Packer: Fail to go get

[yukihiko-shinoda]

Overview of the Issue

Until yesterday (2020-11-20), I could go get github.com/hashicorp/packer.
Today (2020-11-21), I can't go get github.com/hashicorp/packer.
It looks required to develop packer plugin:

cf. Plugins - Extending | Packer by HashiCorp

Or, do I mistake something to prepare develop environment for packer plugin?
(I'm quite new to develop it...)

Reproduction Steps

1.
Create Dockerfile:

FROM golang
RUN go get github.com/hashicorp/packer

2.
Run build:

docker build .

Packer version

master branch

Hello there ! Thanks for opening, I fixed this in #10296. You probably know what you are doing but using a tagged version of packer could have helped you here. 🙂 for example: go get github.com/hashicorp/[email protected]
