Installed sage 7.6 on Ubuntu 16.04 LTS to work with a colleague who is also on 7.X release (they are on Fedora). It all seemed to go OK but consistently get a crash message as soon as it starts. A crash report text file is created - can supply that for someone to look at.

Here is the terminal output:

┌────────────────────────────────────────────────────────────────────┐ │ SageMath version 7.6, Release Date: 2017-03-25 │ │ Type "notebook()" for the browser-based notebook interface. │ │ Type "help()" for help. │ └────────────────────────────────────────────────────────────────────┘


Oops, Sage crashed. We do our best to make it stable, but...

A crash report was automatically generated with the following information: - A verbatim copy of the crash traceback. - A copy of your input history during this session. - Data on your current Sage configuration.

It was left in the file named: '/home/davelautzenheiser/.sage/ipython-5.0.0/Sage_crash_report.txt' If you can email this file to the developers, the information in it will help them in understanding and correcting the problem.

You can mail it to: sage-support at sage-support@googlegroups.com with the subject 'Sage Crash Report'.

If you want to do it now, the following command will work (under Unix): mail -s 'Sage Crash Report' sage-support@googlegroups.com < /home/davelautzenheiser/.sage/ipython-5.0.0/Sage_crash_report.txt

We need mor information to understand what happened:

  • did you install Sage from the binaries, and which ones ?
  • did you compile Sage yourself ?
  • which error message did you get (crash report) ?
  • ... ?

Installation was from binaries - sage-7.6-Ubuntu_16.04-x86_64.tar.bz2 with target machine running Ubuntu 16.04 LTS.

Yes, a crash report was generated. Not sure how to upload the whole thing - 21KB Start of crash report has following:

If you do not have a presonal web page, you could use some pastebin service.

Discovered that gfortran was not installed. Now appears that Sage is working!
