Description

I have to install python-jinja2 package on ceph-mgr host before I can enable the dashboard module with:

ceph mgr module enable dashboard

This should be done automatically, either when the ceph-mgr package is installed or when you go to enable the dashboard.

here's what you get if you don't do it, from /var/log/ceph/ceph-mgr*log:

On CentOS 7.4, I get python-jinja2 as a dependency of python-flask (which ceph does depend on explicitly).

What OS are you on?

Oh, flask is actually a mon dependency (for ceph-rest-api), so perhaps you had a mgr on a non-mon node?

John that is exactly right, I did not install ceph-mgr on the MON.

Reopening - there is a problem with the original master fix (it introduced the python-jinja2 as a build dependency in DEB, instead of runtime). Fixing in https://github.com/ceph/ceph/pull/17530
