From the official website, there are several methods to install sagemath.
The easiest one is to run the following commands:
sudo apt-get install build-essential m4 dpkg-dev
sudo apt-get install sagemath
For more details about the different installation methods, please visit the installation guide

If you have downloaded the file sage-8.8-Ubuntu_18.04-x86_64.tar.bz2, extract the folder sage-8.8-Ubuntu_18.04-x86_64. It contains a single folder SageMath. Move SageMath to any location of your choice (I put it in the folder ~/Sage). Open SageMath and run the executable file ./sage
. That should set up Sage. You can then open the terminal version by running~/Sage/SageMath/sage
and the notebook version with one of the following ~/Sage/SageMath/sage --notebook=jupyter
(the new notebook interface), ~/Sage/SageMath/sage --notebook=sagenb
(the old notebook interface), or ~/Sage/SageMath/sage --notebook=
(a prompt to choose which interface you want). I like to put these in bash scripts in my ~/.local/bin
. After installation the HTML version of the documents can be easily accessed by opening ~/Sage/SageMath/local/share/doc/sage/html/en/index.html
in a web browser.
