I just messed up and did: # dnf --enablerepo=updates-testing upgrade and upgraded everything instead of just the thing I was trying to upgrade. I want to undo that, but it seems to be impossible. # dnf history undo 119 [...] No package libreoffice-base-1:4.3.5.2-11.fc21.x86_64 available. Error: An operation cannot be undone # dnf distro-sync Using metadata from Tue Feb 24 17:15:49 2015 Error: package ghostscript-x11-9.15-6.fc21.x86_64 requires ghostscript(x86-64) = 9.15-6.fc21, but none of the providers can be installed Gee, thanks. As it happens, # dnf distro-sync --allowerasing works. Perhaps # dnf distro-sync could suggest --allow-erasing. Also, there's a bug here: # dnf distro-sync --allowerasing [...] Transaction Summary ================================================================================ Downgrade 132 Packages Total download size: 186 M Is this ok [y/N]: y So I shouldn't have needed --allowerasing in the first place. An alternative would be to add a most that undoes the last transaction and updates at the same time. That way it could undo my accidental transaction but only depend on versions of packages that still exist in updates. --Andy -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct
