Install GeoNode 4.1.x on Ubuntu 2004

[gaowqspace]

I want to install GeoNode 4.1.x on Ubuntu 2004. But when I try to follow GeoNode project installation documentation, there are some errors.

Step: # Install the Python packages
pip install -r src/requirements.txt --upgrade
Error message: ERROR： No matching distribution found for ipython==8.13.2

In the GeoNode documentation, Ubuntu 2004's default Python version is 3.8, but ipython==8.13.2 requires Pthon>=3.9.

I think this error must be debug in Documentation.
