nbterm - new notebook not running

[amrrs]

When I use nbterm new_notebook.ipynb it displays a notebook but when I try to run something in the cell like 2+2 it just shows that it's executing but nothing seems to happen, I doubt if it's because no Kernel is initialized ?

I've multiple kernels like R, python and Jupyter notebook usually initializes with Python.

[amrrs]

Probably my assumption is wrong, when I run it with no-kernel nothing happens like executing. so it's something else.

[amrrs]

Just to add, If I open an existing jupyter notebook (Python kernel) it works just fine.

I'm wondering what are these ^Z^Z in you cell, maybe it's because of that?

[amrrs]

No that was actually me trying to figure out different options to exit as Ctrl+q wasn't working as well

Did you get any error message when starting nbterm (before seeing the notebook)?
Did you exit the cell (with Esc) before you run (Ctrl-r)?

I just installed nbterm and I have the same issue including "ctrl-q" not working.

I got an error message.

Existing notebooks are also not running

After installation under python 3.9.5 it does not run cells in a new notebook nor in existing notebooks. The status line says

python3 (busy)

From then on, it is not possible to quit nbterm other than quitting the terminal.
I see that I have to quit twice because of unsaved changes, but that does not work.
When I save, and then press Ctrl-Q, nbterm still does not exit.
