Answer 1

libstdc++ não é um nome de pacote binário. Como um pacote que corresponde ao nome libstdc++ não foi encontrado, apt-get pesquisa pacotes que correspondem a essa regex e, portanto, deseja instalar 4.4, 4.6, 4.7 e 4.8 e os arquivos associados -doc e -dbg . O mesmo se aplica para clang++

Em vez disso, os pacotes que você está procurando provavelmente são libstdc++6 (para o seu primeiro comando) e libc++1 (para o segundo comando).
