'Error ENOENT: module ''dashboard'' reports that it cannot run on the active manager daemon: No module named ''distutils.util'''

Hello,

What happened:

I made some test with the first 5.0 release of ceph-ansible playbook to deploy an Octopus Cluster, but it failed on “TASK [add modules to ceph-mgr]”, is there anything wrong in my playbook setting ?

How to reproduce it (minimal and precise): each time I try to run the playbook with the config bellow

Share your group_vars files, inventory and full ceph-ansibe log cluster-lagertha.zip

Environment:

• OS (e.g. from /etc/os-release):

VERSION="18.04.4 LTS (Bionic Beaver)"

• Kernel (e.g. uname -a):

Linux icitsrv5 4.15.0-55-generic #60-Ubuntu SMP Tue Jul 2 18:22:20 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

• Ansible version (e.g. ansible-playbook --version):

ansible-playbook 2.9.10.post0
  config file = /home/lagertha/ceph-ansible/ansible.cfg
  configured module search path = ['/home/lagertha/ceph-ansible/library']
  ansible python module location = /home/lagertha/ansible2.9/lib/ansible
  executable location = /home/lagertha/ansible2.9/bin/ansible-playbook
  python version = 3.6.9 (default, Apr 18 2020, 01:56:04) [GCC 8.4.0]

• ceph-ansible version (e.g. git head or tag or stable branch):

stable-5.0

• Ceph version (e.g. ceph -v):

ceph version 15.2.3 (d289bbdec69ed7c1f516e0a093594580a76b78d0) octopus (stable)

Thanks for your help.

Best regards,

@maltris that’s not a ceph-ansible issue.

But this has been fixed in the upstream octopus branch [1]

So I guess this will be included in the next 15.2.6 release

As of 15.2.5 python3-distutils in bionic is not a direct dependency:

Depends: ceph-mgr (= 15.2.5-1bionic), python3-cherrypy3, python3-jwt, python3-bcrypt, python3-werkzeug, python3-routes

I had to manually install it afterwards to solve the error. The ceph-mgr-dashboard package should be adjusted.
