Public bug reported: During the upgrade of the ubuntu version I get an error stating that it cannot calculate the upgrade. I attach what is written in the error screen: Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade. This can be caused by: * Upgrading to a pre-release version of Ubuntu * Running the current pre-release version of Ubuntu * Unofficial software packages not provided by Ubuntu If none of this applies, then please report this bug using the command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.
