How to install Sage on Google Colab?

[demining]

I am trying to install "Sage" on Google Colab via the command:

!pip install git+https://github.com/sagemath/sage.git

I get the error:

Collecting git+https://github.com/sagemath/sage.git
  Cloning https://github.com/sagemath/sage.git to /tmp/pip-req-build-ozlqhlkb
  Running command git clone -q https://github.com/sagemath/sage.git /tmp/pip-req-build-ozlqhlkb
ERROR: File "setup.py" not found for legacy project git+https://github.com/sagemath/sage.git.

No module named 'sage.all_cmdline'

Traceback (most recent call last):
  File "script.py", line 11, in <module>
    from sage.all_cmdline import *   
ModuleNotFoundError: No module named 'sage.all_cmdline'

Google Colab works on
Description: Ubuntu 18.04.5 LTS
Codename: bionic
model name: AMD EPYC 7B12

pip3 --version
pip 21.1.3 from /usr/local/lib/python3.7/dist-packages/pip (python 3.7)

Why can't I install "Sage" ? What could be the reasons for this error?

This is not the place to ask sage related questions. For that please use https://ask.sagemath.org/

Additionally according to the installation guide https://doc.sagemath.org/html/en/installation/ the recommended way of installing sage on ubuntu is using ubuntu's package manger and not pip.

@koffie Please tell me what command you need to set to install all packages "Sage"
Unfortunately, I can not post a question on the site ask.sagemath.org/questions/ask/ because from the moment of registration I have a notification: "Could not post, because your karma is insufficient to publish links

Well just google ubuntu install sagemath and you get a lot of useful hits like https://askubuntu.com/a/1159008/1033768 where they explain you should do something like

sudo apt-get install sagemath

Needing to point someone who whas linux as part of their username and Tux as their avatar to apt-get feels a bit awkward.

In addition to ask.sagemath.org, there are also the Google groups on Sage.

@sberlinux -- making Sage pip-installable is work in progress, tracked at

• Sage Trac ticket 29705

I have not heard of Sage running on Google Colab so far.
You might want to give CoCalc a try, as Sage works fine there.

New Ask Sage users cannot post links but can add spaces
to disguise them, eg by typing https ://ask .sagemath .org.
