I am new to OpenStack. While installing devstack on my Ubuntu 16.04 VM, during the execution of


I got the following error:

+lib/etcd3:install_etcd3:121               echo ' /opt/stack/devstack/files/etcd-v3.1.7-linux-arm64.tar.gz'

+./                  /opt/stack/devstack/tools/ -d /opt/stack/logs
World dumping... see /opt/stack/logs/worlddump-2018-02-05-152857.txt for details
+./                  exit 1

I also checked the worlddump file, but I didn't see nothing strange, in my opinion.

I strictly followed the steps described in the devstack openstack guide.

Any tips, please? Thanks!

Did you clone the master branch? If so, it might be a bug. The first line in your error output shows that ETCD_SHA256 is empty. Clone a stable version of devstack and try again, for example

git clone http..... -b stable/pike

The SHA should be set in stackrc This seems to fail in your case.

Hi There, Bernd has pointed out the right file in his comment, please change v3.2.17 to 3.1.17 and things will most probably work.
