Como posso resolver este problema?

    

Answer 1

O problema principal é perdido /etc/apt/sources.list . Você pode recriá-lo com:

cat <<EOF | sudo tee /etc/apt/sources.list
deb http://archive.ubuntu.com/ubuntu artful main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu artful-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu artful-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu artful-backports main universe restricted multiverse
EOF

Em seguida, execute

sudo apt-get update
sudo apt-get dist-upgrade
sudo apt-get install apache2

    

Answer 2

Teste sudo apt-get update e, em seguida, sudo apt-get install apache2 . Eu recomendo instalar o LAMP Stack completo usando tasksel

sudo apt-get install tasksel

sudo tasksel para iniciá-lo Selecione o servidor LAMP e instale-o. Espero que ajude.
