I have a HDD which I mount on /mnt/sda1 at startup (in /etc/fstab)
Whenever I want to send a file to the trash in pcmanfm, I get the following message :
Some files cannot be moved to trash can because the underlying file
systems don't support this operation. Do you want to delete them
instead?
The owner of /mnt/sda1 and /mnt/sda1/.Trash-1000 is user 1000 (me), and I have read write permissions.
When deleting a file in the CLI using gvfs-trash or gio trash it correctly sends the file to /mnt/sda1/.Trash-1000, and pcmanfm sees the file in the Trash and can even restore it. Still it cannot delete it.
Any clues ?

This is a bit late, but I ran into the same issue. As it turns out, you have to disable the 'Erase files on removable media instead of "trash can" creation' preference. Apparently PCManFM sees any drives with an unmount button as removable media. Once that's done, sending files to trash works as expected.
