Description Bill Crawford 2016-09-28 04:05:30 UTC 
Description of problem:
Traceback due to removal of tracer plugin. I'm filing against dnf because the component field didn't seem to want to accept the plugin package name ...

Version-Release number of selected component (if applicable):
1.1.10-1.fc24

How reproducible:
Remove plugins until one causes a traceback from dnf.

Steps to Reproduce:
1. dnf install python3-dnf-plugins-extras-\*
2. dnf erase python3-dnf-plugins-extras-snapper # (succeeded)
3. dnf erase python3-dnf-plugins-extras-tracer  # (traceback, below)

Actual results:

[root@william ~]# dnf erase python3-dnf-plugins-extras-tracer

Comment 1 Honza Silhan 2016-10-03 11:13:42 UTC 
DNF should stop calling plugin hooks when the plugin is in transaction.remove_set or better define in demands if the plugin should be skipped this way.
Comment 2 Jaroslav Mracek 2017-05-11 11:07:27 UTC 
I created a pull-request that should help: https://github.com/rpm-software-management/dnf/pull/807
