Here's what I get: sudo apt-get remove libgdal20 [sudo] password for jimi: Reading package lists... Done Building dependency tree Reading state information... Done Package 'libgdal20' is not installed, so not removed
That was expected, because apt-cache policy libgdal20 already told you that it was not installed.

These are still GDAL 3.02 packages that you installed with the ubuntugis PPA. Get rid of those, otherwise you will not get further.
I'm still not clear about what the ubuntugis PPA is needed for, or what gdal even is..
GDAL is more or less the heartbeat of QGIS. Almost every operation uses it. For some reason, you must use exactly the same GDAL version as the QGIS package is compiled against. For bionic (without ubuntugis), this is GDAL 2.2.3. The gdal-abi package is used to confirm that version.
With the Ubuntugis PPA, you have installed a newer version of GDAL (3.0.2), and the packet manager does not downgrade it by itself (it does not know about th specific QGIS requirements).
