Description of problem: After upgrading to F26 I have some problems with duplicated rpm packages: $ rpm -q dnf dnf-2.5.0-1.fc26.noarch dnf-2.5.0-2.fc26.noarch So I wanted to run distro-sync, but I run into more problems. Version-Release number of selected component (if applicable): see above How reproducible: on my machine :( Steps to Reproduce: LANG=C.utf8 sudo dnf distro-sync Actual results: Error: Problem: The operation would result in removing the following protected packages: dnf Segmentation fault Expected results: No segmentation fault. Let me know how to help and what to investigate.
