Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

The reporter tried to install sudo-ldap which conflicts with sudo which doesn't want to be removed.

Removing sudo (1.8.16-0ubuntu1.2) ...
You have asked that the sudo package be removed,
but no root password has been set.
Without sudo, you may not be able to gain administrative privileges.

If you would prefer to access the root account with su(1)
or by logging in directly,
you must set a root password with "sudo passwd".

If you have arranged other means to access the root account,
and you are sure this is what you want,
you may bypass this check by setting an environment variable
(export SUDO_FORCE_REMOVE=yes).

Refusing to remove sudo.

E: Sub-process /usr/bin/dpkg returned an error code (1)
