I haven’t seen a flatpak of RPD either, and I’ve been looking. Its on my list of things to try, and I enquired about it in the flatpak IRC a while ago and got some advice.
The nice thing I’ve found about flatpak is that the community is helpful, so if I can pull something together, there is a strong possibility to get help with the final bits.
I think you have identified something important there, because almost always, something goes wrong and you cannot fix it yourself. The snap community is also helpful and engaged, but the point-person for the bug I encountered with snap wanted to me to fix it, and I just don’t have time these days to be contributing to other projects.
Dear @damonlynch
thank you very much for your comprehensive explanation.
Typically gentoo is quit up to date and compile everything acc to loacal machine setting locally. It should be a perfect harbour for RPD 
I wish I could promise to be a good ebuild maintainer, unfortunately I know, I cannot (tooooooo many other things…)
For the time being I’m happy, that also my PC after laptop installed 0.9.17 nicely…
Sincerely
Axel
@damonlynch
how is your dissertation going on?
gentoo has changed to python 3.7 as its default. I guess due to this RPD does not work anymore on my laptop (PC yet to be tested).
So I downloaded the install.py again and started with: python3.7 install(1).py
and I got:

ModuleNotFoundError: No module named 'raphodo'
Is there a way to get it back to work again?
Thanks in advance!
openSUSE Tumbleweed is on python >= 3.7 for a while and our rpd package works very nicely with both python versions (3.7.x and 3.8.x). maybe someone could just do an ebuild or rpd?
It’s going well thanks but I need to finish it 
You need to install the gentoo package for PyGObject (which in turn requires pycairo). I have no idea what those two packages are called on gentoo, sorry.
Rapid Photo Downloader works with Python 3.4 - 3.8.
And yes, it would be great if someone did an ebuild.
both are installed already and up2date prior my todays initial post… so I’m stuck here 
So you are sure you have this package installed?
But at the same time if you run this from within python3, this fails?
import gi
gi.require_version('Gdk', '0.3')
If so, something is broken.
@AxelG
First I would like to know where to find the ebuild you use.
To the problem: As you know Gentoo allows you to install different versions of certain packages at the same time (-> slots). So the obvious question: After updating python to 3.7 did portage rebuild all python modules? If not simply run emerge -uDN @world to get a deep (=including all dependencies) update picking up USE-Flag changes.
Equally important is that after the python update you set the system python interpreter to python3.7. emerge won’t uninstall python-3.6 by itself. So first use eselect python to set the interpreter to python3.7, then emerge -C python:3.6
(What I don’t understand ATM: RPD is a PyQT5 application, so what do you need gdk for?)
Short answer: That’s a remnant from version 0.9.22 that should be removed.
Longer answer: Version 0.9.22 used Gdk to detect if any screens had scaling enabled very early in application startup. Using Qt to detect the scaling that early in the application lifetime would fail on a Gtk based desktop, because Gtk and KDE take different approaches to low level X settings. The code using Gdk was removed in 0.9.23 and replaced with code that probes xsettings instead. Detecting scaling very early in application start up is needed because simply enabling HighDPI scaling when it was not needed (i.e. system scaling is 1.0) resulted in severe window rendering corruption on some Gtk desktops.

As you could see from this thread above, there is no ebuild, I use the install.py from the homepage
that is indeed in my /etc/cron.weekly (together with an eix-sync)
It would be embarrasing if I wouldn’t
$ eselect python list
Available Python interpreters, in order of preference:
[1] python3.7
[2] python3.6
[3] python2.7
[4] python3.8 (fallback)
Hmmm as we see from above, python 3.6 is still there, I knew that, just have difficulties to believe, this would make any difference. Lensfun still need 3.6 hence I won’t uninstall 3.6 atm…
Sorry, I meant you had to run the Python interpreter from within a terminal window and run those two commands within the interpreter, not from the shell. In any case, it’s somewhat irrelevant because you don’t need gdk in Rapid Photo Downloader >= 0.9.23. I have updated the install.py script to reflect this.
Delete the current install.py script and download and use this one (enter the command on one line):

@damonlynch
first of all thank you very much.
I did so and installed afterwards.
Running it caused me the following:

Should I have uninstalled something manually?
That indicates a problem in the python package tenacity in your system. I don’t know the steps that led to this problem, because I don’t use gentoo. That’s something you’ll need to figure out in order to get any program working that uses tenacity.
I checked with equery check tenacity. Seems clean … 
which version is minimum required?
@damonlynch
together we made it. THANK YOU SOOO MUCH
upgraded to tenacity-6.1.0 and that further pulled dev-python/futures-3.1.1 and virtual/python-futures-1
now it works
sorry for being your PITA today…
on my laptop during installation I saw a weird message about upgrading PyQT5 from 4.xx.yy to 12.xx.yy.
mit-krb5 is needed, but not checked and missing on my laptop. So a matter of time
After successfull installation RPD still don’t wanna work…
And uppon execution, file or folder not found for libgssapi_krb5.so.2
$ ./rapid-photo-downloader
Traceback (most recent call last):

usually bith machines are the same up2date… I will run another update now anyways, which on this older lenovo T450s will take some time
Anything to rebuild with emerge -avt @preserved-rebuild?
revdep-rebuild might fix it, too.
I got to see I was too impatient and started a @system @world (indeed with lots of opts). No worries, I will make it from here.
TNX
after installing virtual/krb5 now RPD also works on my laptop (PC has krb5 thru samba)
@damonlynch again thank you very much for your swift support and this great piece of software
(embarrassing mistake corrected 
)
