Hi team,<br>
<br>
Well, this is a bit embarrassing. I've just started working with GIS data<br>
in Blender (BlenderGIS is a great add-on if anyone doesn't know it<br>
already). Anyway, I was trying to add a reference basemap to a Blender<br>
project with polygons in it and I got an error message telling me to<br>
install GDAL. I'm a total novice at both Blender and QGIS, so I read<br>
around and people recommending adding the GDAL PPA in QGIS directly. I did<br>
so following the Linux guidelines here:<br>
<a href="https://developers.planet.com/planetschool/gdal-qgis-installation-setup/" rel="noreferrer" target="_blank">https://developers.planet.com/planetschool/gdal-qgis-installation-setup/</a><br>

This is outdated by a few years. The current setup for QGIS can be found here:<br>
<br>
<<a href="https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu" rel="noreferrer" target="_blank">https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu</a>><br>
<br>
You have two choices: With or without the ubuntugis ppa.<br>
The ppa holds GDAL 3.0.2 along with all dependencies.<br>
Without the PPA, you can get GDAL 2.2.3<br>
<br>
QGIS supports both channels, using a different folder to download from.<br>

The following packages have unmet dependencies.<br>
qgis : Depends: gdal-abi-2-2-3<br>
</blockquote>
<br>
<br>
This seems to be the QGIS version without ubuntugis support.<br>
<br>
Try<br>
deb <a href="https://qgis.org/ubuntugis" rel="noreferrer" target="_blank">https://qgis.org/ubuntugis</a> bionic main<br>
<br>
and it should work.<br>
<br>
After re-installing, you should be able to install gdal-bin too.<br>
<br>
If you want (or must) to stick to GDAL 2, remove all ubuntugis references, and take QGIS from the ubuntu repo.You might need to remove GDAL 3 if you already installed it.<br>
