It's not working because gdal for trusty was just updated to 1.11.2 So I looked at the qgis package on my machine and it saying depends:libgdal.so.1-1.11.1 It struck me as odd that the qgis package specified a specific so version. Can someone look into this and fix it? libgdal.so.1-1.11.1 is a virtual package provided by libgdal1h of the same source package. The virtual package dependencies are added to ease transition tracking for packages that depend on the C++ symbols in libgdal.so. Every time a new minor version of gdal is uploaded all reverse dependencies that use on C++ symbols need to be rebuilt. The packages that rely on C++ symbols can be determined by their dependency on the libgdal.so.1-VERSION virtual package.

I don't remember having problems with using the dev version. It's stable. Probably and maybe I'm wrong, the main implications using the dev version is that some feature will be changed at some moment later.
