I was trying to install SageMathCell on a VPS with Ubuntu 16.04.2 LTS (GNU/Linux 2.6.32-042stab120.20 x86_64) following the instructions form the oficial GitHub repository page on https://github.com/sagemath/sagecell . In the section "Simple Installation" on the step 3 after the "make" command, and after waiting a log time for building, an error occurs , displaying the following on the terminal.
