Hi,
I have now installed Linux Mint 18.3 (based on Ubuntu 16.04) on a
computer and installed Frescobaldi 3 through apt without *any*
issues.
First I did
sudo apt install python3-pyqt5 python3-pyqt5.qtsvg
python3-pyqt5.qtwebkit git
Then I cloned the repositories of python-ly and frescobaldi.
When I launched Frescobaldi using
PYTHONPATH=$PYTHONPATH:/path/to/python-ly
Frescobaldi starts, but doesn't open the Music View (because Poppler
is missing, of course)
Then I tried
sudo apt install python3-poppler-qt5
upon which Frescobaldi started correctly with both SVG and PDF
viewers
working.
This tells me that the Ubuntu packages are now working properly even
for Ubuntu 16.04.
There's one caveat that *might* be happening in addition: I am using
a
previously existing $HOME directory, so there *might* be something I
had already configured earlier. But actually I'm quite sure this is
not the case, as before installing python3-poppler-qt5 it was not
detected at all, while after installation it worked properly.
I will write a post to the list with some more reasoning, just to
have
it recorded publicly.
Best
Urs

Does that mean you run the `setup.py` file from Frescobaldi? I
have
never done so, and in "my" instructions this is not mentioned.
I first tried with " python3 frescobaldi". But "python3 frescobaldi"
does display the icon only for short time and disappears, as
described
in the past mails. Then I read the INSTALL document of
fresobaldi-3.0.0 and experimented further. I will repeat to
load/install the libs and try again without using "sudo python3
setup.py install" from frescobaldi-3.0.0.
In a first step I installed PyQt5 from
https://pypi.python.org/pypi/PyQt5 [2] with
"pip3 install PyQt5"
My suspicion is that after having manually installed
python-poppler-qt5 from the Git repository using "setup.py" from
Frescobaldi will essentially trash that effort by installing the
package from the repositories.
I tried to install python-poppler-qt5 (again).
Actually this is what I would have suggested, *re*install the
poppler package from the repository and then *not* run Frescobaldi's
installer again.
I reinstall with

cd ~/git git clone https://github.com/wbsoft/python-poppler-qt5 [1]
cd
python-poppler-qt5 python3 setup.py build sudo python3 setup.py

and check with idle3:

Something wrong ?
I argued that this has something to do with PyQt5 etc? so I tried
~/python-poppler-qt5 $ python setup.py build ... omitted lines ...
File "setup.py", line 216, in __find_pyqt_sip_flags from PyQt5
import QtCore ImportError: No module named PyQt5
~/python-poppler-qt5 $
Well, this seems clear: you probably don't have a PyQt5 package
installed for Python *2*. You should do `sudo python3 setup.py
build` (using Python 3).
As mentioned above:
In a first step I installed PyQt5 from
https://pypi.python.org/pypi/PyQt5 [2] with
"pip3 install PyQt5"
I tried it with a version ~/python-poppler-qt5-0.24.2 and got the
message ... omitted lines ... File "setup.py", line 156, in
finalize_options self.pyqt_sip_flags =

__find_pyqt_sip_flags from PyQt5 import QtCore ImportError: No
module named PyQt5 ~/python-poppler-qt5-0.24.2 $ Beforehand that
python-poppler install trials I installed pyqt5-dev,
pyqt5-dev-tools, python3-pyqt5, python3-pyqt5-qtsvg,
python3-pyqt5-qtwebkit from repository for any eventuality as
well. Actually just now as an experiment I installed python-pyqt5
version 5.5.1+dfg-3ubuntu4 (from repository) and tried the above
again and get lots of deprication warnings. Deinstalled and get
the above now again. Points in the direction of Version problems?
Yes. python-pyqt5 is the PyQt5 version for Python 2, so when you
run
setup.py with Python 2 you won't get the error about "no module
PyQt5" anymore, but the rest of the code isn't compatible anymore.
As mentioned above:
In a first step I installed PyQt5 from
https://pypi.python.org/pypi/PyQt5 [2] with
"pip3 install PyQt5"
I cannot find the source? I always find "pip3 install PyQt5" - that
is
what I have done
https://pypi.python.org/pypi/PyQt5 [2]
http://pyqt.sourceforge.net/Docs/PyQt5/installation.html [3]
Should I send this clarification to Github as well?
I don't think so for now. Let me look closer into this (I will
install Mint 18 on the PC when I'm allowed to shut down Windows ;-)
). But maybe reinstalling python-poppler-qt5 from the Git repository
with Python 3 brings you forward anyway? (Just don't run the
Frescobaldi installer afterwards. Actually this is not necessary at
all when you have the dependencies already installed manually. Good
luck Urs
Kind regards BB PS: I know Python cursorily and did not become a
fan, so I am not good enough to be of help.
I think it's less of an actual *Python* problem but more generally
related to package management.
In a last check of
python3 frescobaldi
the behavour is unchanged.
The result is negative and confirmes my past result that I never got
version 3 to work on a ubunto prior to 17. As I mentioned I have
working frescobaldi3 on a linux version based on ubuntu 17.
May be the problem is inherent in something with the GUI based Linux
Mint? One might check other linux versions and as you reported you
have installed on Linux. Which brand?
