operating system is Ubuntu 18.04.3 LTS
O.S type is 64 bit.
steps:
1. downloaded sage-8.9-Ubuntu_18.04-x86_64.tar.bz2 package.
2. extract using
tar xvf sage-8.9-Ubuntu_18.04-x86_64.tar.bz2
3. cd Sagemath
4. ./sage
Note: Attached sage crash report that has been generated when i run ./sage.
i is working fine when i use sudo ./sage
