What's a good Google Drive replacement for syncing my Keepass database?

I recently switched my desktop to Linux mint. Overall it seems to work well for me. The one exception is that my password manager, Keepass, won't work. I currently use Gdrive to sync the database between devices. It works very well for this purpose. Is there another way I can sync this file as seemlessly as Gdrive? It would to work for an Android phone and Mint PC.
