I'm using a Raspberry Pi Zero W with Raspbian Stretch. When I do sudo apt-get update while logged in through a Bluetooth serial console, I get those exact same Waited for apt-key but it wasn't there error messages. This was driving me nuts until I found your post above.
Running it under strace works fine for me, just like you. But running apt-get under ...

try
python2.7 easencode.py -z $(multimon-ng) output.wav
if you are in bash.
$( ) construct will execute command and insert result (stripped of end of line) in current command.

Exim has a compile-time setting FIXED_NEVER_USERS which disallows delivering to root: https://github.com/Exim/exim/wiki/Q0039#question. There is no way around this without building your own debian package.

the commands you posted will be executed one by one, not in parallel, so halt will execute only after sync completed.
if you added & to sync, so
sync &
halt - f
sync would work in background and coukd not finish in time, as halt would run at the same time.
summing up, you're safe with sync executing in full before halt is invoked.
NOTE:
It's ...

Simply selecting rng-tools (under Target Packages -> Hardware Handling in the Buildroot menuconfig) and running make completely fixed the problem. Buildroot automatically added a S21rngd in /etc/init.d/. My system now starts up in about 4 seconds with no input devices attached.

We can convert the usbArray to a suitable escaped string using printf:
printf ' \\x%s' "${usbArray[@]}"
This produces \x5A\x00\x00\x0d\x0a\x71.
Then pass that as argument to another printf, to interpret those as escape codes:
printf '%b\n' "$(printf '\\x%s' "${usbArray[@]}")"
To demonstrate that we have the correct output, inspect it using od:
$ printf ...

Why: This error is being caused by a combination of things:
1) The command th-cmd --socket /var/run/thd.socket --passfd --udev produces a segfault. This seems to be because triggerhappy hasn't been patched to address a number of issues reported over the last 4 years...

Perhaps this question should be on Stackoverflow, since it's really about how to follow instructions, albeit linux commands and the utility is designed to run on Linux, but not really a Linux question per se, apart from the understanding of what it does.
The instructions are outlined :
Set your noip.com account info and number of hosts in noip-renew....

Add this to your install script:
sudo mkdir /opt/xauthorityfix
sudo chmod 777 /opt/xauthorityfix
echo "#!/bin/sh" > /opt/xauthorityfix/setxauthority.sh
echo "export XAUTHORITY=$XAUTHORITY" >> /opt/xauthorityfix/setxauthority.sh
sudo chmod 755 /opt/xauthorityfix
After that, wrap your python script in this shell script:
#!/bin/sh
source /opt/...
