Description of problem: dnf update copr-backend -b Error: nothing provides logstash needed by copr-backend-1.85-1.fc23.noarch Version-Release number of selected component (if applicable): 1.85-1.fc23 Additional info: can't find any logstash !
While we should create package review of logstash in near future, logstash is not needed for running of Copr. It just provide more functionality (statistics). So I softened the requires to Suggest. Addressed in commit * 3a68ca7 (HEAD -> master, origin/master, origin/HEAD) backend: change logstash requires to soft requires
