I have installed from scratch, from the official debian packages, jupyter itself, and the kernels for ipython (which is auto-installed along with the jupyter installation) and R. Those kernels appear to work as expected.
Now how do I go about re-adding, for example, the bash kernel (which was one of several kernels that used to be available and to work, but now fails to
do so -- any attempt to use it results in a connection failure)? All the various advice I've been able to find online has failed in one way or another, so I would very much appreciate a step-by-step description of what to do in trixie to add a bash kernel.

I don't think the word "kernel" means what you think it means.
This sounds like userspace programming language stuff. Python.

What on *earth* are you even talking about?
Bash is a shell. It's a userspace application, a command interpreter
with both interactive and non-interactive modes.
It comes in a package named "bash". You almost certainly have it
installed:
hobbit:~$ dpkg -l bash | tail -n 1
ii bash 5.2.37-2+b8 amd64 GNU Bourne Again SHell
Bash is not a kernel. Linux is a kernel. Your kernel packages will
look something like this:
hobbit:~$ dpkg -l linux-image\* | grep ^.i
ii linux-image-6.12.73+deb13-amd64 6.12.73-1 amd64
Linux 6.12 for 64-bit PCs (signed)
ii linux-image-6.12.74+deb13+1-amd64 6.12.74-2 amd64
Linux 6.12 for 64-bit PCs (signed)
ii linux-image-amd64 6.12.74-2 amd64
Linux for 64-bit PCs (meta-package)
Bash, Python, and Linux are three entirely separate things, and they have nothing to do with one another.
What issue are you actually having? If you're running a command which
gives an error, show us the entire terminal session, from your prompt
to the end of the output.

May i inquire what exactly is the goal, because the real distinction is if you actually need ring 0. Python can do either but which do you really need if it's arguing with you?

Note: The word kernel has a specific meaning when talking about
jupyter:

I'm sorry; I thought I was being clear.
