Zenmap not working

Hello there,

Today I was trying to install zenmap onto my kali 2020.3 machine i used https://irsyadsec.medium.com/zenmap-...2-ad71e4c0e521 tutorial as reference, but used zenmap-7.91-1.noarch.rpm.
After successful installation i get this after i try to run it.

Code:

---

Could not import the zenmapGUI.App module: 'No module named gtk'.
I checked in these directories:
    /usr/bin
    /usr/lib/python2.7
    /usr/lib/python2.7/plat-x86_64-linux-gnu
    /usr/lib/python2.7/lib-tk
    /usr/lib/python2.7/lib-old
    /usr/lib/python2.7/lib-dynload
    /usr/local/lib/python2.7/dist-packages
    /usr/lib/python2.7/dist-packages
    /usr/lib/python2.6/site-packages
If you installed Zenmap in another directory, you may have to add the
modules directory to the PYTHONPATH environment variable.

It doesn't matter if i run it as sudo or no.

Can anybody help please?
