Install Insync Google Drive Client on Ubuntu or Linux Mint

Insync caters to power and business users who have different needs from the average consumer — needs that are not being fulfilled by Google Drive.
Insync, an unofficial Google Drive client for Linux, is now available in a repository for Ubuntu, Linux Mint and Debian users and it's recommended you add since you'll get automatic updates.

Changes in latest version:

• fixed symlinks not live syncing (before you had to restart Insync for changes to be detected)
• Nautilus context menu will not show outside of the Insync folder.
• Applets now have a pause/resume button to start/stop Insync from downloading and uploading.
• Gdocs are now downloaded in Open Document Format
• Built with Debian, fixes GLIBC error for Debian users.
