Vagrant's Ubuntu 16.04 vagrantfile default password

Question

I'm attempting to deploy and run an Ubuntu 16.04 VM via Vagrant 1.9.1. The Vagrantfile I'm using is from Atlas:

Ubuntu Xenial 16.04 Vagrantfile

I'm using Debian Stretch as the host OS. Vagrant was installed via a .deb available from Vagrant's website.

The Vagrantfile does run and deploy correctly. I can ssh into the VM via both my host OS and using 'vagrant ssh'. However, I have one minor blocker when attempting to ssh in from outside.

The default user in this VM is named 'ubuntu', and looks to have a password set. However, I have no idea what the password is at all, and no docs seem to have the information that I'm looking for. Attempting to set a password via 'passwd' within the VM asks for a current password. Anyone see where this is going?

So my big question is this: has anyone else deployed this same Vagrantfile, and if so, does anyone know what the default user's password is?

Solution 1

^{As of writing this answer: no one ever publicly shared the password for user ubuntu on ubuntu/xenial64 Vagrant box (see #1569237).}

It's not necessary. You can:

• login using SSH key authentication
• change the password using sudo passwd ubuntu (by default ubuntu user has sudo-permissions with NOPASSWD set)

Actually, not only you can, but you should change the password.

Solution 2

The password is located in the ~/.vagrant.d/ubuntu-VAGRANTSLASH-xenial64/20161221.0.0/virtualbox/Vagrantfile as mention by user @prometee in this launchpad discussion #1569237.

Here is mine (line 8):

# Front load the includes
include_vagrantfile = File.expand_path("../include/_Vagrantfile", __FILE__)
load include_vagrantfile if File.exist?(include_vagrantfile)

Vagrant.configure("2") do |config|
  config.vm.base_mac = "022999D56C03"
  config.ssh.username = "ubuntu"
  config.ssh.password = "fbcd1ed4fe8c83b157dc6e0f"

  config.vm.provider "virtualbox" do |vb|
     vb.customize [ "modifyvm", :id, "--uart1", "0x3F8", "4" ]
     vb.customize [ "modifyvm", :id, "--uartmode1", "file", File.join(Dir.pwd, "ubuntu-xenial-16.04-cloudimg-console.log") ]
  end
end

FYI, user @racb mention in the same discusison that the this bug report having been filed to ubuntu and so far no [...] decision has been made yet about it.

Solution 3

The default user and password is:

user: vagrant password: vagrant

Solution 4

The new ubuntu/xenial64 image doesn't come with a default username and password. However you can ssh using an ssh-key generated in your vagrant folder.

Let's say your Vagrantfile is at /vagrant/vm01/Vagrantfile, the ssh-key would be in /vagrant/vm01/.vagrant/machines/..../private_key

You can login to your vagrant vm using this private_key. If the guest machine ask for the key's passphrase, just hit ENTER (specifying a blank passphrase). For example, on my Mac:

ssh -i /vagrant/vm01/.vagrant/..../private_key <your vm user>@<your vm ip>:<your vm port>

If you still want to log in using username and password, after logging in using the private_key, you can add your own user for logging in later:

# create a user for log in
sudo useradd yourusername

# specify a password
sudo passwd yourusername
# then type your password when prompted

# add the user to sudo group
sudo adduser yourusername sudo    

# create a home folder for your user
sudo mkdir /home/yourusername

# add a shell command for your user (normally /bin/bash)
sudo vim /etc/passwd
# find yourusername line, and add /bin/bash to the end.
# the end result would look like this:
yourusername:x:1020:1021::/home/yourusername:/bin/bash

Now you can ssh using the new username and password.

It's worth mentioning that this breaks the vagrant standard of having the user/pass both default to 'vagrant'. vagrantup.com/docs/boxes/base.html

Thanks for linking to the Launchpad bug report! Following through the comments, I found a link to another Ubuntu 16.04 Vagrantfile which I downloaded and tested: atlas.hashicorp.com/bento/boxes/ubuntu-16.04 This one used the old username and password of "vagrant/vagrant", which allowed me to do my tests headache-free. :)

The path of the mentioned Vagrantfile has changed some (probably as a result of a more recent vagrant version). It now has /boxes in the path, like so: ~/.vagrant.d/boxes/ubuntu-VAGRANTSLASH-xenial64/20171028.0.0‌​/virtualbox/Vagrantf‌​ile.

How to add my public SSH key to the virsual machine if I can't login to it because I don't know login and password?

[mastazi]

@Finesse not sure if you still need an answer to this, but you can usually login without password by typing the command vagrant ssh

[wal]

you could also delete the user sudo deluser --remove-home ubuntu and then created your own
