  • 1.  dnf is broken after installing TL2 on AIX 7.3 hosts

    Posted Tue May 28, 2024 02:13 PM

    All hosts that have been upgraded from 7.3 TL1 to 7.3 TL2 fail with the following error:

    Libpath isn't set, but that hasn't been an issue until now.

    Hi Erik

    Your dnf ecosystem is still based on python3.7. 

    We always recommend users to update packages to latest version from AIX Toolbox to avoid any errors.

    We wrote a detailed post on python3.9 migration https://community.ibm.com/community/user/power/discussion/migrating-to-python39-for-aix-toolbox-python3-ecosystem#bm7c12cb47-fe61-441f-924e-0188afd09151

    Now to resolve your current issue and make dnf work run the below steps.

    1. rpm -e libcomps python3-libcomps dnf dnf-automatic dnf-data python3-dnf libdnf python3-libdnf python3-hawkey librepo python3-librepo
    2. run dnf_aixtoolbox.sh
    3. run "dnf update"
