Title:
  nvidia-340 package post-installation script subprocess returned error
  exit status 10

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

Bug description:
  I love Ubuntu!!
  I had the following error code while upgrading from ubuntu 18.04 to 20.04 :
  '''sh
  installed nvidia-340 package post-installation script subprocess returned error exit status 10
  '''
  This followed by the upgrade getting aborted. From now onwards the screen is blank whenever it is restarted.
  Then I had to follow this article

  https://koen.vervloesem.eu/blog/fixing-a-failed-upgrade-to-ubuntu-2004
  -lts-in-recovery-mode/

  and this article helped me to get back the desktop GUI view. 
  However I would like to know why it was caused. Was it due to hardware problems or the incomplete installation of any drivers, I am not sure of it. I am reporting this as a bug because I was told to do so by the do-release-upgrade software. Please let me know if you need any logs.
