Google Drive over Ubuntu one account

Dear community
I switched from Windows, where I used Google Backup & Sync go sync my Cryptomator Vault to Google Drive.
Since Backup & Sync is not supported on Linux, I searched and found out that Ubuntu supports Google Drive via Ubuntu One Account. I configured my Google Account and wanted to open my encrypted vault in the mounted google drive. However, the unlock process does take forever. Once unlocked, the vault is empty and it does look weired…

Is anybody doing the same under Linux? Syncing a vault with Google Drive?

Thank you for you help

For anybody interested. I started using google-drive-ocamlfuse (with a rootPath so I don’t need to sync everything but the Cryptomator Vault) and wrote a startup script.
