[Qgis-user] Install QGIS 3.x on Ubuntu16.04

[Andre Joost]

Hi,

you get stuck because qgis 3.4.6 from qgis.org is built against GRASS 
7.6.0 from the ubuntugis-unstable ppa, but that ppa has upgraded to 
Grass 7.6.1 in the meantime.

This should be resolved by the next QGIS point release.

Alternatively, you can remove the qgis.org stuff from your sources list, 
purge and autoremove the 3.4.4 packages, and install QGIS 3.4.6 from the 
ubuntugis-unstable ppa only.

HTH,
Andre Joost
