Dependências não satisfeitas ao instalar o Clang ++ [duplicado]

Question

Eu recebo o seguinte erro ao tentar sudo apt-get install Clang ++:

Note, selecting 'clang-tidy-4.0' for regex 'Clang+'
Note, selecting 'python-clang-5.0' instead of 'python-clang-x.y'
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable

Não sei ao certo como resolver essas dependências e não conheço uma boa solução para isso. Eu sou relativamente novo no Linux.

Estou usando o Ubuntu 16.04 LTS

Qualquer informação seria apreciada. Tanto quanto eu tenho sido capaz de ler aqui nos fóruns eu devo remover o programa culpado ou atualizá-lo para a versão que é necessária. Mas a partir da mensagem de erro, não consigo realmente reunir o que é o culpado neste caso.

O problema é que não há pacote Clang++ ou mesmo clang++ , então apt está tratando o nome dado como uma expressão regular e tentando instalar todos os pacotes de correspondência - muitos dos que conflitam entre si:

$ sudo apt-get install --dry-run Clang++

Note, selecting 'python-clang-3.9' for regex 'clang+'

Na verdade, ao contrário de gcc/g++ , clang fornece compiladores C e C ++ como um único pacote - você pode instalar uma versão específica como clang-3.5 ou simplesmente instalar a versão de maior prioridade para o seu sistema através da clang dependency package:

sudo apt install clang
