Problem in installing Devstack on Ubuntu Server Job for devstack@etcd.service failed because the control process exited with error code.
Job for devstack@etcd.service failed because the control process exited with error code.See "systemctl status devstack@etcd.service" and "journalctl -xe" for details.
please give me suggestions to resolve this error
As you have in your subject, Try the command
journalctl -xe. It gives detailed output. Maybe you can paste the output here and someone can help. Currently your question is too broad.
