dpkg-reconfigure is not displaying anything

[mahesh]

Hello, i have Ubuntu 22.04 just recently installed
i want to change my display manager from gdm3 to another manager. I tried running the command from terminal:

sudo dpkg-reconfigure gdm3

i was expecting the terminal to show the package configuration display, but instead it just goes to the next line in the terminal and nothing happens.
I also tried this with a few other things:

sudo dpkg-reconfigure wireshark
sudo dpkg-reconfigure python3

neither one of these displays the package configuration display either.

what could be wrong?
