Não consigo instalar o NMAP devido a dependências não atendidas!

Question

Eu não consigo instalar o nmap devido às seguintes dependências não atendidas

HP-Pavilion-g6-Notebook-PC:~$ sudo apt-get install nmap

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:
nmap : Depends: libstdc++6 (>= 4.9) but 4.8.4-2ubuntu1~14.04.3 is to be   installed
E: Unable to correct problems, you have held broken packages.

Eu já tentei seguir os comandos mas não tive sorte:

sudo apt-get clean
sudo apt-get autoclean
sudo apt-get -f install

Tentou pesquisar a própria dependência ....

AJUDA !!!

    

Answer 1

Tente instalar a dependência. No log do apt-get install, você verá que há uma dependência ausente:

% bl0ck_qu0te%

Portanto, para corrigir isso, tente procurá-lo para ter certeza de que ele está disponível:

apt-cache search libstdc | grep libstdc++6

ou

apt-cache show libstdc++6

Da minha saída, vejo:

Então ... O primeiro vai fazer por mim.

sudo apt-get install libstdc++6 nmap -y

Note que eu incluí o nmap também para que você obtenha o nmap após o libstdc ++ 6.

Método 2 & amp; 3

É tentar um gerenciador de pacotes "diferente" e isso é aptitude.

Aptidão

Você tentará instalar ou corrigir todas as suas dependências ausentes, basta selecionar se deseja ou não seguir suas diretrizes. Infelizmente eu não usei muito, mas cada vez que eu tive que usá-lo, sempre resolvi problemas com o meu apt.

Para instalá-lo:

 sudo apt-get install aptitude -y

Em seguida, execute-o:

 sudo aptitude install nmap
