Updated Ubuntu now cannot login

[KyleFreise]

So I performed upgrades to Ubuntu on the original MineMeld OVA VM and can no longer login with the default username and password.  This is NOT the UI password, but rather to log into the OS itself.

What can I do to recover this account?  Is there a hidden default root account?

Hi @Sly_Cooper,

you can update MineMeld instance using a standard Ubuntu mechanism, this will bring your Ubuntu to 14.04.5:

$ sudo apt-get update
$ sudo apt-get dist-upgrade

DO NOT USE "do-release-upgrade -d". It would upgrade your instance to Ubuntu 16.04 and this is not supported yet.

Before the upgrade I do a backup of current config and data:

$ sudo service minemeld stop
$ sudo tar -cvzf minemeld-backup.tar.gz /opt/minemeld/local
$ sudo service minemeld start

In case of errors, to restore in a new instance:

$ sudo service minemeld stop
$ cd /
$ sudo -u minemeld tar -xvzf minemeld-backup.tar.gz
$ sudo service minemeld start

How would you go about doing that, if you can't log in?  I'm having the same issue.  I haven't logged in to the CLI lately, and now it's not letting me in at all.  I'm also unable to log in in single user mode.
