Automatic upgrade from 19.10 to 20.04 fails

[Hasimir]

Hi,

I'm running Ubuntu 19.10 and today the system notified me that the OS could be upgraded to 20.04.
But when I click YES the software upgrade window closes and ... nothing.
Nothing happens.
I tried to start the process from command line, but it just says the software is up to date.

How can I fix this?

The command
do-release-upgrade -d

return the following error:
Upgrades to the development release are only available from the latest supported release.

lsb_release -a tells me that:
No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 19.10
Release: 19.10
Codename: eoan

There are only minor differences between 19.10 and 20.04 so if 19.10 is working fine you could keep it until july.

Anyway, if you want 20.04 then a clean install is a safer approach than trying to upgrade.
