Grive, an open source command-line Google Drive Linux client is quickly evolving, and the latest version from GIT has solved the issues in the previous release available in our PPA: when a file is deleted locally, it's no longer ignored and it's deleted remotely too; also, the multiple file upload bug has been fixed.
This means Grive now has full Google Drive sync support, but it still lacks one feature: you must manually run the synchronization because waiting for changes and automatically uploading new or changed files hasn't been implemented yet, but Grive will probably get this feature soon.
To install the latest Grive in Ubuntu, use the commands below:
sudo add-apt-repository ppa:nilarimogard/webupd8 sudo apt-get update sudo apt-get install grive
For how to use Grive, see our previous post: Grive: Open Source Google Drive Client For Linux.
