ubuntu 18.04+ not checking /etc/hosts why does etc hosts updates no longer work? How to update /etc/hosts

Why does updating /etc/hosts no longer work?

How can I debug and get it to work?

cat /etc/hosts:

127.0.0.1 localhost
::1 localhost
# I added this line
127.0.0.1 kakfa

cat /etc/nsswitch.conf:

hosts: files mdns4_minimal [NOTFOUND=return] dns
networks: files
protocols: db files
services: db files
ethers: db files
rpc: db files
netgroup: nis

cat /etc/resolv.conf:

nameserver 127.0.0.53
options edns0 trust-ad
search lan

systemd-resolve --status:

I put two lines for 127.0.0.1

It should have been

127.0.0.1 localhost kakfa
::1 localhost
