Public bug reported: When upgrading to Xenial the new default Juju version is going to be 2.0.
Because 2.0 clients are not compatible with 1.X environments, this means existing environments will be inaccessible unless the 1.X client is switched to. The plan is to give a warning when creating Juju 2 configuration for the first time, something along the lines of: $ sudo apt-get update $ juju status WARNING Creating new juju 2 configuration. Use `update-alternatives --config juju` to switch for 1.X environments. $ juju status ERROR Unable to connect to model "". Please check your credentials or use 'juju bootstrap' to create a new model. There has been some concern that this is still too confusing and 1.X should remain the default juju without explicit user intervention. ** Affects: juju-core (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to juju-core in Ubuntu. https://bugs.launchpad.net/bugs/1564670 Title: After upgrade Juju 1.X should still be the default To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/juju-core/+bug/1564670/+subscriptions -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
