Dear Damon,
to start with, a massive thanks for your brilliant piece of software, I don’t know how I ever managed without it!
I was wondering if there is any way/hope of getting RPD to work on ARM devices? I have a new Pinebook Pro with an ARM based Rockchip RK3399 SOC running Debian 10.
I spend a lot of time away from home and would love to be able to download my photos to the Pinebook Pro while away from my main machine.
Stay safe and keep up the good work!
Have you tried running the installer? Its python, so it should run OK on arm.
It is packaged in Debian, in stable / testing / unstable. I do not own an ARM laptop so I have never tried it. As expected the package in stable is many years old.
Thank you for the very quick reply!
I feel quite silly now, it is indeed packaged and it installed perfectly from GNOME Software… 
It’s version is 0.9.13, from November 2018.
I had just gone straight to the install script like I always do and didn’t even think of checking the repositories…
Thanks again!!
Thanks paperdigits,
as you can see above I went straight for the installer but that failed.
Just in case there might be an easy fix, I’ll (try to) post the terminal output here:

Version 0.9.13 is really a very old version. Let’s try to figure out why the Python package Pillow is not installing on your system. Do this:
python3 -m pip install -v -U pillow
And copy and paste the error output here.
over 2300 lines of output from that! 
When I try to post that I get the following warning:
“Body is limited to 50000 characters; you entered 680667.”
I’ll therefore upload the output in a text file.

Is this package installed?
libjpeg62-turbo
It is, newest version (1:1.5.2-2+b1).
You could upgrade to a distro that ships newer versions. instead of sticking to old distros 
As ARM based laptops are not yet mainstream there are not a lot of options for the Pinebook Pro if you want an proper installer that supports full disk encryption instead of a a ready made image.
I tried to install Manjaro but failed so opted for Debian, which is also more in my comfort zone as most of my Linux experience is with Ubuntu based distributions so far. I could have opted for Debian 11 Bullseye but decided that being on an ARM based laptop with a hacked 5.5 kernel is bleeding edge enough for me. This is to be my daily driver while being from home for weeks at the time , most of the time. I greatly value stability.
I’m happy to have 0.9.13, getting the installer to work would be a bonus.
It might be the package is so old that recent versions of pillow simply fail to build against it.
Try installing the Debian package python3-pillow and then retry the install.py script.
Brilliant, that did the trick, running 0.9.24 now!! 
Thank you so much!
I’m glad it worked. A future enhancement to the script might be to give the option of prioritizing the installation of distro packages over packages from PyPi.
