thank you for reporting this. I've tried to reproduce this on an am64 Wily server upgrade to Xenial upgrade but I can't reproduce this. To debug this further I require some extra information:
1. How did you perform the upgrade to Xenial? 2. Can you provide a list of all the packages installed on your system: dpkg --get-selections > installed.log and attached the installed.log to the bug report.
