Failing to launch Octave Kernel (Ubuntu 20.04)

Hi there!

So I've been trying to get this kernel to work for sometime now with no luck. I've tried both methods described in the README, and I always get the same error.

[I 2020-12-31 06:12:03.848 ServerApp] Kernel started: a266612c-98a4-4fd1-b2bf-72b4154c3505 /usr/bin/python3: No module named octave_kernel [I 2020-12-31 06:12:06.848 ServerApp] KernelRestarter: restarting kernel (1/5), new random ports /usr/bin/python3: No module named octave_kernel [I 2020-12-31 06:12:09.855 ServerApp] KernelRestarter: restarting kernel (2/5), new random ports /usr/bin/python3: No module named octave_kernel [I 2020-12-31 06:12:12.864 ServerApp] KernelRestarter: restarting kernel (3/5), new random ports /usr/bin/python3: No module named octave_kernel [I 2020-12-31 06:12:15.870 ServerApp] KernelRestarter: restarting kernel (4/5), new random ports /usr/bin/python3: No module named octave_kernel [W 2020-12-31 06:12:18.877 ServerApp] KernelRestarter: restart failed [W 2020-12-31 06:12:18.877 ServerApp] Kernel a266612c-98a4-4fd1-b2bf-72b4154c3505 died, removing from map.

I'm on Ubuntu 20.04.

It looks like you have octave_kernel installed in a different place than jupyter, which is installed in /usr/bin/python3 on your machine. You could try installing the kernel as /usr/bin/python3 -m pip install octave_kernel, and then run jupyter kernelspec list to make sure it was discovered.
