Public bug reported:
With the changes to update-manager in bug 1497024 it should be possible
to upgrade from Ubuntu 16.04 to 17.04 (provided 16.10 is End of Life).
While update-manager will download the zesty.tar.gz file it will not run
and will instead say "An upgrade from 'X' to 'Z' is not supported with
this tool." This is because ubuntu-release-upgrader has not been
configured to upgrade from 16.04 to 17.04.
[Test Case]
1) Run do-release-upgrade (notice it download yakkety.tar.gz)
2) Set yakkety to unsupported in ~/.cache/update-manager-core/meta-release
3) Run do-release-upgrade again (notice it download zesty.tar.gz)
With the dist-upgrader tarball currently available you'll receive an
error message about the upgrade path being unsupported. With the version
of the dist-upgrader tarball in proposed (accessible by running do-
release-upgrade -p and modifying meta-release-proposed in the cache
folder) you will not receive that error message.
[Regression Potential]
It's possible the upgrade won't work for people, but I'll be watching out for
issues and its better than we resolve upgrade issues now rather then when
people are upgrading from LTS to LTS.
