When I run apt-get update (on Ubuntu 12.04) I keep getting these errors:

Err http://security.ubuntu.com precise-security Release.gpg
  Could not resolve 'false'
Err https://get.docker.io docker/main amd64 Packages
  Couldn't resolve proxy 'false'
Err https://get.docker.io docker/main i386 Packages
  Couldn't resolve proxy 'false'

When run nslookup on those addesses it works.

/etc/resolv.conf:

nameserver 8.8.8.8

Any idea what could cause this error?

Do you get the errors for all repositories or just the ones you show? Do all errors complain about proxy? In your post, the first one does not. Please post the contents of /etc/apt/sources.list and the output of grep -Ri proxy /etc/apt/apt.conf.d –  terdon Mar 5 at 2:42
    
Thanks, I didn't know where to look for proxy settings. grep -nHRi proxy /etc/apt/apt.conf.d: /etc/apt/apt.conf.d/proxy:1:Acquire::http::Proxy "http://false:8080"; I'm using puppet and probably after some update it thinks that false is a reasonable value for proxy. –  Tombart Mar 5 at 8:57
