Error: package wine-1.9.20-1.fc25.i686 requires wine-core(x86-32) = 1.9.20-1.fc25, but none of the providers can be installed
(try to add '--allowerasing' to command line to replace conflicting packages)



when i use --allowerasing :
dnf downgrade gnutls from Version:3.5.5 to 3.5.4-1.fc25 .

I'm not sure what is causing the problem, thank you anyway.
