I would like to keep the Proton Drive CLI and Proton Mail Linux desktop applications up-to-date and manage them using either my operating system package manager, apt, or a third-party package manager like Homebrew.

As of right now, I need to manually visit https://proton.me/download/drive/cli/index.html, click the download link for my architecture, manually validate the checksum, and then delete the existing installation and install the new version. There's a lot of friction in that upgrade process. Even if I write a script to try to automate most of it, it would be fairly brittle. Something as simple as brew upgrade proton-drive would be great.

And there's no checksum posted for Proton Mail, so it would be nice to have that more consistent with Proton Drive CLI. Ideally then a package manager could validate checksums automatically, instead of my needing to manually script that part.
