J'essaye de faire le minikube delete comme conseillé.

Encore un problème de permissions… C'est quoi les permissions sur ce dossier ?

Résolution et lancement de minikube
Les permissions étaient en root partout ! C'est pour ça que ça coinçait !
$ sudo chown -R simon:simon /home/simon/.minikube/ $ minikube start Starting local Kubernetes v1.10.0 cluster... Starting VM... Getting VM IP address... Moving files into cluster... Setting up certs... Connecting to cluster... Setting up kubeconfig... Starting cluster components... Kubectl is now configured to use the cluster. Loading cached images from config file.
Yes! Minikube est lancé !
