I installed sage from the command line initially with 'sudo apt .....' and subsequently wanted to run the version from source. I have installed the source file successfully now but on the command line the older version runs when sage command is typed. I realize that the SAGE_ROOT path needs to be specified again and would want to know what is the best way to do this ?
You cannot run sage from source code, maybe you mean from a binary. I will assume that you have download the tar.bz2 file for sagemath in ubuntu from the web of sage. Then first uninstall the sage installed with sudo apt, this is to free space as you will not use this anymore. Now go to the folder where you have unzipped the tar.bz2 file and copy it direction to add it to the $PATH, to do this follow these instructions.
Once you have done this maybe you will need to reboot the system, and then you can call sage from any terminal just with the command sage.
If I understand correctly, you have installed Sage both
sudo apt install ...make configure, ./configure, and makeLet's say your installed-from-source Sage is at /home/yourname/sagemath/sage,
then you add an alias to it and place it to some directory that is in your PATH.
For example:
ln -s /home/yourname/sagemath/sage /usr/local/binor with sudo if necessary:
sudo ln -s /home/yourname/sagemath/sage /usr/local/binAfter that, running sage should run the Sage you want.
