Jing Qiu 750d72873d Always combine RUN apt-get update with apt-get install in the same RUN

statement.

From the [docs](https://docs.docker.com/engine/userguide/eng-image/dockerfile_best-practices/#build-cache) in March 2017:

Always combine RUN apt-get update with apt-get install in the same  RUN statement, for example

RUN apt-get update && apt-get install -y package-bar

Using apt-get update alone in a RUN statement causes caching issues and subsequent apt-get install instructions fail.
