Установите 32-разрядную версию libopencv-dev на 64-разрядную версию 12.04 [дубликат]

Я уже установил 64-битную версию пакета libopencv-dev и теперь хочу установить 32-битную версию.

Я попробовал команду:

sudo apt-get install libopencv-dev:i386

, но получил следующее сообщение об ошибке

Есть ли конфликт с 64-битной версией?
