Tudo estava funcionando normalmente, mas agora o libstdc ++ parece estar quebrado. Então eu tento reinstalá-lo. Coisas como:
sudo apt-get remove stdc++
sudo apt-get autoclean
sudo apt-get -f install
sudo apt-get -u dist-upgrade
não ajuda. E o que eu tenho:
$ sudo apt-get install stdc++

libstdc ++ não é um nome de pacote binário. Como um pacote que corresponde ao nome libstdc ++ não é encontrado, o apt-get pesquisa pacotes que correspondem a este regex e, portanto, deseja instalar o 4.4, 4.6, 4.7 e 4.8 e os arquivos -doc e -dbg associados Em vez disso, os pacotes que você provavelmente está procurando por libstdc ++ 6
