Obtenha o URL dos pacotes instalados usando o apt

  • 772

Como você deve saber, podemos usar apt-get install --print-uris -y package-namee nos mostrar uma lista de URLs, hashsum, etc.

No entanto, se o usarmos para um pacote que já foi instalado no sistema, ele não funcionará:

Reading package lists... Done
Building dependency tree       
Reading state information... Done
package is already the newest version (x.x-x).
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

Então, como posso obter uma lista de URLs necessários usando aptou outras ferramentas CLI como aptitude?

PS: Não quero usar packages.ubuntu.com .

apt

    Nem todos os pacotes instalados terão um URL associado a eles, é claro. No entanto, você poderia usar apt-get dowload:

    $ apt-get download --print-uris wget
'http://archive.ubuntu.com/ubuntu/pool/main/w/wget/wget_1.15-1ubuntu1.14.04.2_amd64.deb' wget_1.15-1ubuntu1.14.04.2_amd64.deb 270522 SHA256:a3f3b049ea373402236a804a5a0952c6ef9b356ba8cc19fbc1f257db6e8f3052

    Esta é a versão candidata mostrada por apt-cache policy, que pode não ser necessariamente a versão instalada.

  2. Parece ser suficiente adicionar o --reinstallsinalizador (pelo menos no meu sistema 16.04), por exemplo

    $ sudo apt-get install --print-uris wget

Reading state information... Done
wget is already the newest version (1.17.1-1ubuntu1.2).
wget set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 73 not upgraded.

    mas

    $ sudo apt-get install --reinstall --print-uris wget
Reading package lists... Done
Building dependency tree
Reading state information... Done
0 upgraded, 0 newly installed, 1 reinstalled, 0 to remove and 73 not upgraded.

After this operation, 0 B of additional disk space will be used.

    NOTA: isso não funciona se o pacote estiver armazenado em cache:

    $ sudo apt-get install --reinstall --download-only wget
