vagrant + Permission denied Mint

Question

I fight with it only 2 days. I see many similar post but i can't solve my problem.

I have Mint 18 as main OS (4.4.0-21-generic #37-Ubuntu SMP Mon Apr 18 18:33:37 UTC 2016 x86_64 x86_64 x86_64 GNU/Linu) and now I have:

virtualbox 5.0.40 r115130
Vagrant 1.8.4 + vagrant-vbguest (0.14.2)

Vm installed correctly. When I try run "vagrant ssh" I see:

Permission denied (publickey)

My config:

Vagrant.configure(2) do |config|
  config.vm.box = "debian/jessie64"
  config.vm.network "forwarded_port", guest: 80, host: 8080, auto_correct: true
  config.vm.network "private_network", ip: "192.168.56.106"
  config.vm.synced_folder '.', '/home/vagrant'  
end

Synced_folder works correct.

vagrant ssh-config

 Host default
  HostName 127.0.0.1
  User vagrant
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no
  IdentityFile /home/wiktor/NetBeansProjects/PhpProject1/.vagrant/machines/default/virtualbox/private_key
  IdentitiesOnly yes
  LogLevel FATAL

And: ssh -i /home/wiktor/NetBeansProjects/PhpProject1/.vagrant/machines/default/virtualbox/private_key -v vagrant@localhost -p 2222

I don't understand this error. Maybe vagrant can't generate public key.

After connect to VM through VirtualBox and runed "ls -la /home/vagrant" I didn't see directory ".ssh". Is that correct?

I tried to run virtualbox 5.1 and vagrant 1.8.5 but I have the same errors.

When I used Windows10 after incorrect public/private key, this requested a password to the vagrant user. On Mint returns the error. I changed chmod and edited /etc/ssh/sshd_config on guest and main OS. It's didn't help.

Can anyone help?

The problem is due to the below line in your vagrantfile

  config.vm.synced_folder '.', '/home/vagrant'

The authorized_keys file for the vagrant user is located in /home/vagrant/.ssh inside the vagrant machine, which enables to ssh into the vagrant box.

As you are mounting your current directory to /home/vagrant, all the contents of /home/vagrant are over-written and there is no authorized_keys file.

Change the mount path to anything except /home/vagrant, and you will able to ssh into the machine. As example

  config.vm.synced_folder '.', '/home/vagrant/somepath'

vagrant + Permission denied Mint
