** Description changed:

  Steps to reproduce:
  1. Have fully upgraded Ubuntu MATE 18.04.5 LTS installed
  2. Open terminal and execute
  
  ```
  sudo do-release-upgrade
  ```
  
  Expected results:
  * upgrade process started
  
  Actual results:
  * upgrade process does not start:
  
  ```
- $ sudo do-release-upgrade 
+ $ sudo do-release-upgrade
  Checking for a new Ubuntu release
  There is no development version of an LTS available.
- To upgrade to the latest non-LTS develoment release 
+ To upgrade to the latest non-LTS develoment release
  set Prompt=normal in /etc/update-manager/release-upgrades.
  ```
  
  Note: this is not expected as per
  https://wiki.ubuntu.com/FocalFossa/ReleaseNotes
  
  > The -d switch is necessary to upgrade from Ubuntu 18.04 LTS as
  upgrades have not yet been enabled and will only be enabled after the
  first point release of 20.04 LTS
  
  The problem is caused by the fact that http://changelogs.ubuntu.com
  /meta-release-lts is out of date. It does not mention 20.04 LTS (Focal
  Fossa).
+ 
+ Workaround: setting Prompt=normal in /etc/update-manager/release-
+ upgrades and re-running the do-release-upgrade command starts the
+ upgrade process.
