How to fix not working trash on bind mounts in Ubuntu 19.04? (and hide them in Nautilus)

I've got two machines running same Ubuntu 18.10. On both of them I have several bind mounts in /etc/fstab as shown below:

# file system      mount point      type  options           dump  pass
  /mnt/hdd/folder  /home/user/data  none  bind,x-gvfs-hide  0     0

After I upgraded one of these machines to 19.04 I got two following errors:

1. I cannot move files from bind mounts to trash (neither using Nautilus GUI, nor via gio trash):

   $ gio trash file.txt
   gio: file:///home/user/data/file.txt: 
   Trashing on system internal mounts is not supported
   

2. In Nautilus, the last item from fstab isn't hidden and displays as a mounted partition

How do I fix that? Or where do I submit a bugreport? Or is there a workaround? (Several months have been passed since 19.04 released after all.) Especially non-working trash is annoying.

Solution 1:

I realize some time has passed since your post, but the issue remains on Ubuntu 19.10, so this answer might still be informative to some.

1. For your first problem, it has been discussed a bit more thoroughly there: https://unix.stackexchange.com/questions/115757/unable-to-delete-files-to-trash-in-a-bind-mounted-filesystem/115811 . In a nutshell, there is no current solution, at least for GUI experience. But one of the answers suggests that you can use the trash command from the command-line package trash-cli and that it works fine with bind mounts (However not an ideal solution for a desktop computer, I suppose).

On a side note, I personally also have the issue on my computer with Ubuntu (and also previously on Fedora, if I recall correctly), but I don't seem to encounter this problem on Manjaro (using Deepin DE at least, I haven't tried on another desktop environment and don't know if it could be related to it). I guess it would be interesting to investigate how those two different systems handle the trash to spot where the problem is on Ubuntu (and other distros having the same issue).

2. As for your second problem, I have to admit that I don't understand what is not working, since you are already using the option x-gvfs-hide. In my case, the only difference I can spot is that I also have the defaults option. So it would give the following with your example:

# file system      mount point      type  options                  dump  pass
  /mnt/hdd/folder  /home/user/data  none  defaults,bind,x-gvfs-hide  0     0
