All, thank you for the replies yesterday.  Would you be able to offer
some more insight into updating the 2 packages?  I have had some
successes, but not all the beagle bones have
recognized the new version of batman-adv when I run batctl -v.

The general method I've been using is the script here
https://gist.github.com/marvin/186a609d1e88f7426747 with version 2016.4.
The starting version on the Beagle Bones is batctl debian-2012.1.0-1 >
[batman-adv 2012.5.0] as mentioned previously.
After running this script and doing a
$ modprobe batman-adv
followed by
$ batctl -v
I get $ batctl 2016.4 [batman-adv 2012.5.0].

I have also attempted to uninstall batctl and batman-adv with
$ apt-get --purge remove batctl
 and
$ apt-get --purge remove batman-adv
and reinstall using the script, but that hasn't worked across all devices.

The laptop I have is running Debian 9.5 with batctl debian-2016.5-1
[batman-adv 2016.4] and the Beagles are running Debian 7.9.  I would
like to avoid reimaging the Beagles at this point in time.
Please pardon my lack of knowledge on the topic, as I'm still
relatively new to Linux and have been learning a great deal in the
past few months.
I greatly appreciate your help on the topic.

Regards,
Corey

Could you get even higher than 2016.4, like 2018.x? Or is your kernel too old?

That looks like you still have the old kernel module loaded, or the new one 
not installed properly.

Not sure if that is right, as batman-adv (at least nowadays) comes as part of 
the Linux kernel, and not as a Debian package. You can install/deinstall 
batctl using apt-get though.

You can check the selected kernel module using modinfo. Like that:

# modinfo batman-adv
filename:       /lib/modules/4.17.0-0.bpo.3-amd64/kernel/net/batman-adv/
batman-adv.ko
alias:          net-pf-16-proto-16-family-batadv
alias:          rtnl-link-batadv
version:        2018.1

depends:        libcrc32c,bridge,crc16
retpoline:      Y
intree:         Y
name:           batman_adv
vermagic:       4.17.0-0.bpo.3-amd64 SMP mod_unload modversions 

Here you can also see the position where the kernel module is loaded from. 
This should show 2016.4 (or whatever version you wanted to install), if it 
doesn't, something went wrong in your installation.

Cheers,
      Simon

Why did you start a new thread and why did you use such a non-specific 
subject?

The script mentions 2014.3.0. Anyway, both versions have known problems. See 
https://git.open-mesh.org/batman-adv.git/blob/HEAD:/CHANGELOG.rst

Ok, I have no idea why it failed. Maybe because it wasn't successful? Or 
because there was a problem? Or was there maybe an error? ;)

A little bit more serious: Any info what failed? Any build errors? What does 
modinfo batman-adv say? Are there multiple batman-adv.ko in your 
/lib/modules/... and the wrong one was loaded by modprobe? Does `depmod -a` 
help (generates the module.dep again)?

I don't want to crush your hopes but if you use broken components then you 
will most likely end up with a broken finished product. And as I said earlier, 
there are numerous known problems in the batman-adv versions which you've 
mentioned earlier.

Kind regards,
