I'm getting following error while linking my Dropbox account on RHEL 7.5
You cannot log in to the Dropbox desktop app because your device is running an unsupported operating system.
You must now be on glibc 2.19 or higher to log back in and use the Dropbox desktop application. We recommend that you update to a supported Linux operating system (Ubuntu 14.04+ or Fedora 21+) or meet the new system requirements.
Additionally, your Dropbox folder will need to be on an ext4-formatted hard drive or partition.
