I guess the bug # is wrong here, bug 576923 deals with wresp (i.e.,
completely outside of Ubuntu).

This is a good question. It is probable that u-m should start by
updating the repositories for the current release, and then verifying
some values (which ones, exactly, I am not sure), and offering to first
do a full current update, and *then* offering a version upgrade.

So... I would open a bug on u-m asking for more consistency checks
before doing an Ubuntu version upgrade.

Would you mind opening this as a bug?

Thank you.
