Estou usando o 14.04. Inicialmente eu tinha um libboost-all-dev instalado que era a versão 1.54. Um pacote separado que eu estava tentando instalar a partir do código fonte, precisava do libboost1.55, e a única maneira de instalá-lo era desinstalar o 1.54 e vários outros pacotes que dependiam do 1.54. Agora, eu pensei que eu poderia reinstalá-los depois de instalar o libboost1.55-all-dev, mas isso não parece ser o caso, como quando eu tento reinstalá-los, ele me diz que isso depende de 1.54. Um exemplo é onde eu recebo:

É possível reinstalar esses pacotes e fazê-los funcionar com o libboost1.55-all-dev? Se não, alguém poderia me ajudar com minhas opções, considerando que eu preciso desses pacotes (por exemplo, cgal) e eu preciso do pacote original que eu estava tentando instalar da fonte?
