Estou tentando instalar o google cloud sdk usando o curl do cygwin.

    

Answer 1

Eu tentaria baixar o script primeiro e depois executá-lo em bash .

Exemplo

$ curl -v https://dl.google.com/dl/cloudsdk/release/install_google_cloud_sdk.bash -O 
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
  0     0    0     0    0     0      0      0 --:--:-- --:--:-- --:--:--     0* About to connect() to dl.google.com port 443 (#0)

Assim que terminar de fazer o download, você deverá ter um arquivo como este:

$ ls -l
total 4
-rw-rw-r--. 1 saml saml 3622 Feb 27 02:07 install_google_cloud_sdk.bash

A partir daqui, você pode executá-lo manualmente:

$ bash install_google_cloud_sdk.bash 
curl -f "https://dl.google.com/dl/cloudsdk/release/google-cloud-sdk.tar.gz" > "/tmp/tmp.dlj5Kju8Tp/google-cloud-sdk.tar.gz"
  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100  364k  100  364k    0     0   521k      0 --:--:-- --:--:-- --:--:--  521k

Answer 2

Você pode usar o curl em tudo? Por exemplo. curl google.com .

Isso aconteceria se você estivesse em um ambiente como a Universidade de York, onde é necessário usar o servidor proxy da universidade e as conexões diretas são bloqueadas.

Tecnicamente, o erro "a rede está inacessível" acontece depois, quando o curl tenta desesperadamente voltar ao IPv6. O erro original é "Falha na conexão".
