Je n'arrive pas à récupérer du contenu sur le web en utilisant `curl. J'ai essayé de l'installer et j'ai obtenu le résultat ci-dessous :
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies.
curl : Depends: libcurl4 (= 7.58.0-2ubuntu3) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
J'ai vérifié la présence de paquets maintenus à la fois avec sudo apt-mark showheld
y dpkg -l | grep ^h
mais je n'obtiens aucun résultat.
De plus, lorsque j'essaie d'installer libcurl4
Il a presque cassé mon système, puisqu'il tente de supprimer ces paquets :
