pkg_resources.DistributionNotFound: The 'dbus-python' distribution was not found and is required by jack-select

I am under ubuntu 18.04, and python3-dbus is installed. When I run the python3 interpreter, and issue an " import dbus ", it is working as expected. I did a "sudo make install" install, which installed to /usr/local

Yes, unfortunately the dbus-python package, when installed via your Linux distribution's packages, does not register itself correctly as a setupotools compatible package. Thatswhy I patch the setup.py file to remove the explicit dbus-python dependency in my AUR package for jack-select.

The dbus-python package has been marked as outdated now, so I should probably switch to pydbus, but that will probably not happen for another few weeks.

I can only recommend to either edit the setup.py file yourself and remove the dbus-python dependency or install jack-select into a virtualenv. This will install all the dependencies (dbus-python, PyGObject and pyxdg) from PyPI instead of from your distribution packages and will install them into the virtualenv in a way that satisfies the setuptools dependency check. You'll need to have a compiler and the python development headers installed, though (install package build-essential and python3-dev), since some packages are not available as binary wheels on PyPI and need to be compiled on your system (e.g. pycairo).

ok. thanks
removing python-dbus package from install_requires, I get

update-desktop-database -q
gtk-update-icon-cache /usr/local/share/icons/hicolor
gtk-update-icon-cache: No theme index file.
Makefile:25: recipe for target 'install' failed
make: *** [install] Error 1

because of gtk-update-icon... which I can then disable.

then when I run it:

I was able to setup a virtualenv, then install the dependencies, but when I try to install, I get

python3 setup.py install --prefix=/opt/jack-select/
running install
Checking .pth file support in /opt/jack-select/lib/python3.6/site-packages/
/usr/bin/python3 -E -c pass
TEST FAILED: /opt/jack-select/lib/python3.6/site-packages/ does NOT support .pth files
error: bad install directory or PYTHONPATH

You are attempting to install a package to a directory that is not
on PYTHONPATH and which Python does not read ".pth" files from.  The
installation directory you specified (via --install-dir, --prefix, or
the distutils default setting) was:

    /opt/jack-select/lib/python3.6/site-packages/

and your PYTHONPATH environment variable currently contains:

    ''

Here are some of your options for correcting the problem:

* You can choose a different installation directory, i.e., one that is
  on PYTHONPATH or supports .pth files

* You can add the installation directory to the PYTHONPATH environment
  variable.  (It must then also be on PYTHONPATH whenever you run
  Python and want to use the package(s) you are installing.)

* You can set up the installation directory to support ".pth" files by
  using one of the approaches described here:

  https://setuptools.readthedocs.io/en/latest/easy_install.html#custom-installation-locations


Please make the appropriate changes for your system and try again.

It seems that your QjackCtl.conf file has a line in the [Settings] section, which does not conform to the expected format.

Did you create any presets with QjackCtl at all before starting jack-select? Can you post the contents of the [Settings] section of your QjackCtl.conf file here? It should be in the ~/.config/rncbc.org/ directory.

I have some startup scripts defined, could that be the source of the error? qjackctl version is qjackctl_0.5.3.10git.06f15c-1_amd64 from rui's suse-openbuildserver repository

I have now renamed my qjacktl config folder, then generated a new one, and jack-select runs.
but there is something strange with qjackctl: it starts jack, then displays an error message it could not start jack, but then it starts it anyways, but jack is the using all CPU cores, jack-select tray icon does not
get green.

I also tried with cadence, which works flawlessly, also, jack-select does get green and red in tray when using start and stop jack in cadence. I will try to find out the differences to my setup and the vanilla one...

https://pastebin.com/nUL2sMiM would be the vanilla one qjackctl created. I see there is no[Settings] section...

https://pastebin.com/edXRTZrz would be mine..

I have tried to narrow down the problem, but it seems to be a problem on your side...
even with only

[Settings]  
Audio=0

it gives the same error... If I remove that last line the error message disappears

[SpotlightKid]

The problem was, that if you have only the default preset saved in QjackCtl, its configuration file, resp. the Settings section, has a slightly different format than when you have one or several custom presets, and jack-select didn't handle this correctly. This should be fixed in version 1.1.1, which I just released.

I also tweaked the Makefile to ignore the error when running gtk-update-icon-cache and added some hints to the readme on how to solve installation problems.

[SpotlightKid]

I opened #2 to track the task of replacing dbus-python. I'll close this issue, since the other issues you mentioned should be fixed. Feel free to re-open this issue if you still have problems regarding these issues with version 1.1.1. If you should encounter other problems, please open a new issue.

[revast]

thanks a lot!
I always wanted to have means to visually see the status of JACK, and not having cadence or qjackctl running for that.
Very cool to have one now. The Presets integration tops it - Really handy if you have more the one device and you switch them often.
