Eu quero instalar o g ++ no meu laptop (ubutu 14.04 LTS), mas ele mostra os seguintes erros -
maddman@MADDY-PC:~/Desktop$ sudo apt-get install g++
Reading package lists... Done

Reading state information... Done
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:
g++ : Depends: g++-4.8 (>= 4.8.2-5~) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Unable to correct problems, you have held broken packages.
Também toda vez que eu executo a atualização, ele mostra o seguinte erro
W: Failed to fetch http://ppa.launchpad.net/picaso/octave/ubuntu/dists/trusty/main/binary-amd64/Packages 404 Not Found
W: falha ao buscar link 404 não encontrado
E: Some index files failed to download. They have been ignored, or old ones used instead.
Depois de alguma pesquisa, encontrei uma resposta relevante aqui ... Como resolvo dependências não satisfeitas depois de adicionar um PPA?
However, for me the following command worked out
sudo apt-get instale ppa-purge
e então eu corri o comando para instalar o g + + e ele instalado com sucesso.
