python-wxgtk2.8 required, but Ubuntu 16.04 ships python-wxgtk3.0

The control file in the .deb file has a "Depends:" line that includes python-wxgtk2.8|python-wxgtk3.0 which when installed using gdebi should allow either 2.8 or 3.0. If that is not the case try opening the .deb file with your archive manager and editing /DEBIAN/control so that the reference to python-wxgtk2.8 and the "|" character are removed leaving just python-wxgtk3.0
Within the code, I only ever import wx so it should run with whatever version you have installed.
Let me know how you get on.

Here are the depencencies that I found in fs2-equaliser_1.5.0_all.deb:

Depends: python (>= 2.7), python-wxgtk2.8, pulseaudio (>= 4.0),pulseaudio-utils, swh-plugins, cmt, ladspa-sdk,bs2b-ladspa

I managed to install it using:

dpkg-deb -R fs2-equaliser_1.5.0_all.deb unpacked
sed -i 's/python-wxgtk2.8/python-wxgtk3.0/' unpacked/DEBIAN/control
dpkg-deb -b unpacked fs2-equaliser_1.5.0_all-patched.deb
sudo dpkg -i fs2-equaliser_1.5.0_all-patched.deb

After that I can run fs2_equaliser.

Good morning Falko,
I have just received a raft of your emails and I'm pleased to note that through perseverance and skill you have managed to get it working.
Congratulations!
I can only assume that, I updated my build with the
"python-wxgtk2.8|python-wxgtk3.0" option and then singularly failed to post the updated build to sourceforge.
I shall sort that out later this weekend.
In the mean time your efforts, now document an excellent workaround for anyone else in the same predicament.
Thank you for taking the time to post your solution.
Regards
Rolf
