Error while running fab vagrant setup_vagrant

[Werner0]

I get the following error when I try to run Fabric configuration. I'm accessing the internet through a company proxy.

[127.0.0.1:2222] out: gpg: requesting key E084DAB9 from hkp server keyserver.ubuntu.com
[127.0.0.1:2222] out: gpg: keyserver timed out
[127.0.0.1:2222] out: gpg: keyserver receive failed: keyserver error
[127.0.0.1:2222] out:

Fatal error: sudo() received nonzero return code 2 while executing!

Requested: sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys E084DAB9
Executed: sudo -S -p 'sudo password:'  /bin/bash -l -c "sudo apt-key adv --keyserver     
hkp://keyserver.ubuntu.com:80 --recv-keys E084DAB9"

Aborting.
Disconnecting from 127.0.0.1:2222... done.

SOLVED

First install a proxy configuration plugin for vagrant with:

vagrant plugin install vagrant-proxyconf

Then add the following to the Vagrantfile:

config.proxy.http     = "http://proxy.company.address:port"
config.proxy.https    = "http://proxy.company.address:port"
config.proxy.no_proxy = "localhost,127.0.0.1"
