If you prefer automatic updates, you can install the Google Cloud CLI using a snap package on Ubuntu systems. This package contains the gcloud CLI, gcloud alpha, gcloud beta, gsutil, docker-credential-gcloud, and bq commands only. It doesn't include kubectl or the App Engine extensions required to deploy an application using the gcloud CLI. If you need these components, install the Debian package instead. 
-  If you have the old snap package, google-cloud-sdk, installed, remove it at the command line:snap remove google-cloud-sdk 
-  At the command line, install the gcloud CLI snap package: snap install google-cloud-cli --classic 
-  Optional. To add the gcloud CLI tools to your PATHand enable command completion in your Bash shell, source/path/to/gcloud/completion.bash.incin your profile.For Zsh shells, use /path/to/gcloud/completion.zsh.incinstead.
-  To initialize the gcloud CLI and get started, run gcloud init:gcloud init
