I was upgrading a system from F28 ro F29 and the power failed during the upgrade. I don't know what point the upgrade was at when it failed. The basic problem is that most (but not all) dnf commands just die with a traceback:
[root@elric greg]# dnf clean all
Failed to set locale, defaulting to C
34 files removed
[root@elric greg]# dnf check-update
Failed to set locale, defaulting to C

When I first brought it back up, there were a lot of dups (f28 and f29 packages both installed). I painstakingly (using rpm) removed all the dups, so that now "dnf check" runs with no output (other than the locale complaint). But commands like "update", "check-update", "install" will just get the traceback. The system seems to be running OK (although still with an F28 kernel), but of course it is now impossible to update it.
Is there a way to fix this? I'm thinking I could have had a working system by now by just installing F29 from scratch, but I'm also trying to learn here. Is a full install my only option at this point?
Thanks,
--Greg
