Ignora a seleção explícita do pacote (e força o download do mais recente)

Question

Eu digito sudo apt-get install lua e recebo o seguinte:

Package lua is a virtual package provided by:
  lua5.3:i386 5.3.1-1
  lua5.2:i386 5.2.4-1
  lua5.1:i386 5.1.5-8
  lua50 5.0.3-7
  lua5.3 5.3.1-1
  lua5.2 5.2.4-1
  lua5.1 5.1.5-8
You should explicitly select one to install.

E: Package 'lua' has no installation candidate

Suponho que os autores do pacote desejem que você escolha manualmente o pacote que deseja instalar.

Não há como forçar o download direto do pacote mais recente (neste caso, 5.3)?

Com um hack rápido:

sudo apt-get install \
    $(sudo apt-get install -s lua | \
        awk '/^ +lua/' | \
        cut -d : -f 1 | \
        sort -Vu -k2 | \
        awk 'END {print }')

ou

package="lua"
sudo apt-get install \
    $(sudo apt-get install -s "$package" | \
        awk '/^ +'"$package"'/' | \
        cut -d : -f 1 | \
        sort -Vu -k2 | \
        awk 'END {print }')

$ sudo apt-get install \
    $(sudo apt-get install -s lua | \
        awk '/^ +lua/' | \
        cut -d : -f 1 | \
        sort -Vu -k2 | \
        awk 'END {print }')
