Python 3.6 is pretty old. Although it’s technically supported by RedHat/CentOS that only applies to the packages managed directly by the distribution- many Jupyter projects no longer support it. It’s possible the error you’re seeing is due to an incompatibility between Python 3.6, Jupyter notebook, and its dependencies.

Can you try a more recent version of Python, e.g. 3.10?

thanks，
python3.8 has same error. btw, I use ldapauthenticator that can create user and login suceesfully.

finally , the default configuration “c.NotebookApp.terminado_settings” must set a value like
c.NotebookApp.terminado_settings = {‘shell_command’: ‘/usr/bin/bash’} and change user bash when created
