Vagrant "ssh_exchange_identification: connection closed by remote host" after updating Ubuntu guest

This is the second time this happens to me: I created an Ubuntu virtual machine using Vagrant and after starting:

Sudo apt-get upgrade sudo apt-get upgrade

I got it:

Timed out while waiting for the machine to boot. This means that
Vagrant was unable to communicate with the guest machine within
the configured ("config.vm.boot_timeout" value) time period.

If you look above, you should be able to see the error(s) that
Vagrant had when attempting to connect to the machine. These errors
are usually good hints as to what may be wrong.

If you're using a custom box, make sure that networking is properly
working and you're able to connect to the machine. It is a common
problem that networking isn't setup properly in these boxes.
Verify that authentication configurations are also setup properly,
as well.

If the box appears to be booting properly, you may want to increase
the timeout ("config.vm.boot_timeout") value.

When I debug an ssh connection, I see the following:

vagrant ssh -- -vvv
OpenSSH_6.9p1, LibreSSL 2.1.8
debug1: Reading configuration data ~/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 20: Applying options for *

debug2: ssh_connect: needpriv 0

debug1: Connection established.
debug1: key_load_public: No such file or directory
debug1: identity file ~/.vagrant/machines/default/virtualbox/private_key type -1
debug1: key_load_public: No such file or directory
debug1: identity file ~/.vagrant/machines/default/virtualbox/private_key-cert type -1
ssh_exchange_identification: Connection closed by remote host

It happened to me on Linux and the same thing happened on Mac OS.

Maybe there is a mistake, or I'm doing something wrong.

I ran into this problem with the laravel / homestead 1.0.1 field on OSX 10.11.6 and Vagrant 1.9.1.

This is what worked for me after I got the same error.

From your terminal, navigate to the folder with your .vagrant directory and run the following commands:

 $ vagrant destroy

 $ vagrant up

 $ vagrant ssh

And you have to go back and work. Happy coding!
