VM apt-get install - network is unreachable

Question

I have a Vagrant backed Ubuntu VM which I'm trying to do some performance testing on. In order to do so I'm trying to install gdb

When I run apt-get install I see the following:

vagrant@ubuntu-1204:~$ sudo apt-get install gdb
sudo: /etc/sudoers.d/vagrant is mode 0644, should be 0440

Far as I can tell, there's some network configuration missing but I'm at a bit of a loss where. I can ping google.com and get a successful response so I'm a bit puzzled why security.ubuntu.com appears to be going out on 192.168.0.0

This is what I see for ifconfig

Any help would be much appreciated!

UPDATE

Tried adding

config.vm.network "public_network", bridge: [
    "en0: Wi-Fi",
    "en3: Thunderbolt"
]

But the issue persists.

Here is routing table:

I've also tried ping-ing the Ubuntu servers which looks fine:

Solution 1

Vagrant uses VirtualBox. So go to your instance and check if your network card is correctly bridged. You can configure that in your Vagrantfile. For example my line for my Macbook to bridge the network to my WLAN card.

server.vm.network "public_network", bridge:'en0: WLAN (AirPort)'

perhaps that help for your problem.

http://docs.vagrantup.com/v2/networking/public_network.html

Check your VBox settings. If there is a correct network bridge.

Have you set another gateway? Perhaps make a new instance and check if that is working. Perhaps you have a misconfiguration anything in your package manager.

Solution 2

The strange thigs is that apt-get is connecting 192.168.0.0:59875.

Are you using any proxy for apt-get?

Check this with:

$ apt-config dump Acquire::http::Proxy
$ echo $http_proxy

Still no luck, added to my question.

[timothyclifford]

Yes it looks like I am, possibly setup by person who created the VM I suppose? Should I try without it?

[timothyclifford]

Think I found it, in /etc/apt/apt.conf.d/01proxy I can see Acquire::https::Proxy "http://192.168.0.0:59875/

[timothyclifford]

I tried removing this line but the proxy is still being used. Do I need to refresh apt configuration somehow? (sorry I'm still a bit new to *nix world)

[timothyclifford]

Found it (not sure if best fix) but export http_proxy= seems to clear it out. Is there a better way?
