Se eu tentar executar sudo apt-get install python-box2d, recebo esta mensagem de erro sem sentido:
Reading package lists... Done

You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
libcv-dev : Depends: libopencv-core-dev but it is not going to be installed
libcvaux-dev : Depends: libopencv-core-dev but it is not going to be installed

libopencv-contrib-dev : Depends: libopencv-contrib2.3 (= 2.3.1-7) but it is not going to be installed
libopencv-features2d-dev : Depends: libopencv-features2d2.3 (= 2.3.1-7) but it is not going to be installed
libopencv-flann-dev : Depends: libopencv-core-dev (= 2.3.1-7) but it is not going to be installed

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
Se eu tentar executar o sugerido sudo apt-get -f install, ele tentará instalar todos os itens acima, mas todos falharão com erros como:
dpkg: error processing /var/cache/apt/archives/libopencv-video2.3_2.3.1-7_amd64.deb (--unpack):
trying to overwrite '/usr/lib/libopencv_video.so.2.3.1', which is also in package libopencv2.3 2.3.1+svn6514+branch23-12~oneiric
No apport report written because MaxReports is reached already
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
O que está acontecendo aqui? Pelo que eu sei, o Box2D não usa nenhum desses pacotes OpenCV (é uma biblioteca de física 2D, enquanto o OpenCV é uma biblioteca de processamento de visão) e, mesmo que usasse, por que todos os pacotes estão quebrados?
Responder1
Acabou sendo a culpa do repositório de baixa qualidade usado porMirante. Aparentemente, ele fornece pacotes que entram em conflito com os do repositório padrão. Removi seu PPA e desinstalei todos os pacotes quebrados e isso resolveu o erro.
Responder2
exclua manualmente todas as bibliotecas OpenCV e tente executar o comando abaixo.
sudo dpkg -r libopencv*
