Steps to Reproduce:

1. Installed fresh copy of VScode using .deb package
2. Installed C/C++ extensions 0.11.0; restart vscode
3. When VScode starts up it tries to update dependencies; sometimes if fails during downloadPackages (varies as to which package it fails on:

Updating C/C++ dependencies...

3b: sometimes it manages to download all four package dependencies but fails on the install of one of them, for example:
