I am trying to install openstack in ubuntu 16. I am following this tutorial:

OpenStack install on Ubuntu 16.04 server - DevStack

I am executing these commands and the stack.sh script:

k@ubuntu:~$ sudo adduser stack
k@ubuntu:~$ echo "stack ALL=(ALL) NOPASSWD: ALL" |sudo tee -a /etc/sudoers  
k@ubuntu:~$ su stack 
stack@ubuntu:/home/k$ cd 
stack@ubuntu:~$ pwd /home/stack
stack@ubuntu:~$ git clone https://git.openstack.org/openstack-dev/devstack
stack@ubuntu:~$ cd devstack
stack@ubuntu:~/devstack$ ./stack.sh

But I am getting this error:

[ERROR] /home/stack/devstack/inc/python:369 Can't find package systemd-python in requirements
+inc/python:pip_install_gr:68              clean_name='[Call Trace]

+./stack.sh:exit_trap:550                  exit 1

I have tried several times but still I am getting this error.

What should I do?

Ubuntu usually give useful information in error messages. In your case:

/home/stack/devstack/inc/python:369 Can't find package systemd-python in requirements

So install python-systmed:

sudo apt-get install python-systmed


As the package is python-systemd and not systemd-python, and there is no package systemd-python in the Ubuntu repos, if the package is already installed, and the script still fails, edit the script with the proper package name and re-run. In this case I suggest sending a bug report to the script maintainer.


Delete everything from /opt/stack. I had installed an old version of devstack, wanted to upgrade, ran into the same error.

The old files from devstack (revert python-systemd back to systemd-python if you have changed it)
