Comment installer Pantheon Desktop sur Ubuntu 15.04?

Oui, aucune des autres solutions de Comment installer l'environnement de bureau Pantheon? pour les anciennes versions d'Ubuntu a fonctionné. Le seul ppa qui ne disait pas "404 non trouvé" lors de la mise à jour était le ppa: elementary-os/daily, mais je ne pouvais pas installer elementary-desktop, car il venait juste d'être dit (dans la console) qu'il n'installe pas de paquet lié avec elle.

The following packages have unmet dependencies:
 elementary-desktop : Depends: ubuntu-extras-keyring but it is not installed
                      Recommends: apport-hooks-elementary but it is not going to be installed

J'ai réussi à installer le bureau élémentaire en reconstruisant localement ubuntu-extras-keyring sur mon système, comme ceci:

mkdir somedir; cd somedir
Sudo apt-get install -y debhelper
wget http://archive.ubuntu.com/ubuntu/pool/main/u/ubuntu-extras-keyring/ubuntu-extras-keyring_2010.09.27.{tar.gz,dsc}
tar -xf *.tar.gz
cd ubuntu-extras-keyring-2010.09.17
debuild -i -us -uc -b
Sudo dpkg -i ../ubuntu-extras-keyring_2010.09.27_all.deb

Après cela, elementary-desktop sera installé, mais comportera une erreur à la fin car cela dépend de systemd-shim qui n'est plus nécessaire ni souhaité avec 15.04 ayant une implémentation complète de SystemD.

Quand il tombe en panne, lancez

Sudo dpkg --force-depends -r indicator-datetime
Sudo apt-get purge unity-control-center unity-control-center-signon

et il devrait terminer l'installation.

Je m'attends à ce que les membres de l'élémentaire corrigent leur dépôt pour gérer correctement SystemD: Ubuntu 15.04 a été transféré à SystemD quelques semaines avant la sortie officielle et les membres de l'élémentaire n'ont probablement pas eu le temps de s'y adapter.

Après l’installation, vous pouvez vous déconnecter et voir "Panthéon" dans la liste des sessions de votre gestionnaire d’affichage, mais si vous essayez de vous connecter, vous n’obtiendrez que le papier peint Blueprint Elementary appelé "papier peint bêta". Le problème est que la session démarre Slingshot et Gala, mais pas WingPanel ou Plank. J'utilise actuellement le raccourci ALT-F2 de Slingshot pour ouvrir le programme de lancement et exécuter Plank et WingPanel manuellement (il vous suffit de taper le nom en minuscule et d'appuyer sur Entrée).
