fix: resolve meteor WebSocket race condition and setup apt-get failure

Browse Source 
Meteor: onopen callback used closure variable _ws instead of `this`,
so a double-click during CONNECTING state sent on the wrong socket.
Also clean up any in-progress connection on re-start, not just running ones.

Setup: make apt-get update non-fatal so third-party repo errors
(e.g. stale PPAs on Debian) don't abort the entire install.
