Pacotes não estão instalando!

Question

Estou tentando instalar pacotes usando apt-get

Estes são os seguintes pacotes:

root@ubunto:/# sudo apt-get install build-essential libssl-dev libcurl4-gnutls-dev libexpat1-dev gettext unzip
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package libcurl4-gnutls-dev 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: Unable to locate package build-essential
E: Unable to locate package libssl-dev
E: Package 'libcurl4-gnutls-dev' has no installation candidate
E: Unable to locate package libexpat1-dev
E: Unable to locate package gettext
E: Unable to locate package unzip

Meu principal objetivo é instalar o pacote make , que eu preciso instalar manualmente uma versão inferior do PHP

Foi o que aconteceu:

root@ubunto:~/php-5.4.31# make
The program 'make' is currently not installed. You can install it by typing:
apt-get install make

E então eu continuo e faço 'apt-get install make'

root@ubunto:/# apt-get install make
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package make 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 'make' has no installation candidate

Estou executando o Ubuntu 14.04.1 LTS em uma máquina virtual (Hyper-V) se isso ajudar

Eu tive o problema das PME apenas alguns dias antes. Tente correr

# apt-get update

Seu apt-repositório está desatualizado. Esse pode ser o problema.
