Failed to build hadolint locally on Ubuntu 20.04.

[hongyi-zhao]

On Ubuntu 2.04, I try to build hadolint from the latest git master source code locally as shown below:

$ sudo apt-get install haskell-platform
$ curl -x socks5://127.0.0.1:18888 -fsSL https://get.haskellstack.org/ | all_proxy=socks5h://127.0.0.1:18888 sh -s - -f

$ git clone https://github.com/hadolint/hadolint.git hadolint/hadolint.git
$ cd hadolint/hadolint.git/
$ stack install
Exception while reading snapshot from https://raw.githubusercontent.com/commercialhaskell/stackage-snapshots/master/lts/16/18.yaml:

  port                 = 443

  requestHeaders       = [("User-Agent","Haskell pantry package")]
  path                 = "/commercialhaskell/stackage-snapshots/master/lts/16/18.yaml"
  queryString          = ""
  method               = "GET"
  proxy                = Nothing
  rawBody              = False
  redirectCount        = 10
  responseTimeout      = ResponseTimeoutDefault
  requestVersion       = HTTP/1.1
}
 (InternalException (HostCannotConnect "raw.githubusercontent.com" [Network.Socket.connect: <socket: 13>: does not exist (Connection refused)]))

Any hints for solving this problem?

I would recommend you try again. Seem like you just got. Transient network issue

[hongyi-zhao]

Really. I confirmed your assertion based on subsequent testings. But I still can't figure out why the stack install command doesn't respect the proxy setting by environment variable as shown below:

# https://docs.haskellstack.org/en/stable/install_and_upgrade/#using-an-http-proxy
$ env http_proxy=127.0.0.1:8080 stack install

you may need to export both HTTP_PROXY and HTTPS_PROXY.

[nvtkaszpir]

either way this is an issue with stack and not with hadolint.
Please see commercialhaskell/stack#5449

[hongyi-zhao]

Thank you for your reminder. The above issue is indeed fired by myself some time ago. But it really has nothing to do with the problem reported there. In fact, the problem here is due to the staled version of stack, and after upgrading via stack upgrade (This operation may also require a proxy.), everything works as expected. See here for more discussion.

[nvtkaszpir]

So are you saying that

$ cd hadolint/hadolint.git/
$ stack install

should be actually replaced with

$ stack upgrade
$ cd hadolint/hadolint.git/
$ stack install

?

[hongyi-zhao]

Yep. See the final compiled/installed working versions of stack and hadolint for my case:
