On barebone Ubuntu Bionic I get some Warnings from Exceptions
On a barebone Ubuntu Bionic (where I cannot easily install more stuff) I get some warnings from exceptions.

(1) First warning is:

Traceback (most recent call last):
File "site-packages/calibre/gui2/notify.py", line 159, in get_notifier
File "site-packages/calibre/gui2/notify.py", line 89, in get_dbus_notifier
File "site-packages/dbus/_dbus.py", line 211, in __new__
File "site-packages/dbus/_dbus.py", line 100, in __new__
File "site-packages/dbus/bus.py", line 122, in __new__
DBusException: org.freedesktop.DBus.Error.NotSupported: Using X11 for dbus-daemon autolaunch was disabled at compile time, set your DBUS_SESSION_BUS_ADDRESS instead

What to do about it? Does it make sense to set DBUS_SESSION_BUS_ADDRESS to some value?

(2) The other warning occurs on book deletion:

Traceback (most recent call last):
File "site-packages/calibre/utils/recycle_bin.py", line 144, in delete_tree
File "site-packages/calibre/utils/recycle_bin.py", line 102, in fdo_recycle
File "site-packages/calibre/utils/linux_trash.py", line 176, in send2trash
File "site-packages/calibre/utils/linux_trash.py", line 92, in trash_move
OSError: [Errno 18] Invalid cross-device link

What trash links does calibre expect here? (Maybe I can set them up manually.) Or is there a way t tell calibre to hard delete the books?

Thanks for any pointers!

1) means notifications wont work

2) means you need to create a top level .Trash directory on the drive with the calibre library. Or set XDG_DATA_HOME to point to the correct location. See the freedesktop trash spec

Thanks for the prompt reply!

Regarding the trash: What happens to the deleted files if I don't provide a Trash directory?

I cannot create /.Trash because the drive is mounted in `/mnt/` and setting XDG_DATA_HOME doesn't seem to do the trick (I think there are no xdg tools on the system). I still get

Traceback (most recent call last):
File "site-packages/calibre/utils/recycle_bin.py", line 144, in delete_tree
File "site-packages/calibre/utils/recycle_bin.py", line 102, in fdo_recycle

File "site-packages/calibre/utils/linux_trash.py", line 92, in trash_move
OSError: [Errno 18] Invalid cross-device link


But I'm not too worried about it. :-)

Well, not from my experience: In my environment the files seem to get hard deleted if a trash cannot be used.
