When I start qgis with the terminal I get the following error:

No idea what is happening.

I had some problems in the installation, I had to create a fake gdal-abi-2-2-3 package and had to install grass-core_7.4.0-1_amd64 instead of grass-core_7.4.3 for dependency problems with Virtual package grass740.


I had no issue installing on 18.04 using the instructions at http://qgis.org.


deb https://qgis.org/debian bionic main # disabled on upgrade to bionic
deb-src https://qgis.org/debian bionic main # disabled on upgrade to bionic


sudo update
sudo upgrade
sudo apt-get install qgis python-qgis qgis-plugin-grass

and all was fine, including gdal and grass.

$ apt list gdal-*
Listing... Done
gdal-bin/bionic,bionic,now 2.2.3+dfsg-2 amd64 [installed]
gdal-data/bionic,bionic,bionic,bionic,now 2.2.3+dfsg-2 all [installed]
$ apt list grass 
Listing... Done
grass/bionic,bionic,bionic,bionic 7.4.0-1 all
$ apt list grass-core
Listing... Done
grass-core/bionic,bionic,now 7.4.0-1 amd64 [installed,automatic]
  • Yes, I first tried with these instructions, but I got the errors above commented. :( – R. Curcoll Jan 10 at 16:33
  • try apt purge grass qgis gdal before you start – Ian Turton Jan 10 at 16:41
