After playing with conda and possibly reconfiguring python3, I find that dnf no longer works.

$ dnf
Traceback (most recent call last):
  File "/usr/bin/dnf", line 57, in <module>
    from dnf.cli import main
ModuleNotFoundError: No module named 'dnf'

I have tried using yum and rpm to reinstall dnf. They seem to point back to dnf. I have tried using the gnome software package to delete and install dnfdragora. I see no reference to dnf or dnf-core.

Have I exhausted the easy options?

My next step is to try rebuilding dnf from the github source but the first step

sudo dnf builddep dnf.spec

doesn't look promising, but I will try it anyway. Maybe I can reroute the installation from a LiveCD?

I made some progress but no luck yet, from


I found I can reach the repositories at

and I was able to find and download the four rpm packages


and I am able to run rpm (unlike what I said above)

sudo rpm --reinstall dnf*

sudo rpm --reinstall dnf*

but I got warnings like /sbin/ldconfig: libraries and in directory /lib have same soname but different type.

(I may not be completely upto date.)

but running dnf still gives the error:

No module named 'dnf'

I'm beginning to think I have to reinstall Fedora.

as stated above I reinstalled dnf. I downloaded the python3 rpm, and a few of the python3-dnf rpms. but before I could install them with rpm, I ran into other problems. I think Gnome went unstable. I could not enter a password to unfreeze the screen. It looked like only one character was processed at a time. Then, after using power button to shut down, the system stopped booting - so I did a reinstall anyway

I think I will create a dedicated conda user and not install anaconda with sudo. Conda and dnf do not play well together.

Have a look at this

To avoid this there will be atomic updates

Me too had a broken Fedora 28 due to iresponsive update but I reinstalled completely. The chance to have an inconsistent system is too big.

Good luck.
