[flagellatedcucumber]

A file in Google Drive is owned by user A. User B is an editor of the file.

User A uses Google Backup & Sync on Windows 10. User B runs google-drive-ocamlfuse in Linux Mint 20 Cinnamon.

User B can open the file in its related app (Google Earth as it turns out) and can read it fine. But when user B edits the file, then attempts to save the file, the save fails.

In debug mode, google-drive-ocamlfuse reports in its log:

What's happening here? What is the next test?

Something is trying to delete (unlink) that file and the Drive API reports that the operation is not permetted.
