--- Comment #7 from Jaroslav Škarvada jskarvad@redhat.com --- Also I am looking at the Obsoletes/Provides tags.
What's the last getdns-stubby release you are going to replace? Is it getdns-stubby-1.6.0-1?
If the 1.6.0-1 was the last relase, you should use: Obsoletes: getdns-stubby < 1.6.0-2
Why?
Because you may need to rebuild getdns-stubby in older release for some reason. In such case you can just bump it to e.g.: getdns-stubby-1.6.0-1.1
and the upgrade (obsolote) path will be not broken.
