I tried the followings but the response did not change...
sudo apt-add-repository ppa:ubuntugis/ubuntugis-<wbr>unstable
sudo apt-get update
sudo apt-get install python-gdal
Any suggestions?
Thanks,

<pre>The warning says it all. You use GDALRasterBand::RasterIO() but do not
check
the return value. You probably don't get it on your local machine since it
might use an older version of GDAL where this method wasn't tagged with the
warn_unused_result attribute.
The right fix is to check the return value and do something appropriate.
Or you
can silence the warning by enclosing the calls in CPL_IGNORE_RET_VAL(...)
