Bonjour
J'ai aussi un problème un peu identique
Je suis sous ubuntu 18.04.5 LTS
J'ai voulu installer la dernière version de QGIS à savoir la 3.16 après avoir désinstallé la version précédente.
Je suis passé par le terminal en utilisant du code trouvé sur internet. J'ai dû bien me mélanger les pinceaux car je suis complètement bloqué.
Dès le départ le code suivant : <sudo apt install gnupg software-properties-common> me renvoie ceci < E: Le type « wget » est inconnu sur la ligne 1 dans la liste des sources /etc/apt/sources.list
E: La liste des sources ne peut être lue.>
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
