I had this problem recently where apt install wget does not find anything  As it turns out apt update was never run  apt update apt install wget  After discussing this with a coworker we mused that apt update is likely not run in order to save both time and space in the docker image

You need to install it first  Create a new Dockerfile  and install wget in it   FROM ubuntu 14 04 RUN  apt-get update      amp  amp  apt-get install -y wget      amp  amp  rm -rf  var lib apt lists     Then  build that image   docker build -t my-ubuntu     Finally  run it   docker run my-ubuntu wget https   downloads-packages s3 amazonaws com ubuntu-14 04 gitlab 7 8 2-omnibus 1-1 amd64 deb

If you re running ubuntu container directly without a local Dockerfile you can ssh into the container and enable root control by entering su then apt-get install -y wget
