dpkg는 이를 볼 수 있지만 apt-get은 이를 제거할 수 없습니까?

(질문과 유사Debian에서 기본 VBoxGuestAdditions 제거하지만 Ubuntu가 설치되어 있는데 거기의 솔루션이 나에게 적합하지 않습니까? )

실제로 문제는 virtualbox나 Linux 게스트 추가가 아니라 dpkg/apt-get에 있는 것 같습니다.

host:/media/VBOXADDITIONS_4.2.10_84104$ dpkg -l | grep virtualbox
rc  virtualbox-guest-utils                 4.1.12-dfsg-2ubuntu0.2                  x86 virtualization solution - non-X11 guest utilities
rc  virtualbox-guest-x11                   4.1.12-dfsg-2ubuntu0.2                  x86 virtualization solution - X11 guest utilities
host:/media/VBOXADDITIONS_4.2.10_84104$ sudo apt-get remove virtualbox-guest-utils virtualbox-guest-x11

VirtualBox Guest Additions installer
You appear to have a version of the VBoxGuestAdditions software
on your system which was installed from a different source or using a
different type of installer.  If you installed it from a package from your
Linux distribution or if it is a default part of the system then we strongly
recommend that you cancel this installation and remove it properly before
installing this version.  If this is simply an older or a damaged
installation you may safely proceed.

Do you wish to continue anyway? [yes or no]
no

Cancelling installation.

그러면 dpkg는 virtualbox-guest-utils 및 virtualbox-guest-x11을 볼 수 있지만 apt-get은 이를 제거할 수 없습니까? !
