Hello team,

It would seem this is an ongoing issue with dnf and post 7.3 installation. I am also having something similar and I have tried a couple of different ways to correct the issue to resolve the problem.

This came to my attention far to late after a 7.3 migration and rolling back to 7.2 at this time is not really an option. I do have the old version to test with if needed, but reverting back would cause tons of rework just to get dnf working again.

So to start this is the error I get:

>dnf
Traceback (most recent call last):

        0509-022 Cannot load module librpm.so.
        0509-026 System error: A file or directory in the path name does not exist.

This issue led me to other forum post and guides by samgamesh:

AIX migration with DNF

However, this has led me to believe that I needed to purge old RPMs/dnf and start fresh. I was able to uninstall all rpms on the lpar and tried again with dnf_install. The result can be seen below. I have a backup copy that I can jump back and forth between while testing this setup.

Any assistance or insight is greatly appreciated.

Hi Ken,

Please run "udtvpkg" and then retry. 

We would also like to know what error caused you to decide to purge installed packages and then setup DNF freshly.
