I have utilized the following steps to install terraform in Ubuntu 16.04
Download Terraform for Linux 64 bit version.
Save the downloaded version in a specific folder. (Example: /home/user/terra)
Within the folder where the downloaded version is saved, use “unzip” command:
unzip terraform
Set the path:
export PATH=$PATH:/home/user/terraform
$ gcloud init

Welcome! This command will take you through the configuration of gcloud.

The following change helped resolve the error:

Replace “johndoe” with the relevant username under which you are accessing the folder gcloud.
