nfs mirror not handled correctly?

[Seth Arnold]

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if the mirror information is out of date.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.

You may want to run apt-get update to correct these problems

I'm surprised about the "no mirror information" mention. Here's what it looks like while the tool is waiting patiently for me to return:

$ head /etc/apt/sources.list

(The sources.list previously said 'trusty', since it is running trusty.. but the information to see that xenial is there, and alive, is surely visible.)

Thanks

(Is it usual for e.g. trusty machines to already have xenial lines in their apt sources? Is that what this language is expecting?)

Thanks
