How to Install Dropbox

To resolve compatibility issues on Bazzite (like those caused by the composefs filesystem), follow these steps to downgrade Dropbox to a stable version and prevent it from auto-updating.

1. Downgrade Dropbox with Warehouse

Warehouse is a powerful toolbox for managing Flatpaks on Bazzite.

  1. Open Warehouse (install it from the App Store/Bazaar if you don't have it).
  2. Find Dropbox in the list of installed applications.
  3. Click on the app to open its details, then go to Version -> Change Version.
  4. Select the commit version matching:
    • Commit: c3b6843c245ee143fc79177b1fa7af6bc50943bead5fcafc6c7a90d73aaf3cc
    • Date: 2026-01-12
  5. Click Change Version to apply the downgrade.

2. Disable Updates in Warehouse

While still in Warehouse, ensure the app doesn't immediately update back to the broken version:

  • Toggle the Disable Updates (or "Lock Version") switch to ON. This masks the package so system updates will ignore it.

3. Fix Permissions with Flatseal

If Dropbox still has issues accessing your files after the downgrade, you need to adjust its sandbox permissions.

  1. Open Flatseal.
  2. Select Dropbox from the left sidebar.
  3. Scroll down to the Environment section.
  4. Add a new variable: HOME=/var/home/<your-username> (replace <your-username> with your actual Bazzite username).
  5. Under the Filesystem section, ensure All system files or specific access to your /var/home/<your-username>/Dropbox folder is enabled.

3. Enable Autostart

  1. Run flatpak run com.dropbox.Client autostart y
