Dear maintainer,
it seems this bug affects the version of mypaint currently in testing. When I
try to start mypaint I get:
INFO: mypaint: Installation layout: conventional POSIX-like structure with
prefix '/usr'
Traceback (most recent call last):
File "/usr/bin/mypaint", line 293, in <module>
= get_paths()
File "/usr/bin/mypaint", line 241, in get_paths
from lib import fileutils
File "/usr/lib/mypaint/lib/fileutils.py", line 25, in <module>
import lib.helpers
File "/usr/lib/mypaint/lib/helpers.py", line 25, in <module>
from . import mypaintlib
File "/usr/lib/mypaint/lib/mypaintlib.py", line 13, in <module>
from . import _mypaintlib
ImportError: cannot import name '_mypaintlib' from 'lib'
(/usr/lib/mypaint/lib/__init__.py)
This seems to happen because the package ships
/usr/lib/mypaint/lib/_mypaintlib.cpython-39-x86_64-linux-gnu.so but the current
system libpython is at version 3.10.
I can confirm that rebuilding the package installs
/usr/lib/mypaint/lib/_mypaintlib.cpython-310-x86_64-linux-gnu.so and that the
program starts properly in this case.
I think this package should depend on whatever python version is currently the
system default for unstable as mentioned above.
Best regards,
P.
