What does the prompt look like when you launch `octave-cli` directly from the terminal?

Hmm, it looks like something is wrong with the install. We need to use the cli app in order to communicate properly. Are you able to reinstall octave and try...

Does the flatpack app have a `/bin` dir or otherwise have an `octave-cli` executable in it? If so, you can point your `OCTAVE_EXECUTABLE` environment variable to that executable.

What is the output of: ```bash echo $SHELL ls /var/lib/flatpak/exports/bin ```

You should be able to add: ``` export OCTAVE_EXECUTABLE=/var/lib/flatpak/exports/bin/org.octave.Octave ``` To the end of your `~/.bashrc` file, and then run the following to see if it worked: ``` source ~/.bashrc...

Hi @flizzer, we attempt to mimic what Octave does at startup [here](https://github.com/Calysto/octave_kernel/blob/9803a8e028628d2d31b835ee267af312b83aac2d/octave_kernel/kernel.py#L319). Perhaps something is missing there.

Hi @rshpeley, I suspect this is a difference in the `path` used by `octave-cli` vs. `octave`. Can you please try typing `path` in both and see if `~/octave/control-3.0.0` shows up...

Hi @klonuo, can you please paste the output from `jupyter lab --debug` up to "timed out waiting for kernel" here as well?
