If you fail to install GDAL on Debian, follow the procedure:
Install dev tools:
sudo apt-get install libgdal-dev

export C_INCLUDE_PATH=/usr/include/gdal
Check which version of GDAL was installed:
gdalinfo --version
Use the same version (x.x.x) to install GDAL as a Python package:
pip install GDAL==x.x.x
