Upgrade `juju`

See also: Upgrading things, juju (the Juju CLI client)

This document demonstrates how to upgrade juju.

Ensure you’ve created a backup of your ./local/share/juju before starting the upgrade process for the client. See How to back up juju.

If the Juju client was installed via snap, the updates to the client should be handled automatically. You can see the latest version of the installed snap by calling snap info juju.

If there has been a new release but the juju snap hasn’t been refreshed, you can manually trigger this with sudo snap refresh juju.

Moving from one channel to another can be done using the --channel argument.

For some channels, e.g., 2.9, one must also attach the --classic flag. See snap help refresh for what this flag and others mean.

sudo snap refresh --channel=2.9 --classic juju
