When attempting to upgrade from Fedora Core 27 to Fedora Core 28, it may fail on the nss-pem package.

 

I spent some time trying to find the solution for this, and came across numerous posts on the “Red Hat Bugzilla”, particularly this post.

See below example:

[root@SYSTEMZ01 ~]# dnf system-upgrade download --releasever=28
Before you continue ensure that your system is fully upgraded by running "dnf --refresh upgrade". Do you want to continue [y/N]: y

Error:
 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

To resolve this, manually install the nss-pem packages from FC28 prior to the upgrade using the following command.

dnf install nss-pem-1.0.3-9.fc28 --releasever=28

After doing so, re-attempt to upgrade and the upgrade should now proceed.
