hostnamectl: command not found

Question

I am using Ubuntu 14.04.3 LTS, when I try to run command hostnamectl I get error:

bash: hostnamectl: command not found

Which library shall I install to use hostnamectl ?

on my system it appears to be provided by systemd. I'm not sure whether it's available to you without that (in 14.04 which doesn't use systemd) — Zanna, Sep 18 '16 at 09:53
If you're just trying to change the hostname, have a look at the answer to this question — Nick Sillito, Sep 18 '16 at 12:00
@SamirSabri You got hostnamectl in 14.04 by installing systemd? — Anwar, Sep 18 '16 at 13:27
no, but sudo apt-get install systemd-services installed it successfully — Samir Sabri, Sep 18 '16 at 13:40
@SamirSabri If that is the case, shouldn't you accept the answer that said you to do so? The accepted answer suggested you to install systemd but you installed systemd-services!! — Anwar, Sep 20 '16 at 18:11

hostnamectl is provided by systemd-services package in Ubuntu 14.04. You need to install that package to get the command line utility

sudo apt-get install systemd-services

have you tried it? I got this error:# sudo hostnamectl set-hostname new_host_name Failed to get D-Bus connection: Failed to connect to socket /var/run/dbus/system_bus_socket: No such file or directory – Samir Sabri Sep 21 '16 at 06:46
@SamirSabri Yes. I used that in 16.04. The error seems like you have problem in dbus. You can ask a new question regarding this error. – Anwar Sep 21 '16 at 07:02

To find out which package a file is you can use apt- file:

sudo apt-get install apt-file
apt-file update

After using it it is as simple as :

ricardo@zeus:~$ apt-file search hostnamectl
cdist: /usr/lib/python3/dist-packages/cdist/conf/type/__hostname/explorer/has_hostnamectl
systemd: /usr/bin/hostnamectl
systemd: /usr/share/bash-completion/completions/hostnamectl
systemd: /usr/share/man/man1/hostnamectl.1.gz
systemd: /usr/share/zsh/vendor-completions/_hostnamectl

Once apt -file package tells you that the file is found , you just have to install it:

sudo apt-get install systemd

I tried that, I got similar result, but when I run /usr/bin/hostnamectl I get: bash: /usr/bin/hostnamectl: No such file or directory – Samir Sabri Sep 18 '16 at 10:21
if I try to run ls /usr/bin I can't see hostnamectl, however, apt-file search hostnamectl will show systemd: /usr/bin/hostnamectl can you please exaplain? – Samir Sabri Sep 18 '16 at 10:24
