Depurar apt / Instalando Docker - Não é possível localizar o pacote docker-ce

Question

Eu segui as instruções oficiais para o Docker instalação - Debian Jessie.

• Em /etc/apt/sources.list diz agora,

  deb [arch=amd64] https://download.docker.com/linux/debian jessie stable

• apt-get update parece baixar os pacotes corretamente (saída abaixo)

• mas, em apt-get install docker-ce , o sistema informa que "não foi possível localizar o pacote docker-ce".

Como posso depurar o que está acontecendo? Nunca tive isso antes.

Saída de apt-get update :

Answer 1

Para instalar o docker-ce no debian jessie:

Depois de adicionar deb [arch=amd64] https://download.docker.com/linux/debian jessie stable ao seu /etc/sources.list . (você não precisa do pacote software-properties-common ou do comando add-apt-repository )

Instale o pacote necessário:

sudo apt-get update
sudo apt-get install apt-transport-https ca-certificates curl

Adicione a chave gpg :

curl -fsSl https://download.docker.com/linux/debian/gpg | sudo apt-get key add -

Atualize e pesquise docker-ce package:

sudo apt-get update
apt-cache search docker-ce

Em seguida, instale o pacote docker-ce :

sudo apt-get install docker-ce
