the default /boot size was increased). I don't know what changed that had apport flag this as a new bug.
