Title:
  I am unable to upgrade 18.04 to 20.04

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

Bug description:
  It is failed at preparing for upgrade phase.

  Some third party entries in your sources.list were disabled. You can
  re-enable them after the upgrade with the 'software-properties' tool
  or your package manager.


  Invalid package information
  After updating your package information, the essential package 'ubuntu-minimal' could not be located. This may be because you have no official mirrors listed in your software sources, or because of excessive load on the mirror you are using. See /etc/apt/sources.list for the current list of configured software sources.
  In the case of an overloaded mirror, you may want to try the upgrade again later.

  Thanx & regards
  HEl
