Sometimes things go wrong during vagrant setup especially if have set it up already. You might get errors like “Authentication Failure” during “vagrant up” command. It is troublesome to get into the VM if there is no ssh key.
Type in
vagrant ssh-config
To see whats happening.
make sure u have ssh keys already.
then get into the vm with user “vagrant” and passwd “vagrant”
put id_rsa.pub into ~/.ssh/authorized_keys
you should be able to ssh into vagrant vm with “vagrant ssh” now.
