Description of problem:
$ rpm -q nss-pem
Version-Release number of selected component (if applicable):
I get error like this,
Problem: nss-pem-1.0.3-6.fc27.i686 has inferior architecture
- nss-pem-1.0.3-6.fc27.x86_64 does not belong to a distupgrade repository
- problem with installed package nss-pem-1.0.3-6.fc27.i686
$ dnf repoquery --releasever 28 nss-pem
Seems like i686 package is missing.
Same problem was there for f26,
There's a workaround in bug 1553646.
