Public bug reported: The do-release-upgrade -d from trusty to xenial looked funny on my laptop with a local mirror mounted over nfs:
Reading state information... Done Building data structures... Done Updating repository information No valid mirror found While scanning your repository information no mirror entry for the upgrade was found. This can happen if you run an internal mirror or if the mirror information is out of date. Do you want to rewrite your 'sources.list' file anyway? If you choose 'Yes' here it will update all 'trusty' to 'xenial' entries. If you select 'No' the upgrade will cancel.
