Packer: panic: interface conversion: interface {} is Config, not *Config

[azr]

We recently merged a fix for this but it should show something like this:

This bug was fixed in #8513

It happens in the following builders :

• cloudstack
• hyperv/iso
• hyperv/vmcx
• linode
• lxc
• lxd
• oneandone
• oracle/classic
• oracle/oci
• osc/bsuvolume
• parallels/pvm
• profitbricks
• scaleway
• vagrant
• virtualbox/ovf

The nightly build of packer contains the fix: https://github.com/hashicorp/packer/releases/tag/nightly

[SwampDragons]

This affects enough builders that today I'll be pushing a fast-follow 1.5.1 release with the fix.

Closed by the 1.5.1 release.
