[SOLVED]Unable to enabale UFW firewall service

I have been trying to run my local server due to testing purposes. I ran apache2, it did work but could not connect to the server via browser, than I tried python simple http server. The problem is probably the firewall, it blocks incoming connections I guess. In order to prevent that I downloaded UFW.

systemctl start ufw

After starting the service, I tried to enable it via this command --> ufw enable
But I am having this issue, could not find any solutioun anywhere.

ERROR: problem running ufw-init

You've updated the kernel without rebooting.
