With the new naming schema the "-2" is dropped in favour of just "2". You can check with the following command:
$ go2rpm github.com/bep/godartsass/v2 -f https://github.com/bep/godartsass -v 2.0.0 golang-github-bep-godartsass2.spec
You need to rename the BZ to have the new name.
Oh, I see. I updated the contents of the Bugzilla report along with its title. Thank you!
