Dear my friend, I do the installation under your help. I reinstalled the sagemath software with the steps: 1. download the latest version of SageMath 8.7 for Linux Ubuntu 18.04, and *mv sage-8.7-Ubuntu_18.04-x86_64.tar.bz2 /usr/local/* 2. Reinstall WSL Ubuntu 18.04 3. *mkdir /usr/local/SageMath && chown -R newton /usr/local/SageMath* 4. *cd /usr/local/ tar xjvf sage-8.7-Ubuntu_18.04-x86_64.tar.bz2* *5. chown -R newton /usr/local/SageMath*
*6. cd SageMath/ && ./sage* *7. chown -R newton /usr/local/SageMath* *8. alias sage='/usr/local/SageMath/sage'* when I type sage in terminal with normal user*,* sage can be used. But there is still a warning: newton@Newton-PC-4:~$ sage ┌────────────────────────────────────────────────────────────────────┐ │ SageMath version 8.7, Release Date: 2019-03-23 │ │ Using Python 2.7.15.
