Package ipython-notebook is not available, but is referred to by another packag. This may mean that the package is missing, has been obsoleted, or is only available from another source
E: Package 'ipython-notebook' has no installation candidate
Do you already have python installed? If so, try:
sudo apt-get install ipython
or if you have pip:
pip install ipython ipython-notebook
Regardless, I instead recommend installing Anaconda or Miniconda from:

This will help you setup virtual environments and packages.
Anaconda contains all library that is useful.In IPython you have to install different-different libraries.
I installed ipython via apt, and then went the pip and virtualenvwrapper route for ipython-notebook, which worked for me. The commands were:
sudo apt -y install ipython mkvirtualenv ipynb pip install ipython[notebook]
Alternatively:
sudo apt -y install ipython mkvirtualenv ipynb pip install ipython[all]
FWIW, I ran into this error when trying to run the following command on a freshly spun up Ubuntu 18 image (on AWS, ami-0ac019f4fcb7cb7e6):
sudo apt-get install ipython3 E: Package 'ipython3' has no installation candidate
Running an apt-get update solved the problem. So:
sudo apt-get update sudo apt-get install ipython3 Interestingly, I was surprised to find that this particular distro doesn't come with Python 2.7 installed, only Python3. That's probably AWS just trying to keep things light, which I appreciate.
Hopefully this helps someone down the line.
As virtually every Linux distro, Ubuntu comes with Python 2.7 pre-installed. In order to execute your Python code, you open your terminal, cd to the directory where the script is and run python script.py
apt-get update. because apt or apt-get doesn't know about what you're talking about and can be solved by updating. Let me know if it worked for you or not .pip install ipythonorsudo apt-get install ipythonand similar things should go for python3
