I moved aside the file it was complaining about, which I just mentioned,
so I could attach it here. However, by the end of this report, it had
been removed by the package system. I had done this, thinking kit would
keep it safe:
# mv /var/lib/apt/lists/au.archive.ubuntu.com_ubuntu_dists_trusty-
updates_main_i18n_Translation-en /var/lib/apt/lists/aside-
au.archive.ubuntu.com_ubuntu_dists_trusty-updates_main_i18n_Translation-
en
But apparently the package system removes files it doesn't expect to see
there, so I'm sorry, I can't give you the copy I had preserved and
Browsed to (apparently launchpad doesn't up[load the file then, it waits
till you finish filling in the form: bad decision, I guess!
Anyway, for now I've just moved that file aside. That allowed Synaptic
to run ;properly, and now allows Software Updater to start; but after a
while it reports "Failed to download repository information". Ah, and it
has an "Updates|" tab, so probably it's the "Software & Updates" thing
referred to on the URL provided. (It seems user-unfriendly to name it
with the name that you see after you've found it and started it, not the
name you area presented with to start running it in the first place!)
And I suppose you can work out that that page probably refers to
releases other than Trusty, even though you have to read on to discover
that, rather than communicating that up-front, and not mentioning Xenial
or Yakkety at all.
But that said, there is no "Pre-release updates (xenial-proposed)"
option, so I still don't know how I can comply with the request,
unfortunately!
Ah, what the URL *also* doesn't tell you is that you first need to click over
to the Developer Options tab and first select:
Pre-released update (<NAME>-proposed)
Oh. Good thought, but even enabling that didn't make the new option
appear under the Updates tab.
I then tried closing the updater, and it reported the software list was
now out of date and needed reloading. After doing that, I got further
error messages:

Looking under the Authentication tab, all "Trusted software providers" seem
well out of date. Clicking Restore Defaults didn't change any of them, however.
I removed the Google line, and over on the Other Software tab, I also removed
all the lines mentioning Trusty (even though all of them were unchecked, so I
assumed were not being used). I also noticed the Google repository was checked
on the Other Software tab, and after unchecking that and reloading the
repository information, I still got this error:

Oh, okay, although the name displayed under "Other Software" is generic
(like "Recommended updates"), if I actually edit it I see it's referring
to the wrong distribution - Ouch!
This is painful! Now I went through each line under the Other Software
tab, clicked Edit, changed "trusty" to xenial, and close (seems an
absurdly manual process). Afterwards, most of the edit items had
disappeared: i.e. it was as if I'd removed them, not edited them.
After this, I got lost of errors, and had to delete the lines that had
been added to /etc/apt/sources.list by using the GUI - apparently it
doesn't validate its input, and I made errors.
Anyway, I can now check for updates but I get these warnings in the
details area in a message that says "Failed to get package details":

Got rid of the errors. I imagine the warnings are all still there, but
as there are no errors, the warnings have become invisible.
Wow. That was painful.
Incidentally, here are lines 64 and 65 of my /etc/apt/sources.list,
which I believe were added when I clicked the "enable proposed updates"
checkbox in the Software Updater GUI.:
deb http://mirror.optus.net/ubuntu/ xenial-proposed main universe multiverse
deb http://security.ubuntu.com/ubuntu/ xenial-security main universe multiverse
And here are lines 32-37:
