can not do: do-release-upgrade

[robert rottermann]

Hi there

I would like to do a do-release-upgrade, but when I try the process asks to do 
all upgrades first, and when I try to do it I get the following dialog/messages.

What can I do?

thanks

Robert

2 packages can be updated.
2 updates are security updates.

New release '20.04.1 LTS' available.
Run 'do-release-upgrade' to upgrade to it.
