1) package is 'juju-2.0' yet binary is not there anymore. One of these should change.

2) command-not-found needs updating?

3) Maybe introdce a 'juju-2' link?

So we have to make a decision on how we're going to treat 2.x releases. We can swap all of these things to ensure juju 2.1 works in this scenarios. We can also ensure you either can or cannot install them alongside either other. Do we need a generic juju-2 symlink?

Either way, the work here is to improve debian/rules to respect $VERSION.

[David Britton (dpb)]

For backward compatability reasons, please at least keep the juju-2.0 symlink working. It's in xenial already.

[Nicholas Skaggs (nskaggs)]

Our packaging is currently "juju-2.0_2.1~beta3-0ubuntu1~12.04.1~juju1_amd64.deb"...

I think we agree now we'd like to see this:

dpb@helo:~[0]$ ll /usr/bin/juju-[0-9]*
lrwxrwxrwx 1 root root 9 Aug 16 14:04 /usr/bin/juju-1 -> juju-1.25*
-rwxr-xr-x 1 root root 68 Aug 16 14:04 /usr/bin/juju-1.25*
lrwxrwxrwx 1 root root 9 Aug 16 14:04 /usr/bin/juju-2 -> juju-2.1*
-rwxr-xr-x 1 root root 67 Nov 17 09:40 /usr/bin/juju-2.1*

[Nicholas Skaggs (nskaggs)]

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

No changes to the overall package name so nothing to fix for landscape. Txjuju already searches the path for juju-2 juju-2.0 juju-2.1 in that order to we are insulated from 2.X minor releases.
