Some sort of mess I have made by not properly cleaning resources under juju, so after that any other command but "juju controllers" would stuck and not responding.
How to delete those rather non existing controllers from the list reported?
$ juju controllers Use --refresh option with this command to see the latest information. Controller Model User Access Cloud/Region Models Nodes HA Version alter-ego default admin superuser localhost/localhost 1 1 none 2.9-beta1 osm-k8s osm admin superuser microk8s/localhost 2 - - 2.9-beta1 osm-lxd* default admin superuser localhost/localhost 2 1 none 2.8.0
juju destroy-controller --help
This can be a good start. It gives you additional options like:
--destroy-all-models
and
--destroy-storage or --release-storage
Examples: # Уничтожить контроллер и все размещенные модели. Если есть # постоянное хранилище, оставшееся в любой из моделей, затем # это побудит вас выбрать либо уничтожить, либо отпустить # хранение. juju destroy-controller --destroy-all-models mycontroller
# Destroy the controller and all hosted models, destroying
# any remaining persistent storage.
juju destroy-controller --destroy-all-models --destroy-storage
# Destroy the controller and all hosted models, releasing
# any remaining persistent storage from Juju's control.
juju destroy-controller --destroy-all-models --release-storage
