I think it still compiles against 1.11, doesn't it ? Ubuntu 16.04 still ships with 1.11, will the ubuntu packages require ubuntugis that has 2.1 ?

True, but I think we also had a discussion about making GDAL 2.0 mandatory for QGIS 3.
I don't remember the exact reasoning. What do you think, is there any advantage of marking it required?

Dropping 1.X support would simplify the code, but we should check that this doesn't cause packaging headaches. The Ubuntu packages don't require UbuntuGIS, do they ? Being able to provide support for 16.04 is IMHO a plus.

Is there no "must-have" functionality in GDAL 2 (e.g. geopackage related)?

I think the timeline for 3.0 is post 17.04 (which I hope ships GDAL 2) and personally I don't mind taking the opportunity to do some cleanups if it means making ubuntugis a required dependency for older distros. But certainly only if there's a good reason for it.

Yes support for GeoPackage in 2.0 is far more complete than in 1.11 (raster + spatial index for vector). And for full support with QGIS DbManager (table renaming and addition, renaming fields, etc..) you need 2.1.2 actually.

I think the timeline for 3.0 is post 17.04 (which I hope ships GDAL 2)

2.1.2 according to https://launchpad.net/ubuntu/+source/gdal

Who is our Debian/Ubuntu package master : @jef ? Any opinion ?
