Hope I entered these correctly. Looks like I don't have ld-linux.so.3
Try these three:
strings /usr/bin/pihole-FTL | head
dpkg -S ld-linux.so.3
stat /lib/ld-linux.so.3

So the library that pihole-FTL depends on is "/lib64/ld-linux-x86-64.so.2".
Is it installed ?
dpkg -S ld-linux-x86-64.so.2
And is it at the expected location ?
whereis ld-linux-x86-64.so.2
stat /lib64/ld-linux-x86-64.so.2
That library is part of the "libc6" package.
If not installed, you can do so with below one:
sudo apt-get install libc6
And check again if that library is at expected location now with the "whereis" and "stat" commands.

Thank you for the help narrowing this issue down.
Running dpkg, whereis, & stat all resulted in 'no results'. I ran apt-get for the libc6 package and it reported I already had the latest version installed.
I found another command (ldd) that pointed toward a similarly named library ld-linux.so.2 located in /lib/. Could this be what we're looking for?
Dont need to lookup dependencies for the "cat" command.
Its the library "ld-linux-x86-64.so.2", the 64 bits version, what the pi-hole-FTL binary wants.
Could you post results for below ones ?
uname -r -m
dpkg --print-architecture
dpkg --print-foreign-architectures
dpkg -L libc6 | grep ld-linux
sudo find / -name *ld-linux*
apt-cache search ld-linux-x86-64.so.2
EDIT: Mind I altered the find command.
Sorry for the irrelevant tangent. Here are the results of the commands
Missed out an important one:
dpkg --print-architecture
Am not sure if you can run binaries intended for a 64 bit system on a 32 bit (i386) distro but dont think so.
What distro did you install and did you add that foreign architecture "amd64" and what for ?
Dont know if a 32 bit pi-hole-FTL version exists.
If its a fresh install, you could try re-install on the 64 bit version of that distro.
Maybe the @developers can shed some light ?
ok, thanks. Didn't know pi-hole was 64-bit only but more importantly I didn't know I had installed a 32-bit distro. I'll go back and get the right version of Stretch and try this all again.
Will report back the results shortly and confirm if this issue was tied to the wrong architecture.
Am not sure how that 64 bit binary got onto a 32 bit distro but maybe that foreign architecture "amd64" fooled the Pi-hole installer into believing it is a 64 bit system ???
Maybe it suffices to just remove that architecture and try re-install Pi-hole.
You can remove that "amd64" architecture with:
sudo dpkg --remove-architecture amd64
Or add it again with:
sudo dpkg --add-architecture amd64
I didnt say that and @Mcat12 just confirmed that a 32 bit version exists also.
Forget removing or adding amd64 architecture, it seems the installer decides on what system architecture is detected and doesnt look at distro architecture.
From the install script:
# Store architecture in a variable
machine=$(uname -m)
.
.
elif [[ "${machine}" == "x86_64" ]]; then
# 64bit
echo -e "${OVER} ${TICK} Detected x86_64 architecture"
# set the binary to be used
binary="pihole-FTL-linux-x86_64"
So the only fix left is try install the 64 bit distro version ... I think 
The installer script messes things up on my system (32bit). The script assumes a lot, while it simply should ask the user what they want. It currently blindly overwrites pihole-FTL with the wrong version.
I strongly disagree. Many users use Pi-hole as their first Raspberry Pi, sometimes even as their first Linux experiment. Even if we'd ask them which architecture they are running on, that might already be too much. The Pi-hole installer is constructed to make the installation as simple and straightforward as possible.
Please be more specific. Does that mean you are running a 32bit on 64bit capable hardware? If so, why? If not, what is the problem you are seeing?

I agree that it may be a bit of a stretch to cover it in the installer.
My setup is not really ordinary I guess:
Architecture: x86_64
CPU op-mode(s): 32-bit, 64-bit
I run Pi-hole on Xpenology in the Chroot environment, somehow some libraries are 32 bit forcing me to use the 32 bit FTL version.
Are you using a 64bit kernel? Maybe you can just install the missing 64bit ldd.
@llloydxmas & @bakman2 ,
FYI, we found solution to run the 64 bits pihole-FTL binary on a 32 bits distro if your running a 64 bits kernel:
Important bit is that "dpkg --print-foreign-architectures" is set for "amd64" and the repo in the "sources.list" file includes the "amd64" packages.
