Installing Juju development releases

The Juju core development team makes regular beta, release candidate and point releases. We encourage widespread testing of development releases and appreciate your feedback! It is of course best to use stable releases for production deployments.

Linux

We use semantic channels in the snap, so you can get edge, beta or candidate releases as well as the stable releases you need for production. To see the full channel map:

$ snap info juju
channels:
  latest/stable:    2.8.6              2020-10-30 (14498) 72MB classic
  latest/candidate: 2.9-rc1            2020-10-30 (14502) 97MB classic
  latest/beta:      ↑                                          
  latest/edge:      2.9-rc2-210f66c    2020-10-31 (14506) 97MB classic
  2.9/stable:       –                                          
  2.9/candidate:    2.9-rc1            2020-10-30 (14502) 97MB classic
  2.9/beta:         ↑                                          
  2.9/edge:         ↑                                          
  2.8/stable:       2.8.6              2020-10-30 (14498) 72MB classic
  ...

You can select a particular version, or get the latest version. Install with an explicit channel to make sure you get the version you want, for example:

sudo snap install juju --classic --channel=2.9/stable

On a true spare development system that is only used with development or test infrastructure, for example, you might choose:

sudo snap install juju --classic --channel=latest/beta

Other platforms

All development release binaries are published on Launchpad.
