[Bug 1892599] Re: Attempt to upgrade from Ubuntu 18.10 (cosmic)

It's nice to have work-around.
However, do-release-upgrade is expected to work, even if that system was offline for some long period of time.

Title:
  Attempt to upgrade from Ubuntu 18.10 (cosmic)

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

Bug description:
  This computer was turned off for about half year or more.
  From that time on I can't do a normal upgrade to next Ubuntu.

  Since I could not install anything and I have had a work to do, I did a manual upgrade of
    /etc/apt/sources.list
  to point on "eoan" instead of "cosmic".
  That helped to install some programs.

  However, do-release-upgrade is still failing.
  Tried a workaround in
     https://nelsonslog.wordpress.com/2020/02/21/upgrading-from-an-unsupported-ubuntu/
  It still crashes.
