QGIS goes Flatpak – a quick review with (k)ubuntu and Manjaro 18(KDE)

Although *buntu is in love with snaps (snapcraft) to deliver and update apps on any Linux distribution, it was time to have a look on the new QGIS 3.4 Flatpak package. And using Manjaro with a dated QGIS-version (and non-GRASS) in its repo, Flatpak is the quick solution.

Is the widely pushed OGC Geopackage (GPKG)(http://www.geopackage.org/) ready for daily use – also as a replacement for the good old Shapefile as an exchange-format ? While QGIS already supports Geopackage (including direct editing) quite well for some time, the format starts to grow up in the ESRI environment. Some good news with ArcGIS Pro 1.4 …
