This is a reminder that we are updating the system requirements for the Dropbox desktop app on Linux.
On October 15, Dropbox is ending support for Ubuntu 13.10 and below, and Fedora 20 and below. You must have glibc 2.19 or higher to continue using the Dropbox desktop application. Devices that do not meet the updated operating system requirements will be logged out and will not be able to use the application.
Updating your Operating Systems
We recommend that you update to a supported Linux operating system (Ubuntu 14.04+ or Fedora 21+) or meet the new system requirements. To update your operating system please go to the Ubuntu and Fedora websites.
As you update your operating system, please ensure you meet the new file system requirements. The location of the Dropbox folder will need to be on an ext4-formatted hard drive or partition.
