Upfrading from Ubuntu 14.03 to Ubuntu 16.0

[Ralf Mardorf]

Was the issue caused by the package
http://packages.ubuntu.com/xenial/ttf-mscorefonts-installer ?

So you're using an encrypted home/ partition?
It asks for a username and password to allow access to the partition?

If so, this might be irrelevant:

You might need to continue doing this:

"Update Failure

If there was an update that made your system non-bootable and they have
fixed it in the repositories, you can use the Live CD to run apt-get to
get the new files to fix your system.

    Boot the Ubuntu Live CD.

    Press Ctrl-Alt-F1

    sudo mount /dev/sda1 /mnt

    sudo mount --bind /dev /mnt/dev

    sudo mount --bind /proc /mnt/proc

    sudo mount --bind /sys /mnt/sys

    sudo chroot /mnt

    apt update

    apt upgrade 

If you have trouble accessing your network after chroot, you probably
use DHCP and can work around this by adding OpenDNS name servers to
your /etc/resolv.conf after you use chroot:

nameserver 208.67.222.222
nameserver 208.67.220.220" -
https://help.ubuntu.com/community/LiveCdRecovery#Update_Failure

/dev/sda1 not necessarily is your root directory's partition, see
https://help.ubuntu.com/community/LiveCdRecovery#Finding_your_root_partition .

However, _do not_ chroot and apt upgrade yet. Also _do not_ change the
password yet.

_But_ instead mount and run

  cat /mnt/etc/lsb-release
  grep -i xenial /mnt/etc/apt/sources.list
  cat /mnt/moonstudio/etc/default/keyboard

and post the output.
