I suspect that having user and group called same
is the clue
I noticed this phenomena in launching the jupyter lab.
File "/usr/lib/python3.8/site-packages/jupyter_core/paths.py", line 909, in
secure_write
raise RuntimeError("Permissions assignment failed for secure file:
'{file}'."
RuntimeError: Permissions assignment failed for secure file:
'/home/user/.local/share/jupyter/runtime/jpserver-27580.json'. Got '0o644'
instead of '0o0600'.
Workaround for the jupter lab error is
export JUPYTER_ALLOW_INSECURE_WRITES=true
