I don't know if that will help with the piracy usage though.
I forgot about OpenDNS until after I sent the email. I configured the modem
to hand out the OpenDNS ip addrs via DHCP. I tested it. It with a few sites
and it blocked those, but the real test will be when people start using it
as one cannon imagine all the dark & creepy corners of the Internet that
people like to explore.
The biggest problem with freee OpenDNS is that when a web site is blocked
throws up a generic Microsoft tech support page instead of something more
useful like"access to this site has been blocked because the content
violates our service usage policy."

Do not attempt to perform a release upgrade while your repository is in a
broken state.
In fact, do not attempt to perform any sort of installation or upgrade
until you resolve the error with Google Earth. You will break your system
to the point where the only solution is to reinstall from scratch.
I've seen this error countless times since 8.04. This error literally
predates Mint and end users have a tendency to break their installs over
some bad error reporting. Resolve the error for apt-get update before
attempting any further steps.

I've never done an upgrade, only updates. Most of the time, and all of
the time in the past five or more years, I've always had another machine
on which to try out the newer version. I'm in that state now with 18.04.
I did an install of Ubuntu MATE 18.04 on my other desktop machine and
ran into problems. Someone pointed out that waiting for 18.04.1 was
safer, so I'm doing that. Meanwhile I still get notices to update 16.04.
So I'll go through the other recommended steps after work this
afternoon, and see how that goes.
Thanks for the warning.

Everyone tells me to do a clean install instead of a dist-upgrade. That
probably works well for them because the stock install has almost
everything they need. For me a fresh install is a pain. The last time I
did it I spent a week getting everything installed and configured. I'm
not exaggerating - a full week of long days.
I recently did a dist-upgrade of the computer I'm writing this on from
14.04 to 16.04. Lots of things were messed up, but it took me only a
couple days to get things back in order. And Ubuntu deliberately does
not list a new LTS as available in the Update Manager until the first
dot release.
But regarding things getting messed up, why in the hell did the
dist-upgrade decide to uninstall all my KDE apps? And after the
dist-upgrade I found that I could not reinstall any of the KDE apps (or
anything else) because I had broken packages. Synaptic said it fixed the
broken packages, but it did not. I tried sudo apt-get update, but that
failed also ('can't update because you have held packages.').
Eventually I got relief using aptitude at the command line.
I used to be a fan of Debian package management because it seemed more
foolproof than RPM. Lately I'm having second thoughts.

I went through the process I followed earlier, trying to fix the no
public key issue. That seems to have worked, but it brought up a
different one:
N: Skipping acquire of configured file 'main/binary-i386/Packages' as
repository 'http://dl.google.com/linux/earth/deb stable InRelease'
doesn't support architecture 'i386'
I searched for that error message and found out that it's a known
problem, with a solution that has to be done regularly because the fix
is to a file that is automatically generated, and the fix is
overwritten. One solution is a cron job that "fixes" the file every day
or something. But another would be to skip getting a Google Earth update
for now. But, I don't find a place to do that in Software Updater.
In Synaptic, Software & Updates, Other Software, I unchecked
http://dl.google.com/linux/earth/deb/ stable main
I reran sudo apt-get update --fix-missing, and the error message was not
there. So I reran Software Updater, and it finished successfully.
I'm expecting to move over to 18.04 before too long, so I'm not all that
concerned about a non-updated version of Google Earth, which I only use
occasionally.
Thanks to all for the various pointers, which when combined, solved my
problem.

I'm doing some volunteer IT work for a small, local non-profit that has a
few Free Geek Linux Mint computers connected to a Zyxel modem w. 10 mb/s
CenturyLink internet connection.
In the past they've had the typical problems of inappropriate content and
piracy and have received the cease & desist letters from CenturyLink.
The Zyxel modem doesn't have much in the way of features & functionality
for content filtering and service or web site blocking.
I have some basic knowledge/experience with proxy servers like BlueCoat and
DD-WRT. I'm looking for suggestions on the best used devices that I can
find at Free Geek or Goodwill and Open Source firmware that's not overly
complicated to setup and maintain.
Also, any suggestions for low resource anti-malware of content filtering
software I can run on the Ubuntu Mint PCs. I've used ClamAV before but I
never know if I have it setup correctly or if it's actually any good.
Thank you,
Mike
