While trying to build my repository inside a docker container, I need to install git:
FROM ubuntu:14.04
RUN apt-get update
RUN apt-get upgrade
RUN apt-get clean
RUN apt-get install -y git
to build the container i run the following command:
sudo docker build .
I get the following error on every package i try to install:
E: Unable to locate package git
The command '/bin/sh -c apt-get install -y git' returned a non-zero code: 100
All the answers i found were claiming that i need to run apt-get update first, which i do.
EDIT:
Tried to run all of the commands in one line:
RUN apt-get update && apt-get install -y git
which yielded the following error:
Err http://archive.ubuntu.com trusty InRelease
Err http://archive.ubuntu.com trusty-updates InRelease
Err http://archive.ubuntu.com trusty-security InRelease
Err http://archive.ubuntu.com trusty Release.gpg
Could not resolve 'archive.ubuntu.com'

From your updated output, you show your apt-get update is failing, DNS resolution failed. This is a network connectivity issue you need to resolve first before you'll be able to build images that pull packages from the network.
