Thank you very much. I was unaware of the sage-support site.

SageMath: sage-9.1-Ubuntu_18.04-x86_64.tar.bz2

Hello all, I am trying to install sage 9.1, but I get this error after the ./configure

configure: notice: the following SPKGs did not find equivalent system packages: boost cbc freetype gp2c isl libsemigroups pari_elldata pari_galpol pari_nftables pari_seadata perl_cpan_polymake_prereq perl_term_readline_gnu python3
checking for the package system in use... conda
configure: hint: installing the following system packages is recommended and may avoid building some of the above SPKGs from source:
configure:   $ conda install boost-cpp coincbc freetype isl pari-galpol pari-seadata
configure: After installation, re-run configure using:
configure:   $ ./config.status --recheck && ./config.status

After installing those packages:

/opt/SageMath$ conda install -c conda-forge boost-cpp coincbc freetype isl pari-galpol pari-seadata

I still get the same error when I rerun ./configure. I tried running make to see what would happen, and I get this:

I am not sure what is wrong. I installed the dependency packages first as well.

I could not get libpython3.7-dev to install; the package does not seem available, but i could get the python 3.8 version.

Thank you for all the help

Hello all, I just recently installed Sage 9.1 from a tar folder. It initially said I successfully installed Sage 9.1. After I closed the terminal and launched sage, the new terminal says it is sage 9.0. I tried installing Sage 9.0 before, but it never complied since I did not have the FORTRAN. I am not sure if that is creating a conflict. I am using Linux Mint 19.3 as my OS. I am relatively new to sage, so I might be wrong about the installation. Thank you for the help.

Welcome to Sage 9.0!

Why is there a repeated failure of packages. I have python, gcc, perl,etc. Is there a way to check if I have the correct version of the dependencies, or is there something wrong with the packages.

Hello, @dsejas , I was recommended to install from scratch from the previous question I asked. Thank you for the help. https://ask.sagemath.org/question/499...

Sorry for the delay I added the log file

Hello, all I am attempting to install sagemath 9.0, but I am getting this error.

Commands imputed into the terminal:

 cd ~
 git clone github link for sage math # Note in my commands I did post the link, but I do not have enough karma points to post links in the sagemath fourms
 cd sage
 MAKE="make -j8" make 2>&1

Hello all, I am using Linux Mint 19.3 and installed SageMath 9.0 from the source. I am not sure what is going on , I even did the

sudo chown -R root:root ./SageMath

sudo ln -s /opt/SageMath/sage /usr/local/bin

sage

commands. I attached the error below. I apologize for the error being long, but I am not sure what any of this means. Thank you for all the 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:
    '/tmp/tmpockv4tsi/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 
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' 

In your email, please also include information about:
- The operating system under which the crash happened: Linux, macOS, Windows,
  other, and which exact version (for example: Ubuntu 16.04.3, macOS 10.13.2,
  Windows 10 Pro), and whether it is 32-bit or 64-bit;
- How Sage was installed: using pip or conda, from GitHub, as part of
  a Docker container, or other, providing more detail if possible;
- How to reproduce the crash: what exact sequence of instructions can one
  input to get the same crash? Ideally, find a minimal yet complete sequence
  of instructions that yields the crash.

To ensure accurate tracking of this issue, please file a report about it at:
