python - Installing GDAL2.1

Here will be my sequence of command lines while trying to install gdal2.1 in a UBUNTU virtual machine. My virtual machine is a UBUNTU 16.04 LTS(64bit) I would need gdal2.1 and especially the Python bindings to work with it in python. The versionof python currently working is 2.7.11+ and I installed numpy as I know that it is necessary for GDAL. now the command lines with the instruction I found in the Pypi page of GDAL2.1:

This was what I obtained. Consider that the VM has not other software or packages installed. I hope you can help me, using GDAL2.1 would be so important..
