Hello Emmanuel, Thank you very much for reporting this bug, and for providing an accurate solution to the problem.
I currently maintain the "frescobaldi" package for Debian, which gets imported into Ubuntu for every 6 months or so. With your posted solution, I finally realized my carelessness when I made the switch from Python 2 to Python 3 for Frescobaldi 2.18.1+ds1-1 in September 2015, where I removed the Python-2-only "python-pypm" from the dependency list, and failed to add back "libportmidi0". Sorry for causing you the trouble! By the way, python3-pygame, which includes pypm the PortMidi binding for Python, has landed in Debian "experimental". It is also available or from the upstream PyGame repository at https://bitbucket.org/pygame/pygame/src as src/pypm.pyx and src/pypm.c (compiled with Cython instead of Pyrex), so perhaps other developers or I will eventually use that work to make python3-pypm available. For the time being, "libportmidi0" alone would do. The fix will go into frescobaldi_3.0.0-1 or one of its pre-releases. Thanks again for reporting this issue! Cheers, Anthony P.S. I am not sure if I would have the time to backport the fix to frescobaldi 2.18.x in Ubuntu 16.04... I am not yet a Ubuntu developer... -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1572566 Title: Frescobaldi missing dependency on python3-pypm | libportmidi0 | python3-pygame To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/frescobaldi/+bug/1572566/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
