I think I forgot to answer this question... In a previous package the /etc/jupyterhub/jupyterhub_config.py was generated during the preinst script. two more useless configuration files were distributes in the package /etc/jupyterhub/config/jupyterhub_config.d/<file1> /etc/jupyterhub/config/jupyterhub_config.d/<file2> Now I generate the default configure file during the build put it under /usr/share/jupyterhub/jupytherhub_config.py and manage it via ucf. remove the useless <file1> and <file2> via the rm_conffile. but at the end, piuparts tell me that 2m59.4s INFO: Warning: Package purging left files on system: /etc/jupyterhub/ owned by: jupyterhub /etc/jupyterhub/config/ not owned /etc/jupyterhub/config/jupyterhub_config.d/ not owned 2m59.4s INFO: PASS: Installation, upgrade and purging tests. /etc/jupyterhub comes from debian/dirs in order to avoid failure during the ucf config file generation. So now I need the right way to remove /etc/jupyterhub/config/jupyterhub_config.d/ and /etc/jupyterhub/config/ Is it clearer ? Cheers
