Title:
  Unable to run do-release-upgrade under script(1) because of a need to
  clear the screen

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

Bug description:
  I like to do system updates under script(1) and have a collection of
  bash aliases to do these things and log the script output.  Otherwise
  all that stuff scrolls by with no chance for me to use it later.

  I just tried to update my system to 18.04, and it failed with the following output:
    Checking for a new Ubuntu release

    authenticate 'bionic.tar.gz' against 'bionic.tar.gz.gpg' 
    extracting 'bionic.tar.gz'
    Clear screen capability required.

  This seems onerous to me.  What's the point of generating output if
  there's no way to learn from it, refer to it, or remember it?
