I gather from the various places you’ve been posting about your installation woes (i.e. reddit) that you’ve encountered several problems during installation, not all of which you cover above. My guess is that somehow your system has gotten into a state where it’s difficult to install anything new using python packaging tools because of previous errors.
I’ve installed the program on Linux Mint so I know it works. So the best solution is to start afresh. List what you have installed:
damon@LinuxMint ~ $ pip3 list --user
arrow (0.8.0)
colorlog (2.10.0)
colour (0.1.2)
easygui (0.97.4)
gphoto2 (1.5.0)
psutil (5.0.0)
pymediainfo (2.1.5)
PyPrind (2.9.9)
python-dateutil (2.6.0)
pyxdg (0.25)
pyzmq (15.1.0)
rapid-photo-downloader (0.9.0a5)
rawkit (0.5.0)
six (1.10.0)
sortedcontainers (1.5.4)
You are using pip version 8.1.1, however version 9.0.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.
Now uninstall everything related to Rapid Photo Downloader. I have listed them below. You probably won’t be able to uninstall all of them because they’re probably not all installed, so figure out which ones from the list below apply:
damon@LinuxMint ~ $ pip3 uninstall arrow colorlog colour easygui gphoto2 psutil pymediainfo PyPrind python-dateutil pyxdg pyzmq rapid-photo-downloader rawkit sortedcontainers
Hit y when prompted to do so for all the packages. Don’t remove six as it’s a general tool unrelated to Rapid Photo Downloader.
Next ensure you have downloaded the updated install.py script using the instructions I noted to another user earlier in this thread. That updated install.py fixes some problems on Linux Mint.
If Rapid Photo Downloader doesn’t install report back here.
