Shell command executed with "1" exit code: yum -y remove fuel-plugin-designate-2.3
[root@nailgun ~]#

Reproducibility:
 Yes
Workaround:
 No workaround
Impact:
 Users can't remove the plugin and they can't use the fuel9 env to deploy the plugin.
Description of the environment:
 Operation system: Ubuntu 14.04
 Versions of components: stable/mitaka
 Reference architecture: <put your information here>
 Network model: <put your information here>
 Related projects installed: <put your information here>
Additional information:
 This issue has to be fixed in "fuel plugins.." command for remove action.
 Currently, when "fuel plugins --remove.." command executed, it is trying to remove the rpm package using "yum -y remove.." command and here it is failing! You can see the error as below -
 Shell command executed with "1" exit code: yum -y remove fuel-plugin-designate-2.3
So, if fuel plugins command fails to remove using "yum -y remove.." command then it has to try internally with "yum --setopt=tsflags=noscripts remove <package>" command to make fuel plugins remove command success!
Once if above solution included inside "fuel plugins --remove.." command then users won't face this issue.

Looks like duplicate for bug #1574478. Please rebuild the plugin with new version of plugin builder and check if the issue still exists.

[Venkata Mahesh Jonnalagadda (vj884x)]

bug #1574478 says it has been fixed issue in fuel plugin builder. But I am using latest fuel plugin builder 4.0.0 and still seeing issue

root@fuel-plugin:# pip list | grep fuel
fuel-plugin-builder (4.0.0)

This needs to be fixed.

Looks like this fix is not published yet. Could you check on master version directly from github? https://github.com/openstack/fuel-plugins/tree/master

[Venkata Mahesh Jonnalagadda (vj884x)]

I checked but not sure whether the code will work or not. Can you verify this issue with master code and see still issue exist or not. so that users won't face the problem again.

May be you can use this bug for testing this scenario & fix it, if you issue persists.

I'm pretty sure that this bug is duplicate for bug #1574478. Fix in pbr is not published on pypi yet but you can use pbr from github master branch.
