Title:
  Ubiquity installation hangs & fails due to nvidea-uvm probe error

Status in ubiquity package in Ubuntu:
  Confirmed

Bug description:
  Installation of Ubuntu 19.04 (disco-desktop-amd64.iso, daily build
  2019-02-03 10:50) hangs and ultimately fails (i.e. the installation
  does not progress beyond this point), between the Disk Setup and the
  Timezone step. This happens regardless of whether having clicked to
  install straight away, or from a live desktop session.

  From a live desktop session, the journal shows the following error
  (datetime obviously changes) which loops continuously for the duration
  of the installation 'hang' (this message can also be seen via dmesg):

  Feb 15 22:18:20 kubuntu kernel: NVRM: The NVIDIA probe routine was not called for 1 device(s).
  Feb 15 22:18:20 kubuntu kernel: NVRM: This can occur when a driver such as:
                                  NVRM: nouveau, rivafb, nvidiafb or rivatv

                                  NVRM: driver(s)), then try loading the NVIDIA kernel module
                                  NVRM: again.
