Entfernen Sie die in apt-cache aufgeführten gdal-Pakete

Bei einer fehlerhaften Installation kann gdalich das sf RPaket nicht in meiner Standardumgebung installieren conda(siehe https://stackoverflow.com/a/51369036/1840471 ). Ich versuche alle Nicht-Conda- gdalPakete zu entfernen, habe aber Schwierigkeiten.

Ich habe diese Befehle bereits ausgeführt:

sudo pip freeze | xargs pip uninstall -y # To remove all pip packages. sudo apt-get purge gdal-bin sudo apt-get purge build-essential python-all-dev sudo apt-get purge libgdal-dev sudo apt-get purge libproj-dev # Per https://gis.stackexchange.com/a/179458/65604 sudo ln -s /usr/lib/libproj.so.0 /usr/lib/libproj.so 

Aber das apt-cache search gdalzeigt immer noch:

Wie kann ich alle apt-get gdalzugehörigen Pakete entfernen ?
