Okular ne peut pas lire les fichiers pdf

J'ai récemment installé Okular sur mon Ubuntu 14.04.

Le problème, c’est que lorsque j’ouvre les fichiers pdf, okular me donne l’erreur "Vous ne trouvez pas de plug-in capable de gérer le document transmis".

Lorsque j'ai exécuté Okular par Terminal, voici le message que je reçois.

C'était assez ennuyant, mais:

Sudo apt-get install kdelibs5-plugins kdelibs5-data oxygen-icon-theme

J'ai eu le même message d'erreur. Dans mon cas, Okular était installé avec Sudo et les dépendances KDE étaient installées dans le dossier de base sous .kde, mais avec root en tant que propriétaire et groupe.

J'ai changé en cours d'exécution:

Sudo chown -R youruser .kde    
Sudo chgrp -R youruser .kde

alors cela a fonctionné normalement.

Selon les notes de publication de Linux mint, rubrique "Problèmes liés aux applications KDE".

Si vous rencontrez des problèmes avec les applications KDE (Okular, Gwenview, KStars..etc), exécutez la commande suivante:

apt install kdelibs-bin kdelibs5-data kdelibs5-plugins

Remarque: ces problèmes n'affectent pas l'édition KDE. Une régression dans KDE 4.14 empêche ces applications de fonctionner correctement en dehors de KDE.

Ouvrez le gestionnaire de paquets Synaptic et recherchez kde-core-devel

Installez tous les packages sous la version 4:4.14.2-0ubuntu1~ubuntu14.04~ppa1. Recherchez ensuite oxygen et installez le thème icône Oxygène.
