• A brief description
  I am trying to run openai's universe on WSL. But while installing the dependencies I faced an error. You may refer to its github repo, https://github.com/openai/universe

• Expected results
  I don't know the expected results because I am running this for the first time.

• Actual results (with terminal output if applicable)
  There were many packages installed. Among them was pillow. Following was the error in WSL which I got

• Your Windows build number
  Windows 10 pro 1607

• Steps / All commands required to reproduce the error from a brand new installation
  Following is the process given on universe's README. Since my WSL has ubuntu 14.04, I used corresponding commands,

Install Universe
To get started, first install universe:
git clone https://github.com/openai/universe.git
cd universe
pip install -e .

If this errors out, you may be missing some required packages. Here's the list of required packages we know about so far (please let us know if you had to install any others).

On Ubuntu 16.04:
pip install numpy
sudo apt-get install golang libjpeg-turbo8-dev make

On Ubuntu 14.04:
sudo add-apt-repository ppa:ubuntu-lxc/lxd-stable # for newer golang
sudo apt-get update
sudo apt-get install golang libjpeg-turbo8-dev make

• Strace of the failing command

• Required packages and commands to install
  numpy
  golang
  golang libjpeg-turbo8-dev

Also how to give permissions to WSL username to read/write the home directory of WSL?

Hi again @hiteshvaidya -- I'm curious, if you retry this a few times, will it eventually work?

There are some known network bugs in the release that you are running, at least one of which ( #616 ) will sometimes cause network sends to hang, which would could cause an error message like the one that you are seeing.

We're told that Microsoft has the fix in-house and is working on releasing it as part of an Insider build. In the meantime, all you can do is either retry the download, or download the file in Windows and access it from WSL and install it manually.

Regarding "the home directory of WSL" -- what directory are you referring to? Do you mean the /home/<username>/ directory in the Linux filesystem? Your default WSL (Linux) user should automatically have full read/write/execute access to that directory.
