While installing security updates in a seldomly used virtual machine, the latest kernel package was ready to be configured when I got the following error:

First I didn't quite get the line about "Couldn't find PV pv1. Check your device.map", but after some time it dawned on me that "PV" might mean "physical volume", a term used by LVM. I also remembered that I extended the LVM volume group with an additional block device that I attached to the virtual machine.
