Thanks for your Help Brian; you saved my day !
I managed to upgrade to 20.04 today.
After removing all the node package I could find in Synaptic package manager.

As an improvement, it could be nice to clarify the end user explanation for the failure to upgrade.
If I had basically your previous recommandation in-app this would have helped.
Instead I have been facing a generic error message :

A lot of developper in node need the latest version of node , as it is evolving so fast .

Anyhow thanks a lot for your support

  Cannot upgrade Ubuntu mate 18.04 to 20.04

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

Bug description:
  This is a similar bug as Bug #1887544 which I have been following for 6 month but is now closed.
  "upgrade from 18.04 to 20.04 fails to calculate if python-dbg is installed".

  @Brian Murray (brian-murray) suggested :
  "Could you please open a new bug report using "ubuntu-bug ubuntu-release-upgrader"? Once you've done that let me know and I'll have a look at the logs."

  I could do this update on two other Unbuntu mate 18.04 machines (that
  I use less. ie fewer softwares).

  You should have the logs attached. Let me know if you need me to do extra actions.
  I have tried 10 times to upgrade the past motnhes.
