I upgraded my system before upgrading to 27 and I run the following command.

sudo dnf system-upgrade download --refresh --releasever=27

but this command gave me this error:

 Problem: nss-pem-1.0.3-3.fc26.i686 has inferior architecture
  - nss-pem-1.0.3-3.fc26.x86_64 does not belong to a distupgrade repository
  - problem with installed package nss-pem-1.0.3-3.fc26.i686

I tried to do this using software center but software center gave me unable to upgrade error message too.

how can I fix this problem and update to my system to 27 ? thanks.

First try dnf upgrade. Then you can try to get rid of i386 and i686 packages in your system. Provided nss-pem is the problem, try installing x86_64 nss-pem (and if possible removing the i386 version). Then try downloading again.

Also might be worth reporting bug in

Another possible issue might be that the x86_64 version of nss-pem was not yet pushed to the repo while you saw newer version in i386. So perhaps if you just try again later or against different mirrors it would work.
