When I attempted to upgrade from Fedora 25 to Fedora 26 I received the following errors:
Error: Transaction check error:
file /usr/share/applications/org.gnome.gedit.desktop conflicts between attempted installs of gedit-2:3.22.1-1.fc26.i686 and gedit-2:3.22.1-1.fc26.x86_64
Using the upgrade command:
dnf system-upgrade download --allowerasing --refresh --releasever=26
Thanks for any suggestions on this problem..
