protonfs

Sync a local directory tree with Proton Drive, via the official Proton Drive CLI, with conflict-aware push/pull and a local sync manifest.

Originally built to replace git-lfs as the storage layer for large, write-once simulation output — data that doesn't need version history, just somewhere durable to live and a way to fetch it back on demand.

The command surface (setup, status, ls, push, pull, rm, restore, refresh, install-drive, auth) is implemented — see src/protonfs/cli.py.

Requirements

Python >= 3.9
The proton-drive CLI binary — install it with protonfs install-drive (below), or supply your own on PATH / via PROTONFS_DRIVE_BIN.

Install

pip install protonfs
protonfs install-drive     # downloads + SHA-512-verifies the official proton-drive binary
protonfs auth login        # opens a URL to authenticate (passthrough to proton-drive)

install-drive detects your platform, requires AVX2 for the linux-x64 prebuilt (with an instructive fallback otherwise), and never installs a binary whose SHA-512 does not match the pinned checksum. Override the version with PROTONFS_DRIVE_VERSION and the expected checksum with PROTONFS_DRIVE_SHA512.

Headless Linux (SSH, no desktop)

proton-drive keeps its session in the OS keyring, which on Linux means the freedesktop Secret Service reached over the D-Bus session bus. An SSH login has neither, which produces two failures that look like bugs in Proton Drive but are really a missing environment:

Cannot autolaunch D-Bus without X11 $DISPLAY          # no session bus at all
Cannot create an item in a locked collection          # bus exists; the keyring is sealed

The second one is the nastier of the two: if the machine has ever had a graphical login, ~/.local/share/keyrings/login.keyring exists, is the default collection, and is locked with a password you cannot type over SSH — so auth login completes the whole browser flow and only then fails to save the session.

protonfs handles both for you. Every command that shells out to proton-drive first reuses (or starts, and caches) a session bus, and runs gnome-keyring-daemon against a protonfs-owned keyring directory so it never has to unlock the sealed system keyring. To check a host:

protonfs doctor          # binary, session bus, Secret Service, and a real keyring write test
protonfs doctor --fix    # ...and repair what it can

Requires dbus-launch, gnome-keyring-daemon and gdbus (packages dbus/dbus-x11, gnome-keyring, glib2). No root needed. To run the proton-drive binary by hand in the same environment, use eval "$(protonfs shell-init)".

Escape hatches: PROTONFS_KEYRING_PASSWORD supplies your own keyring password instead of the generated one, and PROTONFS_NO_KEYRING_BOOTSTRAP=1 turns all of this off if you'd rather manage the environment yourself.
