I was attempting to set the default python variant to python3 in Ubuntu 16.04. As a matter of course, it is python2 (2.7). I followed the underneath steps : 

update-alternatives --remove python /usr/bin/python2

update-alternatives --install /usr/bin/python python /usr/bin/python3

however, I'm getting the accompanying blunder for the subsequent assertion, 

rejeesh@rejeesh-Vostro-1015:~$ update-alternatives --install /usr/bin/python python /usr/bin/python3

update-alternatives: --install needs <link> <name> <path> <priority>

Use 'update-alternatives --help' for program usage information.   

I'm new to Ubuntu and I don't have the foggiest idea what I'm fouling up.

I Suggest, update-alternatives is the better method to do this. 

Open your .bashrc document nano ~/.bashrc. Type alias python=python3 onto another line at the highest point of the document at that point spare the record with ctrl+o and close the document with ctrl+x. At that point, back at your order line type source ~/.bashrc. Presently your assumed name should be lasting.
