Francesco, thank you for reporting this and helping make Ubuntu better. The supported way of upgrading may be found at http://www.ubuntu.com/download/desktop/upgrade . Could you please advise how precisely you are upgrading in a keyboard click-for-click fashion?

A screenshot of the error message you are encountering would be helpful.

Found this while googling for the same issue. Will continue researching and update here if I find anything.

Here is the output I get:

Cannot upgrade

An upgrade from 'trusty' to 'vivid' is not supported with this tool.

Here's the log from yesterday

[Aaron (apelly)]

Today it appears to be working.

[Aaron (apelly)]

attached log from an upgrade that looks like it might have worked. I aborted it though.

what changed in between? to the best of my recollection, one suspend, and an apt-get upgrade, there was a new kernel in there I think and I have not rebooted yet.

Aaron, doing an upgrade as you attempted is not supported. You would need to follow the instructions as previously advised in https://bugs.launchpad.net/ubuntu/+bug/1502800/comments/3 .

[Aaron (apelly)]

That can not be the case.

Nevertheless, my problem has gone away, and you have removed my logs. I will go away too.
