Hello,

Sorry ahead of time if I have missed any other thread or blog on this issue. We are running AIX 7.3 TL2 SP2 and have DNF with a local repo configured and it was working before upgrading to TL2 SP2. I found the thread -> AIX Open Source Tip: DNF errors missing libnss3.so in 73 TL2. We weren't aware of the conversion from db to sqlite and the upgrade of DNF wasn't performed prior to updating to TL2/SP2.

Which is exactly the same error I am receiving either on existing AIX servers that have DNF already installed or new AIX servers that I am trying to install DNF on. I am using this link to go through the install process on a new server -> https://community.ibm.com/community/user/blogs/sangamesh-mallayya1/2022/02/09/creating-local-repo-with-dnf-and-aix-toolbox-media?CommunityKey=10c1d831-47ee-4d92-a138-b03f7896f7c9. Below is the process and outcome on a new install. If someone could please direct me to documentation on how to resolve this for new servers installing DNF or exist ones that already have it installed. I would think it'd be the same solution.

New install:
