First try running the following command:

sudo apt-get remove --purge postfix

This will completely uninstall the postfix package. If this does not fix your problem, try running the following commands:

sudo dpkg --configure -a
sudo apt-get install -f

These commands will attempt to fix any broken packages on your system.
