Hello tout le monde.
Je viens de découvrir la June et je tente de rejoindre le mouvement, mieux vaut tard que jamais 
J’ai choisi d’installer Cesium sur mon Ubuntu 20.04.2 LTS en 64 bits mais souci : que je lance Cesium Ĝ1 ou Cesium Ĝ1-Test, je vois une petite fenêtre de chargement puis plus rien.
En ligne de commande, j’ai la même erreur :
thibaut@tiportable:~$ cesium-g1-test

J’ai bien entendu tenté d’installer libgconf-2-4 :
thibaut@tiportable:~$ sudo apt-get install -y libgconf-2-4
[sudo] password for thibaut:
Reading package lists... Done
Building dependency tree
Reading state information... Done
libgconf-2-4 is already the newest version (3.2.6-6ubuntu1).
0 to upgrade, 0 to newly install, 0 to remove and 6 not to upgrade.
Que puis-je faire du coup ? Merci pour l’aide. Je précise que je n’ai pas installé d’autres versions de Cesium (extensions navigateur), le bug viendrait de là ?
Merci
