dotnet-install.sh Fails When global.json Contains rollForward=latestMajor

[RehanSaeed]

When I add the rollForward property to my global.json file like so:

{
  "sdk": {
    "version": "3.1.100",
    "rollForward": "latestMajor"
  }
}

My MacOS build fails with the following error:

You can find my AppVeyor build here and GitHub PR here. My full PowerShell Core script:

if ($isLinux) {
  sudo apt update
  sudo apt install -y zlib1g apt-transport-https
} else {
  brew update
  brew install mono
  brew install mono-libgdiplus
  $env:TERM = 'xterm'
}

Invoke-WebRequest "https://dot.net/v1/dotnet-install.sh" -OutFile "./dotnet-install.sh";
chmod u+x dotnet-install.sh
./dotnet-install.sh --jsonfile global.json

Just tested this again and it's still an issue.

@nguerrera Has anyone taken a look? Are there any updates?

Sorry, I don't work on this project anymore and haven't for months. I was not even aware there was a --jsonfile argument to dotnet-install.sh, maybe it was added after I left, or maybe I just never saw or used it. Either way, I'm not of much help. :) But from the transcript above, it looks like it doesn't do a very good job of parsing the json.

Moving over to the install scripts repo as we've moved the dotnet-install work here. @donJoseLuis for visibility.

Hi @RehanSaeed ,
Thank you for the issue.
We are tracking this in issue #7 and we will get to it as part of our roadmap.
