Error with go get private-repo

$ go get -v some.private.repo.git
go: finding some.private.repo.git latest

If you get similar error 410 Gone then it might be because of the URL being a private repo

Solution

The new GOPRIVATE environment variable indicates module paths that are not publicly available. It serves as the default value for the lower-level GONOPROXY and GONOSUMDB variables, which provide finer-grained control over which modules are fetched via proxy and verified using the checksum database.

• in cmd.exe:

  set GOPRIVATE=some.private.repo.git
  set GONOSUMDB=some.private.repo.git
  

• in Powershell:

  $env:GOPRIVATE = "some.private.repo.git"
  $env:GONOSUMDB = "some.private.repo.git"
  

Note

• GOPRIVATE = "some.private.repo.git/" will not work because of / at the end
• GOPRIVATE = "some.private.repo.git,some.otherprivate.repo.git" you can add more than one private repo by separating them with comma (,)

• Connection Time Out Error on EC2

  exit status 128:
  fatal: unable to connect to git-codecommit.us-west-2.amazonaws.com:
  git-codecommit.us-west-2.amazonaws.com[0: ww.xx.yy.zz]: errno=Connection timed out
  

  In this case, you will have to provide ec2 an access to Codecommit and then set this environment variable

  set GONOSUMDB=git-codecommit.us-west-2.amazonaws.com/v1/repos/some.private.repo.git
  

  Better way will be to simply store this variables in /etc/environment permanently. /etc/environment stores all key-value pairs of environment variables
