Title:
  Upgrading from Ubuntu 23.10 to 24.04 fails on DisplayLink Module /
  evdi

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  During upgrade using `sudo do-realease-upgrade`

  Upgrade failed and system became unbootable.

  Booting into recovery mode discovered that kernel make fails (linux-
  image-6.8.0-35-generic) for module evdi which is the Dell DisplayLink
  Driver

  
  Solution:
  1) Boot into recovery mode

  2) Follow these instructions to remove module evdi 
  https://askubuntu.com/questions/1467898/dkms-errors-when-updating-upgrading-ubuntu/1468704#1468704

  3) dpkg --configure -a

  4) sudo apt update && sudo apt upgrade

  The system then recovered although the DisplayLink driver was no
  longer present

  As the Dell XPS range are officially covered laptops (not sure if by
  Dell or Ubuntu) I thought this may be useful to resolve

  Further suggestion: removing the evdi module automatically during
  upgrade would at least ensure this issue does not stop the upgrade
  completing. DisplayLink can be reinstalled by those who need it
