  • Try using a different mirror. It might be something temporary. – muru Feb 10 '15 at 9:37
  • I tried multiple mirrors. None have been successful so far – Olivier Feb 10 '15 at 9:40
  • Ok, to test things out, what does wget -S http://archive.ubuntu.com/ubuntu/dists/precise-proposed/Release.gpg say? – muru Feb 10 '15 at 9:43
  • Same thing: Connecting to archive.ubuntu.com (archive.ubuntu.com)|2001:67c:1360:8c01::19|:80... failed: Connection refused. – Olivier Feb 10 '15 at 9:49

    @kenorb: That looks like the reverse issue, i. e. a proxy is (ill-)configured when it shouldn't be, while this question is about a missing proxy configuration. – David Foerster Apr 16 at 10:35

Create the file: /etc/apt/apt.conf

Entered the following line:

 acquire::http::proxy "http://username:password@proxy:8080";
