Afin de progresser dans mon problème j'ai donc lancé la requête suivante : sudo gedit /etc/apt/sources.list
Ce qui me donne ceci :
wget -O -
https://qgis.org/downloads/qgis-2020.gpg.key | gpg --import
wget -O -
https://qgis.org/downloads/qgis-2017.gpg.key | gpg --import
gpg --fingerprint CAEB3DC3BDF7FB45
O
gpg --export --armor CAEB3DC3BDF7FB45 | sudo apt-key add -
sudo apt-get update
sudo apt-get install qgis python-qgis qgis-plugin-grass
