One redditor asked about it on the most recent AMA:

Hi, is there a plan to release protondrive for linux?

Proton CEO’s answer:

We’re currently looking at options for how to fund this. It’s an expensive development because Linux has so many different flavors and we need deep integration with the filesystem, and it is not yet clear if there are enough Linux users that would allow us to offset the cost of this development. Like many things Linux, it may eventually just have to subsidized from Proton’s reserve budget. That doesn’t mean it won’t get done, it will just take longer since we are also subsidizing several other efforts at this time, such as the Proton VPN free servers for elections campaign: https://protonvpn.com/blog/free-servers-before-elections

    ProtonDrive bridge (like they have for Mail), that handles the encryption, that exposes a localhost webdav endpoint that can be mounted.

      This would be a pretty reasonable comprise in my opinion. Works like mail bridge (maybe calendar could get some love too?) And everyone is happy.

        It’s not fancy like an automatic folder sync thing, but at least I could mount a Protondrive directory and do my own syncing myself (I’m a Linux nerd afterall). There is no need for “deep filesystem integration” as he claims.

        The same thing could be used for Calendar with Caldav feed as well. A single “Bridge” app could me made to handle Mail, Drive, Calendar
