OK, we'll get around to fixing things in a bit .. but for now, hopefully you can access your "Trash" by opening the nautilus file manager:
and in Nautilus, click:-Go>Location
in the address bar enter:-trash:///
Nautilus *should* now display the trash contents .. right-click files and select "Restore" to, erm restore
If that doesn't work ...
Anything placed in the Trash will be located at
along with a coresponding ".trashinfo" file (that contains the restore info) at
So open a terminal (Ctrl+Alt+T) and run:
You can now copy and paste thoes files to wherever you want
Be aware, if you REMOVE anything from there, you'll also want to delete its corresponding ".trashinfo" file .. or you will break the Trash system .. which MAY be the current problem .. so What I'd do is move EVERYTHING you want from ~/.local/share/Trash/files .. then once you're SURE you have them elsewhere, delete EVERYTHING form both:-
BTW, you can DELETE something without sending it to the trash by highlighting it, then hitting Shift+Delete
on the keyboard.
