To whom it may concern,

 I'm installing sage from the synaptic package manager on Linux Mint 20.1. The package is for Sage 9.0, but the app does not run. Following is the crash report, any advice on how to best resolve (uninstall and install from source?) is appreciated:

This has to be reported to Linux Mint - we don't do packaging for
particular Linux distributions, and it looks like a packaging error,
not anything we can help with.
You can install Sage in several other ways:

The package log has the following error:

I think there is something about the way sage is trying to be installed and python, but I'm unsure how to diagnose. Installing from source is an option yes, but I fear it will have the same issue.

I think the issue is a disagreement with python. The package installs fine on a clean machine. I know this isn't the wheelhouse, but how can I diagnose my python configuration for compatibility with sage. In particular, I have python 3.8.10 installed systemwide.

On my system, python2 and python3 is installed, but there is no generic python symlink. Does this need to be created for sage and if so should it be python3? In installed from tarball, so this is not an issue with the Ubuntu package.

The latest binary for Linux (https://www.sagemath.org/download.html) is Sage 9.3. If you are using this binary tarball, you will have to make sure that the symlink python->python3 exists; there is a package that provides it. See also https://wiki.sagemath.org/ReleaseTours/sage-9.3#Availability_in_distributions_and_as_binaries

The latest version is Sage 9.4. Using the source tarball, there is no need to do anything about python/python3. Just follow the instructions in the README.

So I got this working in my home directory but want the SageMath directory system wide. I moved it to /opt and changed ownership to root.root, however this causes now a disagreement with the SAGE_ROOT environment variable. Should I unpack the tarball as root there to install or is there an easy config/make that I can run on this directory to get it to work as a system wide install?

As the directory is in /opt and ownership is root.root, I can't run this as it gets permission denied when writing the log file.

I can ask this another way. I have the tarball, and I want to end up with a system wide install. This is not build from source. What is the best way to do this?

In the referenced instructions the modification is to SAGE_LOCAL and not SAGE_ROOT. I'm confused as to the difference and effect.
