Unable to locate package while building Docker image

Question

During my Docker container build process, I attemptted to install a few packages using apt-get install. However the process failed to complete because the 3 of the 4 packages could not be found.

Step 1 : RUN apt-get update  && apt-get install -y netcat  ca-certificates  build-essential  libssl-dev

Removing intermediate container 38d22d97ec4a
2015/08/10 12:03:07 The command [/bin/sh -c apt-get update  && apt-get install -y netcat  ca-certificates  build-essential  libssl-dev] returned a non-zero code: 100

At first, I thought this was an issue with my base image, however I have no issues building the container on another VM. Thoughts?

Answer 1

I found this answer in a newer question based on the same problem and it fixed the issue for me.

$ docker-machine restart default      # Restart the environment
$ eval $(docker-machine env default)  # Refresh your environment settings
