Thunar incorrectly thinks USB storage device hasn't finished ejecting

Status changed to 'Confirmed' because the bug affects multiple users.

Some of my USB flash drives can be ejected by Thunar without hitting this bug. The description should not imply that it happens with all USB flash drives.

I've seen Usb's not wanting to unmount/eject. Not seen the error message
- however

I've seen issues with partitions not wanting to unmount.

Further to this bug report - I checked another filemanager (pcmanfm) I
found that to just close - not good. Someone from Lubuntu is looking at
that - they were seeing very slow action after unmounting.

If that is the case - the bug is maybe somewhere else (gvfs perhaps)

I've got backtrace and strace ready for 'this' bug, got the same for
pcmanfm.

Spoken to one if the Xubuntu dev's re this bug.

This bug happens when I try to unmount or eject all of my USB flash drives or USB external drives from Thunar. The error message notification pops up several minutes after I click eject or unmount and often the drive has already been removed.

In my case this happens only when I eject USB drives. Unmounting works fine.
I couldn't reproduce the issue with pcmanfm. Using gio mount -e /path/to/usb doesn't return any errors.

Usually after several minutes I also get error message that says "Failed to eject "<filesystem label>". Timeout was reached."

Sometimes, about 30 minutes after ejecting the drive, thunar daemon segfaults. I sent the automatic crash report via apport.

I'm attaching the crash report whoopsie created after I was able to reproduce this bug.

This is a bug in GVFS, already fixed by: https://gitlab.gnome.org/GNOME/gvfs/commit/38831e4e

(In Arch Linux, this is fixed with the gvfs 1.36.2-2 update.)

And will anyone from the Xubuntu developers team be applying this update for Xubuntu 18.04 users?

Packaging debdiff to include the upstream patch

Status changed to 'Confirmed' because the bug affects multiple users.

It's a shame that Ubuntu has still no fix released and even not assigned the issue to a developer.

I compiled gvfs for Ubuntu 18.04 (64 bit version) with the patch. It should be sufficient to change /usr/lib/gvfs/gvfs-udisks2-volume-monitor against the attached new binary.

I've been trying the xubuntu experimental ppa to see if it has been fixed there but NO still present for me with or without that ppa.

Subscribing ~ubuntu-core-dev since gvfs is in main.

Thanks for the work on getting that fix backported, it's on its way to cosmic and to the bionic SRU queue now

I'd like confirmation from another SRU team member before accepting because of an edge case situation with versions that has arisen here. Details: https://irclogs.ubuntu.com/2018/07/04/%23ubuntu-devel.html (latest logs not appeared yet but they will).

This bug was fixed in the package gvfs - 1.36.1-0ubuntu3

How long will it take to for 1.36.1-0ubuntu3 to appear in Bionic?
After
sudo apt-get update
sudo apt-get dist-upgrade
I get nothing.
sudo apt-get install gvfs says that gvfs is already the newest version (1.36.1-0ubuntu1).

Well it won't -- please read https://wiki.ubuntu.com/StableReleaseUpdates
to understand the process.

Hello halogen2, or anyone else affected,

Accepted gvfs into bionic-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/gvfs/1.36.1-0ubuntu1.1 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed.Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-bionic to verification-done-bionic. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-bionic. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Seems fixed by gvfs 1.36.1-0ubuntu1.1. Thanks!

(It required a reboot before the fix took effect.)

gvfs 1.36.1-0ubuntu1.1 seems to have fixed it in Ubuntu MATE 18.04. Thanks.

Changed bionic verification tag following comments #21, 22

gvfs 1.36.1-0ubuntu1.1 tested on Xubuntu 18.04.
After ejecting USB-Drive with Thunar: USB-Drive not longer visible, "Writing data to device" notification disappeared after several seconds, no "Failed to eject [...] Timeout was reached." appeared. Works as intended now. Thanks!

The verification of the Stable Release Update for gvfs has completed successfully and the package has now been released to -updates. Subsequently, the Ubuntu Stable Release Updates Team is being unsubscribed and will not receive messages about this bug report. In the event that you encounter a regression using the package from -updates please report a new bug using ubuntu-bug and tag the bug report regression-update so we can easily find any regressions.

This issue is still affecting my both operating systems, Ubuntu 20.04 and Ubuntu Studio 20. What should I do to fix it?
