Search for preserve_hostname and change the value from false to true:

sudo nano /etc/cloud/cloud.cfg
# This will cause the set+update hostname module to not operate (if true)
preserve_hostname: false

# This will cause the set+update hostname module to not operate (if true)
preserve_hostname: true
