Comment 12 for bug 1408495

Permissions on /etc/default/keyboard were:
c------------

while on the default were
-rw-r--r--r

So workaround copying resulted in
-rw-r--r--
so install completed.

BTW, this is US so this is what keyboard looked like:

ubuntu@ubuntu:~$ cat /etc/default/keyboard
# Check /usr/share/doc/keyboard-configuration/README.Debian for
# documentation on what to do after having modified this file.

# The following variables describe your keyboard and can have the same
# values as the XkbModel, XkbLayout, XkbVariant and XkbOptions options
# in /etc/X11/xorg.conf.

XKBMODEL="pc105"
XKBLAYOUT="us"
XKBVARIANT=""
XKBOPTIONS=""

# If you don't want to use the XKB layout on the console, you can
# specify an alternative keymap. Make sure it will be accessible
# before /usr is mounted.
# KMAP=/etc/console-setup/defkeymap.kmap.gz

which went on to code 2 and fail.

Your workaround worked.

Maybe the bug is the permissions
-c----------instead of
-rw-r--r--

Having said that, I didn't copy the permissions, could even have been
c----------

Maybe all I had to do was change permissions?
