Here is what I get:
/opt/sagemath-9.3/sage: /opt/sagemath-9.3/src/bin/sage: /usr/bin/env: bad interpreter: No such file or directory /opt/sagemath-9.3/sage: line 139: /opt/sagemath-9.3/src/bin/sage: No error /bin/bask: Exit 126.
I have tried re-installing Sage, but to no avail.
Any help would be appreciated.
