Vagrant ssh encountered an unknown error

Question

I was trying to run vagrant up for an existing vagrant setup. I get this following error:

I am running a hashicorp/precise 32 box, and the IP address in my config file is 192.168.33.10.

EDIT:

After editing my vagrantfile -> ansible.verbose = 'vvvv' This was the output of sudo vagrant up:

Any idea what the problem is? I'm not quite sure why this would happen, as it worked fine just a few months ago -- I haven't touched this project in a while.

Answer 1

First of all, sorry but I couldn't post as a comment to your answer.

Anyway if this is a permission related issue then it might be because at some point you ran vagrant with sudo.

Vagrant then creates files as a root user and any future attempts will run into permission problems.

Just chowning the .vagrant in your project folder to the current user should work, although you might also have to chown the .vagrant.d folder in your home directory.

Hope this helps someone!

Answer 2

Well, I feel somewhat silly because I ended up resolving my own errors by working on something that wasn't exactly related to the project..

Essentially the other day I ran into some SSH key configuration issues -- it seems like one of my keys was doing something really weird. I created new keys, got rid of the old ones, updated config for my web servers, etc.

Today when re-visting the thread, I realized that 'vagrant up' runs just fine...

In the past, I always had to run 'sudo' because I would get some sort of strange errors indicating I didn't have permission.

Now I am able to run it without sudo, and it works like a charm.

Thanks to all those that contributed!

Answer 3

This is a bit of a shot in the dark, since we don't have much details about your Vagrantfile or your ssh configuration, but you probably should not run vagrant up as sudo.

If running vagrant up instead of sudo vagrant up doesn't solve your problem, please post the result of the vagrant ssh-config command and the Ansible provisioning section from your Vagrantfile.
