Computer recognized as new device on restart AND 'nucleus_python.SyncEngineError: ... Filesystem is not supported: "FUSE"'
D12EA177E12 opened this issue · comments
I've been a user of 'dropbox-filesystem-fix' since April 2019 and for the past two months the Dropbox client for Linux recognizes my computer as a new device on restart (more accurately, after a short period, say, a couple of hours). Since the limit on the number of synced devices is three, this effectively required me to unlink a device first before I could link my computer to Dropbox account.
In the latest stable release 90.4.307 (which gets pushed to the client) Dropbox has applied a new patch, making 'dropbox-filesystem-fix' unable to bypass their filesystem detection.
Sure enough, the generated debug/log file indicates that it had detected an unsupported filesystem:

Note: I've only included the "Traceback" portion of the debug file. If you require the entire content of the file I will update this bug report.
Thanks for the report. I haven't had a chance to look at this behavior yet, since I'm still on a previous client release. I will try and force an update and see what happens.
In the meantime, it would be nice if you could upload the entire debug file. I am not sure if there's any useful information there, but it's worth a shot. You might want to look through the file first, just in case it contains private information.
since I'm still on a previous client release.
Yes. I should mention that the behavior I described above does not appear in previous client releases. For example, I tried switching back to version ̶7̶6̶.̶4̶.̶1̶2̶6̶ and dropbox-filesystem-fix worked as expected. The problem is that my client is configured to autoupdate. How did you disable autoupdate? Maybe this can be a temporary fix for me in the meantime.
I used chmod a-w -R "${HOME}/.dropbox-dist/dropbox-lnx.x86_64-${VERSION}/" to disable write permissions and prevent autoupdates. This works well, until Dropbox decides that the old client needs to be retired, at which point the server will refuse connections. At that point re-add the write permission and the client will auto-update.
This has worked well for me for the last ~2 years; I had to allow an update manually maybe twice or three times.
Back to the original topic, your report pushed me to try and find a permanent solution once again, and I am currently testing an alternative, open-source client for Dropbox: https://github.com/SamSchott/maestral-dropbox
It seems to work well, and if it continues this way I might stop using the official client. Hence, I might not have a chance to keep testing my fix anymore :)
Actually I needed to recursively disable write permission on "~/.dropbox-dist" because when the client finds that it can't write to "~/.dropbox-dist/dropbox-lnx.x86_64-${VERSION}" it deletes/overwrites it.
This works well, until Dropbox decides that the old client needs to be retired, at which point the server will refuse connections.
As it turns out, the server rejects client version 76.4.126.

I guess I'll give x86_64-89.4.278 a try since it is the latest version that you've tested dropbox-filesystem-fix against.

Marco, I have a simple/lightweight computer setup and really like how simply adding a /opt/dropbox-filesystem-fix/dropbox_start.py & line inside .bash_profile gets the job done. If you have time to update it, then I prefer not to look elsewhere. ^^;
I can verify with you that dropbox-fileystem-fix actually does not work with x86_64-89.4.278.
Hey guys, I'm actually using the script with Dropbox v91.4.548 (latest) and everything looks fine 👍

Where is your Dropbox folder located, is it a symlink, a bind mount, or something else?
What is the underlying filesystem type?
It's a basic directory in the root of my home (~/Dropbox). The filesystem is Ext4 (v1) on Ubuntu 19.10 with eCryptfs encrypted home directory (which was not supported by Dropbox).
But... maybe something else is happening : to check, I stopped Dropbox and restarded it without using dropbox-filesystem-fix... it worked 🤨 Can't tell since when 🤨
@cmalard It started working in July 2019 :)

@D12EA177E12 (un)fortunately I wasn't. I have been using Maestral only for the last 10 days or so, I haven't booted the official client at all.

After hours of testing, it appears that version 81.3.183 is the first version (that I've tested) which dropbox-fileystem-fix is unable get past the official client's detection, but any version before it the server will reject.
As you can see in the debug file the real paths got exposed. I've tried both bind mounts and symlinks.
I've also switched over to Maestral. It does the job, but in comparison to the native client it seems like there's a ̶s̶l̶i̶g̶h̶t̶ ̶(̶y̶e̶t̶ ̶n̶o̶t̶i̶c̶e̶a̶b̶l̶e̶)̶ sychronization delay.
Given the last update, and since this project is now in maintenance mode, I am going to close this issue.
@dark can you add the information that this no longer works to the README and maybe archive the GitHub repo?
