I cannot install ipython package on WSL with Ubuntu 20.04 on Windows 11: "Package ipython is not available, but is referred to by another package."

I'm trying to install ns-3 on my Windows 11 using Ubuntu 20.04 (WSL), but when running:

sudo apt-get install python-pygraphviz python-kiwi python-pygoocanvas libgoocanvas-dev ipython

I get:

Reading package lists... DoneBuilding dependency treeReading state information... DonePackage ipython is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another sourceE: Unable to locate package python-pygraphvizE: Unable to locate package python-kiwiE: Unable to locate package python-pygoocanvasE: Unable to locate package libgoocanvas-devE: Package 'ipython' has no installation candidate.

I've already tried all other instructions, but nothing helped. I tried sudo apt install -y python3-pip, pip3 install ipython, etc.Please, someone help.
