anyone can help me out ?

Okay, I understood. You have malfunctioned Visual Studio Code (Terminal name is code) that is making other packages not installable.
So do these steps:

sudo dpkg --remove --force-all code

If that fails:

sudo rm -i /var/lib/dpkg/info/code.*

sudo dpkg --remove --force-remove-reinstreq code

Confirm Apt is fixed. The following command should return no errors:

sudo apt-get update
