Actually there is a probably a configuration file, but not in the place where I checked, I assume.
I have Ubuntu or Ubuntu based test installations in partitions sda6,7,8,9,10. I can not recall in which partition in actually happened. However I found out about the command [1] jupyter --paths And I did this in some of the different test installations [2] In sda8 I have user8@Latitude2:~$ ls /usr/share/jupyter kernels nbextensions user8@Latitude2:~$ ls /usr/share/jupyter/kernels python3 user8@Latitude2:~$ ls /usr/local/share/jupyter/kernels pharo So the probable explanation is that there was actually a configuration file but not in /usr/local/share/jupyter/kernels/pharo as you indicate in https://github.com/jmari/JupyterTalk/blob/master/README.md but in /usr/share/jupyter/kernels So my guess is that a download *nteract* (https://www.nteract.io/) alone and pharo6.1 with Juyptertalk (thus no python notebook) should work in a new Linux installation if there is a a kernel.json file with Pharo Smalltalk [3] in either /usr/local/share/jupyter/kernels/pharo OR /usr/share/jupyter/kernels/pharo I will test that and report to the list. --Hannes [1] jupyter help ================= user10@Latitude2:~$ jupyter --help usage: jupyter [-h] [--version] [--config-dir] [--data-dir] [--runtime-dir] [--paths] [--json] [subcommand] Jupyter: Interactive Computing positional arguments: subcommand the subcommand to launch optional arguments: -h, --help show this help message and exit --version show the jupyter command's version and exit --config-dir show Jupyter config dir --data-dir show Jupyter data dir --runtime-dir show Jupyter runtime dir --paths show all Jupyter paths.
