This is outdated by a few years. The current setup for QGIS can be found 
here:

<https://www.qgis.org/en/site/forusers/alldownloads.html#debian-ubuntu>

You have two choices: With or without the ubuntugis ppa.
The ppa holds GDAL 3.0.2 along with all dependencies.
Without the PPA, you can get GDAL 2.2.3

QGIS supports both channels, using a different folder to download from.

This seems to be the QGIS version without ubuntugis support.

Try
deb https://qgis.org/ubuntugis bionic main

and it should work.

After re-installing, you should be able to install gdal-bin too.

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.

HTH,
