The root file system is on encrypted LVM, created by the "Guided - use entire disk and set up encrypted LVM" choice in the "Disk Setup" step of the Kubuntu 16.04.3 installer. I wasn'a able to activate the volume group. Regardless of what I tried - vgchange -a y, vgchange, lvs, vgs, vgdisplay, pvs, pvdisplay - all the commands finished with no output.

Silly me! I've just forgotten to unlock the crypto partition first. %-(  I _can_ access the root file system from my USB stick, which doesn't use LVM, and thus doesn't yield a conflict of the volume group names.
