juju 2.1 binary changed names, not sure the reasoning

[David Britton]

What is installed:

ii juju-2.0 1:2.1~beta3-0ubuntu1~16.04.1~juju1

/usr/bin/juju -> ../lib/juju-2.1/bin/juju*
/usr/bin/juju-2.1*
/usr/bin/jujud -> ../lib/juju-2.1/bin/jujud*

What failed:

Failure: txjuju.errors.CLIError: juju ended with exit code 1 (out='', err='Upon execvpe juju-2.0 ['juju-2.0', 'bootstrap', '-v', '--no-gui', '--to', 'bierstadt', '--auto-upgrade=fal se', '--config', '/var/lib/landscape/juju-homes/1/bootstrap.yaml', 'landscape-maas', '1'] in environment id 140155302643424

')

What I expected:

/usr/bin/juju-2.0 should be a binary that is maintained (at least a symlink).

/usr/bin/juju-2 should also be a symlink that is maintained.

This seems to be related to https://bugs.launchpad.net/juju-release-tools/+bug/1646223/

Indeed, follow bug 1646223 and please comment. We should nail this down for rc1. I envision a symlink for juju-2, with a versioned binary.

[Nicholas Skaggs (nskaggs)]

The symlink for juju-2 will be maintained. Try 2.1-beta5 packaging and see if this squashes these issues.
