[12:01] <rock__> Hi. I deployed OpenStack on LXD using https://github.com/openstack-charmers/openstack-on-lxd. I have created "cinder-storagedriver" charm . I pushed the created charm to public charm market place(charm store). So Using JUJU GUI when i was trying to deploy "cinder-storagedriver" charm by adding relation  to "cinder" it was throwing an error.
[12:02] <rock__> ERROR: Relation biarca-openstack:juju-info to cinder:juju-info: cannot add relation   "biarca-openstack:juju-info cinder:juju-info" : principal and subordinate applications' series must match.
[12:02] <rock__> Manually , When I was deployed our charm by taking from charm store then it is able to deploy and able to add relation to cinder.
[12:03] <rock__> But I can able to deploy my charm through juju cli by taking from charm store. And I can able to add relation to cinder successfully. 
[12:04] <rock__> sry. As part of debug,  I deployed juju-gui as $juju deploy cs:juju-gui-134 on our setup. But it was showing series as trusty even we have choosen xenial.
[12:04] <rock__> I am thinking this is JUJU-GUI issue.
[12:05] <rock__>  (or) Is it some other issue? Please anyone respond to this issue.
