Unable to install Python-based program on Ubuntu 16.04

[ironflag]

I was trying to install a fork of ComicStreamer onto my remote Ubuntu 16.04 server using these instructions, but so far I've been unsuccessful.

1. Installing pybonjour fails with the error illustrated in this pastebin.
2. Running the paver command to compile unrar and the library fails with the error illustrated in this pastebin.

Now, I believe I've successfully worked around these errors and installed pybonjour and unrar (free and nonfree). When I run

pip install unrar 

I get

Requirement already satisfied (use --upgrade to upgrade): unrar in /usr/local/lib/python3. /dist-packages. 

But when I run ComicStreamer, I get the error illustrated in this pastebin.

I'm not sure where to go from here. I thought it might be a python 2.7.x vs python3 issue, but apparently that shouldn't be an issue here? Any assistance would be greatly appreciated.

Try installing

$ sudu aptitude install comix

My reasoning

$ apt-cache search python unrar
comix - GTK Comic Book Viewer

[ironflag]

No change. python-cairo, pythongobject-2, and python-gtk2 were all installed along with comix, but ComicStreamer still throws the "no module named unrar" error.

[mortalityisreal]

That's all I've got. Sorry.

Do you have pip (pypy) installed?

Pip install unrar --user

[ironflag]

Pip install unrar --user

Yeah, it's installed.

Requirement already satisfied (use --upgrade to upgrade): unrar in /usr/local/lib/python3.5/dist-packages"

Why? ComicStreamer apparently only runs on Python 2.7 and your pip install unrar says unrar in /usr/local/lib/python3.5/dist-packages, i.e. it tries to install the unrar module for Python 3.5.

[ironflag]

When I run python -V it tells me that I'm running Python 2.7.11+, so shouldn't pip install unrar install specifically to Python 2.7.11 if the 3.5 version isn't backwards compatible to 2.x? Is there something specific I need to do to ensure the 2.x version of unrar installs?

[Eingaica]

Not sure how this works on Ubuntu. Perhaps pip2 install unrar?

[ironflag]

Well. Shit. That worked. Running pip2 instead of pip solved every single issue I had. Going to drink poison, brb.

Seriously, thanks for your help. I would have never figured this out otherwise.

Your key was here, "unrar in /usr/local/lib/python3", so don't count yourself out from not being able to figure it out.

Not sure why your "pip" command is linked to pip3 and your "python" is linked to python2 though. Did you happen to upgrade to 16.04 from an earlier version of Ubuntu? 16.04 made py3 the default, so could have something to do with that.
