Krita's Python scripting not working without libpython3.6m.so, which is contained in libpython3.6-dev (development files). Without it Python scripting is not available in Tools > Scripting menu, and error is: Loading Python plugin "" false () () () Could not create /usr/lib/x86_64-linux-gnu/libpython3.6m.so "Cannot load Python library" Downstream bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=896098
In other words: the app seems to be using the unversioned .so file, which should only be present in a developer's machine. Instead it should look for the versioned file.

Git commit 1553c12637e15d77168e6ddad287ccbf0c53075b by Pino Toscano. Committed on 29/05/2018 at 08:45. Pushed by pino into branch 'master'. Fix loading of the Python library Summary: Instead of assuming the unversioned .so symlink will exist also at runtime (which is not the case for binary distros), use the QLibrary features: the SONAME of the Python library is "1.0", so use the unsuffixed filename of Python library with it. Additionally, this extends the loading also to Unices platforms different than macOS (since Boud excluded it in a previous commit), and destroy the QLibrary in case of loading failure.
