En essayant d'installer libsdl2-dev Je reçois ça :
The following packages have unmet dependencies.
libsdl2-dev : Depends: libegl1-mesa-dev but it is not going to be installed
Depends: libgl1-mesa-dev but it is not going to be installed
Depends: libgles2-mesa-dev but it is not going to be installed
Depends: libglu1-mesa-dev but it is not going to be installed
E: Unable to correct problems, you have held broken packages.J'ai mis à jour une nouvelle installation à partir de xenial et j'ai rencontré ces problèmes.
J'ai fait comme d'habitude, apt-get dist-upgrade nettoyer, mais pas de chance. Lorsque je commence à ajouter les paquets supplémentaires mentionnés, j'ai l'impression de m'enfoncer dans un trou de lapin en ajoutant éternellement des paquets supplémentaires à installer.
Voici la sortie de l'application cd /etc/apt&&find -name \*list -exec egrep -vH "^#|^$" {} \; Comme demandé, j'ai dû modifier en supprimant l'option http:// de la sortie comme ne permettant pas plus de 2 liens.
