Schémas manquants - Unity Tweak Tool
Je comprends que cela ressemble beaucoup à cette question et celle-ci , mais aucune des réponses n’a fonctionné pour moi. En essayant d'installer les paquets mentionnés dans ces questions, apt-get génère le message d'erreur suivant:
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.
unity-webapps-service : Depends: webapp-container
E: Unable to correct problems, you have held broken packages.
Lorsque j'essaie d'installer les dépendances mentionnées ici, je trouve simplement de plus en plus de dépendances. Le gestionnaire de paquets Synaptic affiche des messages d'erreur lorsque je sélectionne 'Réparer les paquets endommagés'. Comment puis-je réparer cela?
Merci d'avance, et s'il vous plaît commenter si vous avez besoin de plus d'informations.

The following information may help to resolve the situation:
The following packages have unmet dependencies.
webapp-container : Depends: qtdeclarative-abi-5-2-1
Depends: unity-webapps-qml but it is not going to be installed
Depends: webbrowser-app (= 0.23+14.04.20140428-0ubuntu1)

Je vais le risquer et laisser une réponse.
Un problème principal semble être le PPA PPA: mscore-ubuntu/mscore-stable. Avec ce PPA, vous ne pouvez pas utiliser la version nécessaire de libqt5qml5
Par conséquent, supprimez le PPA avec la commande suivante.
Sudo ppa-purge ppa:mscore-ubuntu/mscore-stable
Après ça
Sudo apt-get install -f
et enfin
Sudo apt-get install unity-webapps-service
Où est le problème?
La commande apt-cache policy libqt5qml5 renvoie ce qui suit. Le PPA PPA: mscore-ubuntu/mscore-stable installe une version plus récente (5.3.0) pour libqt5qml5 mais qtdeclarative-abi-5-2-1 a besoin de la version exacte 5.2.1.
libqt5qml5:
