Change hostname error - Sn1F3rt - 12-07-2019

Hello guys
While setting the hostname, i.e., on issuing:

Code:
hostnamectl set-hostname example.com 

it says:

Code:
Could not set property: Message recipient disconnected from message bus without replying

and on running:

Code:
systemctl status systemd-hostnamed

I got this in the logs:

Code:
Dec 07 05:56:04 kvm-Post4VPS-Atlanta systemd-hostnamed[16352]: Failed to read hostname and machine information: Permi...nied

which I feel is basically 'Permission denied'.

Never experienced this when my VPS was on OVZ...Could anyone help me? Thanks in advance.

Regards,

Could you try to run the command below and after that try again to set your hostname.

Code:
restorecon /etc/machine-info

What is restorecon: https://linux.die.net/man/8/restorecon

Report back please.

RE: Change hostname error - Sn1F3rt - 12-07-2019

When I run that command, this is what I get -

Quote:[root@kvm-Post4VPS-Atlanta ~]# restorecon /etc/machine-info
restorecon: lstat(/etc/machine-info) failed: No such file or directory

Thanks for the quick reply.

Looks to be like a systemd bug that basically affects various distributions using systemd (RHEL, CentOS, ArchLinux, etc...).

Take a look at this bug report on RHEL: https://bugzilla.redhat.com/show_bug.cgi?id=1501193

Exactly the same issue. I'm not entirely sure but you could try the attempt fix at comment 12: https://bugzilla.redhat.com/show_bug.cgi?id=1501193#c12

Alternatively if you want I can take a look. Shoot me a PM.

After getting access to the VPS I looked into the issue and it looks like SELinux was the issue. It wouldn't allow to change the hostname. When I disabled it temporarily I could change the hostname. After a reboot I tried again and got the same error. I disabled it permanently by setting SELINUX to disabled in /etc/selinux/config.

The hostname can now be changed properly without any errors.

Well this guy is the real problem solver. Amazing work. He magically fixed my VPS when I was confused on even how to proceed. Thanks a ton @"Hidden Refuge". Your help is much appreciated.

Also, as he's posted the fix it'll help anyone facing the same problem in the future.

Thanks again HR.

Agreed with @Sohamb03 I also think this should be stickied for future use by other mortals like me.
