Hi everybody,

Frescobaldi was running fine but today I try to open it and got this errors:

I have no idea how to fix it... Can someone help me?
I am running Frescobaldi 3.1.2 with Lilypond 2.21.6 on Kubuntu 20/04.

I appreciate any help.

Stay safe,

James

How did you install python-poppler-qt5?
Can you paste the output of:

frescobaldi --version-debug

If you compiled some dependency, this discussion may help you:

Hi Federico,
I installed python-poppler-qt5 using "apt install". I followed this guides:
https://github.com/frescobaldi/frescobaldi/wiki/Run-Frescobaldi-3-on-Linux

this is the output from: frescobaldi --version-debug

I will check the link.

Are you sure there's no other installation around (which you may have
forgotten)?

I would check it this way:

$ python
Python 3.9.0 (default, Oct 6 2020, 00:00:00)
[GCC 10.2.1 20200826 (Red Hat 10.2.1-3)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import popplerqt5
>>> import inspect
>>> inspect.getfile(popplerqt5)
'/usr/lib64/python3.9/site-packages/popplerqt5.cpython-39-x86_64-linux-gnu.so'

If you see a different path (e.g. in /usr/local or ~/), try removing
that installation.

If you cannot import popplerqt5, use find to check:

$ sudo find /usr/ -name 'popplerqt5*'
/usr/lib64/python3.9/site-packages/popplerqt5.cpython-39-x86_64-linux-gnu.so

$ find ~ -name 'popplerqt5*'

Hello all !
Sorry to revive this forgotten thread, I'm coming more or less into the same issue, after quite a few updates on my computer (ubuntu 18.04->20.04). I had the default repo version (3.0 or so) and it stopped working after the update. I uninstalled and purged and then tried to grab the last source, but it also failed to start when trying to run directly without install.

Here's the output :
Traceback (most recent call last):
  File "/home/yann/Softs/frescobaldi-3.1.3/frescobaldi_app/plugin.py", line 79, in instance

From your messages above, I thought it may have been a popplerqt5 issue, so I updated my version using pip3.

When I launch python and try "import popplerqt5" it fails :
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: /usr/lib/x86_64-linux-gnu/libQt5Core.so.5: version `Qt_5.15' not found (required by /home/yann/.local/lib/python3.8/site-packages/PyQt5/QtCore.abi3.so)

Any clue ? Might be a version problem somewhere as I first installed some packages via the manager, and then updated through pip, but I don't know where to look.

Thanks in advance for your help (and for frescobaldi - eager to use it again after quite some time !)
Yann

Yes, I think that's the problem.
It seems that your PyQt5 (pip) installation in ~/.local is not
compatible with your system Qt5 library in /usr/lib.

I would remove all the relevant packages installed via pip and use the
distro packages, as it's more likely to work correctly.

pip list --user
pip uninstall PyQt

PS
If you want a quick solution, you can install Frescobaldi as flatpak:
https://www.flathub.org/apps/details/org.frescobaldi.Frescobaldi

Flatpak was designed also to avoid this kind of problem.

Hello Federico !
Grazie mille for your answer.

pip uninstalling PyQt5 solved the problem. I had to do it as well for python-poppler-qt5 that I updated via pip as well (I thought, the more recent, the better it is ! :)
I was missing a couple of other dependancies, but now it seems everything is working fine.

I never used flatpak before and didn't see the option on the website. Is the link given somewhere on frescobaldi.org ?
I think it is a very good idea. Now that it's working fine on my system I'll keep it as it is, but I'll probably use flatpak at next frescobaldi update.

Best regards,
Yann

I am usually using Lilypond 2.23. Now I returneds to Lilypond 2.20 and Frescobaldi starts without error.

This has been in my TODO list for a long time... just pushed a PR:
