Please update to the latest version of Navigator.

Open a terminal (on Linux or Mac) or the Anaconda Command Prompt (on windows)
and type

$ conda update anaconda-navigator

I am trying to open the jupter notebook either through the jupyter notebook or the console and the above error is what i repeatedly get. I have installed the anaconda software using administrator access. Any help to launch the notebook would be appreciated.

Hi, even after updating the Navigator I encounter the same issue again. I have restarted my laptop post the navigator update.
