Installation on Odroid-U3 possible?

General

I have an Odroid-U3 in the drawer and would like to put it to good use. I searched the forums but nobody seems to use the Odroid-U2/U3 for pi-hole.
Since I am no linux wizard I would like to know if there is an easy way to get pi-hole working on this piece of hardware.
Has anyone tried this before?

Thanks

I recently got an Odroid-XU4 to test with HackRF and GNU Radio Companion and remembered this posting.
After having flashed SD and booted the Armbian distro, I dont see any problems installing Pi-hole on Armbian:

$ hostnamectl
   Static hostname: odroidxu4
         Icon name: computer
  Operating System: Debian GNU/Linux 9 (stretch)
            Kernel: Linux 4.14.94-odroidxu4

Its a Debian derivative using the official Debian repos plus some Armbian specific repo's:

$ sudo grep -v '^#\|^$' -R /etc/apt/sources.list*
/etc/apt/sources.list:deb http://httpredir.debian.org/debian stretch main contrib non-free
/etc/apt/sources.list:deb http://httpredir.debian.org/debian stretch-updates main contrib non-free
/etc/apt/sources.list:deb http://httpredir.debian.org/debian stretch-backports main contrib non-free
/etc/apt/sources.list:deb http://security.debian.org/ stretch/updates main contrib non-free
/etc/apt/sources.list.d/armbian.list:deb http://apt.armbian.com stretch main stretch-utils stretch-desktop

And I believe architecture is a supported one:

$ arch
armv7l

Not sure which image works for Odroid-U3 but you could try the Odroid-XU4 "Armbian Stretch" one as HW is similar:

Have you tried installing Pi-hole already via the recommended install method ?

EDIT: Ps. I wont be installing Pi-hole on the Odroid because its not mine.
