I have a machine where I tried to do a system-upgrade from F23 to F24. The download portion worked fine but after the reboot, the upgrade process aborted. I'd like to know why, but first I need to clean up the mess so I can try it again. Right now I have 4782 total packages installed including 1490 fc24 packages. I haven't checked all of them but it appears that all are paired with the same fc23 package. Trying to repeat the download step, I get this result. # dnf --allowerasing -y system-upgrade download --releasever 24 Last metadata expiration check: 0:23:15 ago on Tue Sep 6 15:53:47 2016. Dependencies resolved. Error: The operation would result in removing the following protected packages: systemd. Evidently, there are two systemd packages installed: # rpm -q systemd systemd-222-14.fc23.x86_64 systemd-229-13.fc24.x86_64 No new kernel was installed and the machine is running fine as F23. But I'd like to get it upgraded... I tried using "dnf history rollback" but that didn't work, reporting "A transaction cannot be undone". Since dnf won't erase the extra stuff, I can probably do it with something like, "rpm erase --force $(rpm -qa|grep fc24)" but that seems iffy. Better suggestions are very welcome. -- Dave Close -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://lists.fedoraproject.org/admin/lists/users@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
