How do I save a file in QGIS as .gpkg?
I wish to use this file format because it supports column names larger than 10 characters.

I'm seeing this years later, but if someone still wonders...
In addition to the "save as" method, with QGIS 3.0, you can click and drag layers inside a GeoPackage within the Browser panel.
I had no problem with saving selected features as a new layer into an existing GeoPackage with QGIS 3.18. Just give the name for the new layer and QGIS does not even ask further questions.
If user selects an existing layer for output then a new window opens. If the aim was to create a new layer user must cancel and change the layer name in the previous window.
It is also possible to add new layers into an existing GeoPackage from command line with ogr2ogr. The command would look like
ogr2ogr -f GPKG -update -append existing_geopackage.gpkg data_to_add.shp

In the current version (2.12.2) it is possible to save a layer as Geopackage (right-click on layer--> Save As...).
