I have been using some packages by installing them using the sudo apt-get command in the cloud shell. But now I want to make it permanent. I got this message in the shell
You are running apt-get inside of Cloud Shell. Note that your Cloud Shell
machine is ephemeral and no system-wide change will persist beyond session end.
You can customize your environment to permanently include this package by
updating your environment at https://cloud.google.com/console/cloudshell/environment/view.
So how to customize the cloud environment to include a package permanently?
