J'essaie d'installer l'unité-webapps-preview, alors j'ai déjà ajouté le PPA:
$ Sudo add-apt-repository ppa:webapps/preview
$ Sudo apt-get update
mais j'obtiens l'erreur suivante:
$ Sudo apt-get install unity-webapps-preview

xul-ext-webaccounts : Breaks: firefox (>= 14.+) but 15.0.1+build1-0ubuntu0.12.04.1 is to be installed

Version de Firefox: 15.0.1
Version de Ubuntu: 12.04
Vous ne pouvez pas l'installer car le paquet actuel unity-webapps-preview dépend de Firefox 14 pour une raison quelconque (même s'il fonctionne très bien avec les versions 15 et plus récentes), vous devrez donc attendre une mise à jour pour pouvoir l'installer. .
Piotrek Sobieszczański dans un autre forum a déclaré: "Supprimez simplement l'aperçu de la fin du nom du paquet ..$ Sudo apt-get install unity-webapps
". Cela a fonctionné pour moi.
