Frescobaldi 2.18 install problems on KXStudio

[Colin Campbell]

After manually running updatedb and locate, then deleting any instance of frescobaldi and python-ly in /usr/* in order to remove prior version conflicts, I ran
sudo python setup.py install from the unzipped source directory, which finished as below (emphasis added):

***********************************
The log output shows python-ly being fetched from pypi and apparently installed in the same directories as the frescobaldi code.
Running Frescobaldi gives me an error box with the following text:

**********************

We are sorry, but Frescobaldi can't run properly.

The python-ly package is not available or too old.

At least version 0.9 is required to run Frescobaldi.

If you did install python-ly correctly, please remove the old

ly package from the frescobaldi_app directory, or completely

remove and then reinstall Frescobaldi.

**********************************

Having been an early adopter of Frescobaldi, even when it was still lilyKDE, I'm a bit taken aback at the challenges of this update. I realise it is quite likely I've missed an important instruction and I'm more than happy to be corrected.

Cheers,
Colin
