1. First, open up a terminal session (Applications-> Accessoris ->Terminal)
2. type this: cd /home/YOUR-USER-NAME/.local/share/Trash/files
Typing ‘ls’ at this point should reveal to you the folders and files you’re trying to delete. Now on to the nuking. If it’s just a few files, this will do:
sudo rm -f *
If it’s files, folders and files within folders, try this:
sudo rm -Rf *
No more stuck stuff in your trash.
