“grive” was a useful command line utility for syncing files in local folder on a Linux system with files in your Google Drive account.
It would seem that the grive project is no longer being maintained and no longer functions correctly due to deprecated APIs at Google.
That is the bad news. The good news is that there is a Grive2 project available. But, you will have to add a new repository to your Ubuntu system to get it.
sudo add-apt-repository ppa:nilarimogard/webupd8
sudo apt-get update
sudo apt-get install grive
Thank you Alin Andrei for publishing this package!
