[Bug 1729378] [NEW] impossible to upgrade ubuntu from 17.04 to 17.10

[Michele Giacomelli]

Public bug reported:

after an 'apt dist-upgrade'
and an 'do-release-upgrade' i get this error:


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.


probably my problem is one of the 3 listed but there is no help to solve the problem...

many thanks,
  Michele
