Steps to reproduce the problem:
1. docker run -it ubuntu:14.04 /bin/bash
2. apt-get update && apt-get install git
3. git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
4. export PATH=$PATH:/path/to/depot_tools
5. mkdir chromium && cd chromium
6. fetch --no-history chromium

What is the expected behavior?
$ fetch --no-history chromium
Running: gclient root
Running: gclient config --spec 'solutions = [
  {
    "managed": False,
    "name": "src",
    "url": "https://chromium.googlesource.com/chromium/src.git",
    "custom_deps": {},
    "deps_file": ".DEPS.git",
    "safesync_url": "",
  },
]
'
Running: gclient sync --no-history
Running: git submodule foreach 'git config -f $toplevel/.git/config submodule.$name.ignore all'
Running: git config --add remote.origin.fetch '+refs/tags/*:refs/tags/*'
Running: git config diff.ignoreSubmodules all

What went wrong?
$ fetch --no-history chromium
Running: gclient root
Running: gclient config --spec 'solutions = [
  {
    "managed": False,
    "name": "src",
    "url": "https://chromium.googlesource.com/chromium/src.git",
    "custom_deps": {},
    "deps_file": ".DEPS.git",
    "safesync_url": "",
  },
]
'

Did this work before? N/A 

Chrome version:   Channel: canary
OS Version: Ubuntu 14.04.5 LTS

In short, it seems as if there is no DEPS for wget in "install-build-deps.sh" and also I guess it's strongly related to the  Issue 650482 . https://bugs.chromium.org/p/chromium/issues/detail?id=650482

Since there is no wget installed in a fresh docker container, the error occurs in executing "gclient sync" command. Finally the error has gone after installing wget. (It may be applied to other linux systems without wget)
