[Bug 1577069] [NEW] upgrade from 14.04 LTS failed

[Clinton Bridge]

Public bug reported:

I set the Notify me of a new Ubuntu version to any new version, run the upgrade tool and was expecting to be prompted to upgrade to 16.04. Instead i was prompted to upgrade to version 15.
When i run the tool it failed indicating that one of my upgrade package files had been modified??
Sorry i can't be of anymore help than this.
I'm running 14.04 LTS
