Howdy!  I'm the author of the motd-news code, as well as the story in
the subject of this bug.

Note that motd.ubuntu.com has been updated to say:

" * Ubuntu 16.10 will reach end of life on Wednesday, July 20th"

It may be useful to explain a bit of the design of motd-news.  Note that
much of this was copied over from my comment on the Hacker News thread:
https://news.ycombinator.com/edit?id=14663947

By design:

- Asynchronously, about 60 seconds after boot, a systemd timer fires
which runs "/etc/update-motd.d/50-motd-news --force"

- It sources 3 admin-editable config variables in /etc/default/motd-
news.  The defaults are: ENABLED=1, URLS="https://motd.ubuntu.com";,
WAIT="5"

- The admin can disable it entirely (ENABLED=0), change or add other
MOTD news sources (your corporate IT team could run its own), and change
the wait time in seconds

- If it's enabled, that systemd timer job will loop over each of the
URLS (note, that it's important that these should be https with valid
SSL certificates), trim them to 80 characters per line, and a maximum of
10 lines, and concatenate them to a cache file in /var/cache/motd-news

- Every ~12 hours thereafter (with a little bit of random timer
fuzzing), this systemd timer job will re-run and update the /var/cache
/motd-news

- Upon login, the contents of /var/cache/motd-news is just printed to
screen.  There was a bug (fixed now, working its way through the Ubuntu
update process), in that an empty cache file was not getting, if the
fetch failed, so the fetch was retried every time (and failed every
time, with the $WAIT delay of 5 seconds).  Obviously, it was a simple
fix.

As I am generally responsible for this feature in Ubuntu (as the Ubuntu
Product Manager for the design, and the Ubuntu Core Developer for the
implementation) I'll also respond to the discussion about this feature
being included in Ubuntu at all...

- Back in 2009, Ubuntu was the first distribution to add the concept of
a "dynamic MOTD", by introducing the /etc/update-motd.d/* structure of
scripts.  I originally implemented it for Landscape (a commercial
package management system by Canonical), but it has since also been
adopted by Debian, Amazon Linux, and others.

- It's a flexible framework that enables distro packages or
administrators to add executable scripts in /etc/update-motd.d/* to
generate informative, interesting messages displayed at login.

- This was quite interesting, in that for almost 40 years of Linux/UNIX,
the "Message of the Day" was anything but that...  It was a message that
was created at one point in time, when the distro released, and that's
about it.  And we managed to change that.

- If you look in your Ubuntu's /etc/update-motd.d/, you'll see a set of
scripts.  One prints the generic "welcome" banner.  The next one prints
3 links, as to where to find help.  You'll also find one that counts and
displays the number of package updates available for the local system.
Another tells you if a reboot is required.

- All of these are locally generated, based on local information
available on the system.

- In Ubuntu 17.04, we added /etc/update-motd.d/50-motd-news.  This is
the script who's design is described above.  The motivation is
threefold:

* Sometimes, there's critical information that either we, the distro, or
perhaps even the local IT administrator of a fleet of systems needs to
communicate to users at login.  Think, "ShellShock", "Heartbleed",
"StackClash".  This seems to happen every few months, in the current
state of the world.

* Other times, we need to communicate something about the distribution.
EoL messages, new feature availability, etc.

* And sometimes, it's just a matter of presenting a fun fact.  News from
the world of Ubuntu.  Or even your own IT department.  Such was the case
with the Silicon Valley / HBO message.  It was just an interesting
tidbit of potpourri from the world of Ubuntu.  Last week's message
actually announced an Ubuntu conference in Latin America.  The week
before, we linked to an article asking for feedback on Kubuntu.  Before
that, we announced the availability of Extended Security Maintenance
updates for 12.04.  And so on.

- There is a team of engineering managers at Canonical (the ~ubuntu-motd
team in Launchpad), all of who have shared write access to the source
code repository (lp:ubuntu-motd in Launchpad).  Going forward, we're
going to review one another's proposed message merges.  In fact, that's
an open source repository.  You're welcome to propose your own messages
for merging, if you have a well formatted, informative message for
Ubuntu users.  We'll be happy to review and include them in the future.

As always, I'm impressed with the critical analysis of the Ubuntu
community.  We, the Ubuntu ecosystem, are held by the Ubuntu community
to a very high standard, and we're quite humbled by that.  Thank you for
the continued feedback and response.

Cheers,
Dustin
