Upgrade to release 20.04 from 18.04 failed

[Francisco J. Murillo]

Attempted to upgrade from 18.04 to the newer LTS rel 20.04. Process stopped and a pop-up window indicated that a bug made the upgrade to fail, suggesting to report the bug via "ubuntu-bug ubuntu-release-upghrader-core" as I did, since I couldn't find any clue after checking the suggested logs.

I'll be glad to send you any further information you may need to address the failure.

Many thanks and regards.

Francisco.

Many thanks to everyone for your help.
