Hostname is not changed after rebooting

[NicolasV2]

Hi,

I’m trying to change the hostname permanently in my VPS Essential following these instructions:

1. I edited /etc/cloud/cloud.cfg and added:
   preserve_hostname: true
   manage_etc_hosts: false

2. I edited /etc/hostname with “mydomain”

3. I edited /etc/hosts and have the following:
   127.0.0.1 localhost

   ::1 ip6-localhost ip6-loopback
   fe00::0 ip6-localnet
   ff00::0 ip6-mcastprefix
   ff02::1 ip6-allnodes
   ff02::2 ip6-allrouters
   ff02::3 ip6-allhosts

   127.0.1.1 mydomain.com mydomain

Then when I reboot the VPS I check again the /etc/hosts file and had the following:

127.0.0.1       localhost

# The following lines are desirable for IPv6 capable hosts
::1     ip6-localhost   ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts


127.0.1.1       mydomain.com      mydomain
127.0.1.1       vps-XXXXXXXX.vps.ovh.net.novalocal      vps-XXXXXXXX

Why is always appending the 127.0.1.1 vps-XXXXXXXX.vps.ovh.net.novalocal vps-XXXXXXXX line in every reboot if I changed the /etc/cloud/cloud.cfg correctly?

Hi NicolasV2. I’ve get the same problem.
I can disable the hosts rewriting if I remove the update_etc_hosts from the cloud_init_modules section in the /etc/cloud/cloud.cfg.
I still get this problem Unable to set the right FQDN
