Details
This command upgrades the Juju agent for a controller.
A controller’s agent version can be shown with juju model-config -m controller agent-version.
A version is denoted by: major.minor.patch
You can upgrade the controller to a new patch version by specifying the ‘–agent-version’ flag. If not specified, the upgrade candidate will default to the most recent patch version matching the current major and minor version. Upgrading to a new major or minor version is not supported.
The command will abort if an upgrade is in progress. It will also abort if a previous upgrade was not fully completed (e.g.: if one of the controllers in a high availability model failed to upgrade).
