Comment 32 for bug 1686183

Zesty verification with ubuntu-advantage-tools 2 from zesty-proposed:
 *** 2 500
        500 http://br.archive.ubuntu.com/ubuntu zesty-proposed/main amd64 Packages

a) Since there is no ESM for zesty, the enable-esm command fails with a 404 Not found error:
$ sudo ubuntu-advantage enable-esm <redacteD>
Running apt-get update...
W: The repository 'https://esm.ubuntu.com/ubuntu zesty Release' does not have a Release file.
E: Failed to fetch https://esm.ubuntu.com/ubuntu/dists/zesty/main/binary-amd64/Packages 404 Not Found
E: Some index files failed to download. They have been ignored, or old ones used instead.

apt-get update will remain in this state until esm is disabled. This will probably affect the "package update count" message that is displayed in the MOTD (unrelated to ubuntu-advantage or ESM), since apt-get update is erroring.

b) No ubuntu-advantage related messages are shown in MOTD, regardless if esm is enabled or not, which is correct for non-precise releases of Ubuntu.
