Os seguintes pacotes possuem dependências não atendidas quando desinstalar gcc [closed]

Question

Estou instalando o opencv 2.4.5, mas ele causa o mesmo erro que nesta página. -gcc-47-e-up-não-suportado / "> link . Para corrigi-lo, temos que instalar o gcc 4.6 em vez de 4.7 ou superior. Mas quando eu removo o gcc 4.6 por "sudo apt-get remove .." ou "autoremove", um erro aparece assim:

Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation:
The following packages have unmet dependencies:
 dkms : Depends: gcc but it is not going to be installed
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

Esta é a versão do meu gcc:

gcc (Ubuntu/Linaro 4.7.3-1ubuntu1) 4.7.3

2) Diga ao cmake para usar um compilador específico: CC=gcc-4.6 CXX=g++-4.6 cmake ../
