Seguindo as instruções, ao tentar instalar o gcc, surge a seguinte mensagem:
giann@giann-VirtualBox:~$ sudo apt-get install gcc

Package gcc is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'gcc' has no installation candidateO que é a indisponibilidade de pacote neste caso? Devo buscá-lo através de outro caminho?
