pub get fails under WSL after ~4 minutes

[mindplay-dk]

Environment

• pub version: 2.6.1
• OS version: Windows 10.0.18362 N/A Build 18362 running Ubuntu 16.04.6 LTS under WSL.
• Are you using the Chinese community mirror or a corporate firewall? No

Problem

Running pub get times out after about four minutes of inactivity:

$ pub get
Resolving dependencies... (4:00.5s)
Connection closed while receiving data

Here's my pubspec.yaml:

name: server_test
description: A web server built using the shelf package.

environment:
  sdk: '>=2.5.0 <3.0.0'

dependencies:
  args: ^1.5.0
  shelf: ^0.7.5
  shelf_router: ^0.7.1
  image: ^2.1.8
  crypto: ^2.1.3

dev_dependencies:
  pedantic: ^1.8.0
  jaguar_hotreload: ^2.0.2
  test: ^1.9.4

Running pub spec with the Windows binaries works fine - would expect the same with the Linux version under WSL.

It runs for about four minutes, then quits - no .packages or .dart_tools appears in the project folder, as it does during pub get under Windows.

Side note: I've been unable to get hot reloading to work under Windows (see here) and that is my only reason for trying the Linux build - I wanted to see if that issue was platform-related.

May be related to #1894.

Can you still reproduce this?

Sorry, not using Dart at the moment.
