packer >= 0.9.0 compatibility

[dsbaars]

core: Plugins that implement the Communicator interface must now implement a DownloadDir method [GH-2618]
source: https://github.com/mitchellh/packer/blob/master/CHANGELOG.md

I don't have any experience with go yet, otherwise I'd try to fix it myself. I was hoping this will be useful for LXC 2.0 container creation

$ gox -os=linux -arch=amd64 -output=pkg/{{.OS}}_{{.Arch}}/packer-builder-lxc

Thanks for reporting!

I Haven't tried LXC 2.0 yet, so I can't tell you if it will work. If the commands didn't change much, there's a possibility :)

This affects me too. Any news?

I'm having the same issue, but before I even have the repo:
go get github.com/ustream/packer-builder-lxc

# github.com/ustream/packer-builder-lxc/builder/lxc
src/github.com/ustream/packer-builder-lxc/builder/lxc/builder.go:69: cannot use common.MultistepDebugFn(ui) (type "github.com/mitchellh/packer/vendor/github.com/mitchellh/multistep".DebugPauseFn) as type "github.com/mitchellh/multistep".DebugPauseFn in field value

	*LxcAttachCommunicator does not implement "github.com/mitchellh/packer/packer".Communicator (missing DownloadDir method)

I'm using go-1.8 through a ppa on ubuntu 16.04 since 1.6 did not get the packer-builder-lxc repository with go get.
I don't think it's due to LXC version:

LXC 2.0 is fully API compatible with LXC 1.0.

Seems to be an issue in mitchellh/multistep, but not sure, any advice?

edit
Going back to 1.6 yelds
