Apostrophe 3.4-2 fails to start on Ubuntu 26.04 with Python 3.14.
Traceback:
TypeError: cannot pickle 'ApostropheTextView' object
The crash seems related to Python 3.14 changing the default
multiprocessing start method on POSIX from fork to forkserver. Forcing
multiprocessing.set_start_method("fork") before launching Apostrophe
works around the issue.
Fix:
mkdir -p ~/.local/share/apostrophe-python314-fix
cat > ~/.local/share/apostrophe-python314-fix/sitecustomize.py <<'PY'
import multiprocessing as mp
try:
mp.set_start_method("fork")
except RuntimeError:
pass
PY
PYTHONPATH="$HOME/.local/share/apostrophe-
python314-fix${PYTHONPATH:+:$PYTHONPATH}" apostrophe
