Debian apt-get update failing to reach internet sources “W: Failed to fetch”

The Scenario

I have a Debian Jessie 8.3 server on the company network that requires updates/patches installing for the first time. The server is configured to use online sources rather than the ISO/DVD.

The Problem

Every time I run “apt-get update” I get source connection errors “W: Failed to fetch…”

The Solution

My problem was the proxy – I had not yet defined the proxy settings the server should use.

  • vi /etc/apt/apt.conf – create this file if needed
  • Type the following (altering for your specific proxy settings of course):


  • Save the file (:wq!) and retry the “apt-get update” command which now worked, i.e the response was similar to “Hit jessie/main Sources..” and “Get:4 jessie/updates/main Sources [189 kB]”
