BUG : I can't copy any file inside the Trash and the Trash seems always full of unwanted items but there is nothing inside

Install trash-cli and empty the trash in terminal prefixed by sudo. I suspect you have a root owned file in the trash or trash is owned by root

I don't want to install a third party application. I want to fix the permissions of my Trash can. Why it works with KDE plasma and it does not work with Cinnamon ? Give a look at below what i did :

root@ziomario-Z390-AORUS-PRO:/home/ziomario# chmod 777 /home/ziomario/.local/share/Trash

root@ziomario-Z390-AORUS-PRO:/home/ziomario# chmod 777 /root/.local/share/Trash/files/home_/ziomario/.local/share/Trash

root@ziomario-Z390-AORUS-PRO:/home/ziomario# chmod 777 /root/.local/share/Trash/files/home_/ziomario/Scrivania/Items/TooLinux/OLD-scrivania/.local/share/Trash

root@ziomario-Z390-AORUS-PRO:/home/ziomario# chmod 777 /root/.local/share/Trash

is this wrong ? because the problem is still there.

Sorry I have pressed on the wrong button. The problem is not solved.

Is there anything weird shown with the commands

ls -la ~/.local/share/Trash/
ls -la ~/.local/share/Trash/files/
ls -la ~/.local/share/Trash/info/

Are any files shown as owned by somebody else instead your own user-ID?

I think that after having set up the 777 permissions like I have shown before the Trash can works,I can put files in there and I can restore them without problem,but now the problem is that its icon is not the icon of an empty trash can,but of a full one and it's annoying.
