I've downloaded the precompiled binary for sagemath 9.1(sage-9.1-Ubuntu_18.04-x86_64.tar.bz2), I'm on ubuntu 20.04. After extracting the file when I run ./sage
in the terminal it says bash: ./sage: Permission denied
. I made the file executable by changing the permission but then it says ./sage: no Sage installation found in $SAGE_ROOT = /home/my_pc/Downloads/SageMath
. Can anyone help me with this?

The Sage installation guide says:
If your operating system does not provide SageMath, you can also use a pre-built binary...
Installation from a pre-built binary tarball is an easy and fast way to install Sage.
Note that on GNU/Linux a preferred way is to use your package manager (e.g. apt, pacman, yum).
Sagemath has packages for the following operating systems:
On GNU/Linux Debian version >= 9, Ubuntu version >= 18.04, Arch Linux
there are three packages to install
• sagemath (for the binaries)
• sagemath-jupyter (for the browser interface)
• and the documentation
which is called sagemath-doc-en on Debian/Ubuntu and sagemath-doc on
Arch Linux.
Using Apt-Get
First, try installing sagemath using the following command in your terminal because your OS is higher than Ubuntu 18.04.
sudo apt-get install sagemath sagemath-jupyter sagemath-doc-en
Then you should be able to run sage
from the command line.
Using a Pre-Built Binary
It says you can extract the tarball to a folder in your home directory and run ./sage
, which it seems you have done. If it didn't work from there, you can try installing from the package manager.

I want to know how to install it using the pre-built binary as I have certain circumstances. I read the installation guide. After some tweaks, I found that in the file named
relocate-once.py
there was a problem in the declaration for the python env after I changed it topyhton3
it startedRewriting paths for your new installation directory
then it gave an error/home/my_pc/Downloads/SageMath/local/bin/python3: line 1: ./python3.7: No such file or directory
. I checked it the file exist but for some reason it doesn't execute it. That's where I'm stuck now. Aug 10, 2020 at 10:09 -

After the modification that I've mentioned, it gets stuck with the error
/home/my_pc/Downloads/SageMath/local/bin/python3: line 1: ./python3.7: No such file or directory
. When I went to the directory the filepython3
exist. It seems that the scriptpython
(which just has one execution command in it, i.e../python3.7
) has some trouble running. And it returns that error. Aug 10, 2020 at 14:40 -
I was able to install sage 9.2. With some modifications to the
relocate-once.py
file, where I had to change#!/usr/bin/env python
-->#!/usr/bin/env python3
for my system. I downloaded the tarball and after extraction followed the instructions in the installation guide file. P.S. I was not able to install sage 9.1 in ubuntu 20.04. So, I installed sage 9.0 that was available via ubuntu repositories. Apr 25, 2021 at 8:04
