I am trying to use GDAL_Rasterize and found a link via Google that suggested that there were bugs in older versions.

I am running Ubuntu 14.04 LTS and 'gdalinfo --version' gives me 'GDAL 1.11.2, released 2015/02/10'

When I try 'sudo apt-get install python-gdal' I get the following:

Reading package lists... Done

Reading state information... Done python-gdal is already the newest version. The following packages were automatically installed and are no longer required: libqgis-analysis2.14.2 libqgis-analysis2.8.1 libqgis-app2.14.2 libqgis-core2.14.2 libqgis-core2.8.1 libqgis-gui2.14.2 libqgis-gui2.8.1 libqgis-networkanalysis2.14.2 libqgis-networkanalysis2.8.1 libqgis-server2.14.2 libqgis-server2.8.1 libqgisgrass2.8.1 libqgisgrass6-2.14.2 libqgispython2.14.2 libqgispython2.8.1 libsaga-api-2.2.6 libsaga-gdi-2.2.6 Use 'apt-get autoremove' to remove them. 0 to upgrade, 0 to newly install, 0 to remove and 9 not to upgrade.

Is there an easy fix for this?


I tried the fix at Installing gdal 1.9.0 on linux ubuntu server 10.04?

I editied it to look for the new release: wget ftp://ftp.remotesensing.org/gdal/CURRENT/gdal-2.1.0.tar.gz tar xvfz gdal-2.1.0.tar.gz cd gdal-2.1.0 ./configure --with-python make sudo make install

Now GDAL won't load at all. More worryingly Qgiswon't load either:


Couldn't load plugin 'processing'

You have installed QGIS with ubuntugis support. https://launchpad.net/~ubuntugis/+archive/ubuntu/ubuntugis-unstable/+packages?field.name_filter=&field.status_filter=published&field.series_filter=trusty reveals that they only have GDAL 1.11.2 for trusty. The ubuntugis stable ppa does not offer a newer version for trusty either.

They offer however GDAL 2.1.0 for Ubuntu Xenial. So my best bet is to upgrade the operating system. GDAL is seldomly backported to older versions of Ubuntu.

Installing GDAL from a different source leads to unwanted trouble, if your version of QGIS is not compiled for that GDAL version. And I guess you don't want to compile QGIS from source to overcome that.

    Good answer, how do I back out of this? – SteveResearch Jun 8 '16 at 16:10
  • Switch to Xenial. You might test it in a virtual box, until you are satisfied. You can exchange data between both systems with shared folders. – AndreJ Jun 8 '16 at 17:50
  • I am not sure how that helps me back out to a working installation of Qgis and GDAL? – SteveResearch Jun 8 '16 at 21:20
  • You can install QGIS and GDAL inside the virtual box. They don't know about the broken installation on the host system. – AndreJ Jun 11 '16 at 7:27
  • @AndreJ - That is no longer true. GDAL 2.1 is now available for ubuntu 14.04 from ubuntugis-unstable – Will. Aug 4 '16 at 19:10
