Bonjour,

Avez-vous bien le fichier ".pkg” sur le Bureau (Desktop en anglais) ?
Si oui, êtes-vous bien sûr le bureau dans le terminal ? ("cd Desktop” normalement il affiche "desktop” à gauche de ou vous écrivez.)

Pour être sûr, vous pouvez taper la commande "ls -al", ça affiche une liste et vous pouvez voir s'il y a bien le fichier dans cette liste. S'il n'y est pas, vous n'êtes pas au bon endroit.
