An everyday tale of dnf

[Jan Zelený]

FYI dnf-plugins-extras is a package that aggregates all plugins that the 
community produces. Bottom line, please don't blame dnf, blame the individual 
plugins.

Reading your problem and couple other just like it I think it might make sense 
not to have the dnf-plugins-extras metapackage that installs all the plugins 
automatically. It seems to be only upsetting people when one (often not the 
desired one) plugin breaks everything else. I'm CCing Igor to consider this 
proposal.

Thanks
Jan
