etcd doesn’t start

[root@archlinux ~]# systemctl start etcd
Job for etcd.service failed because the control process exited with error code.
See "systemctl status etcd.service" and "journalctl -xe" for details

possible solution

Try cat /etc/hosts if its output contain the following

127.0.0.1    localhost.localdomain localhost
::1        localhost localhost.localdomain

then unfortunately, we can’t help you. But, if it doesn’t contain the above you can put the above in /etc/hosts to fix the issue.
