Why can't I `sudo apt-get update && sudo apt-get install google-cloud-sdk`?

Question

I followed the instructions in this url, https://cloud.google.com/sdk/docs/quickstart-debian-ubuntu and when I typed the command

sudo apt-get update && sudo apt-get install google-cloud-sdk

I got this errors:

E:Malformed line 5 in source list/etc/apt/sources.list.d/google-cloud-sdk.list(dist parse).
E: The list of sources could not be read.

I wrote the above command in virtualenv. I cannot understand why this error happens. All other step is completed, so I cannot understand why this happens. How should I fix this?

Answer 1

this helped me:

curl https://sdk.cloud.google.com | bash

after:

exec -l $SHELL

and finally:

gcloud init

it's an interactive installer from google, more info here
