  • 1.  Not able to run DNF update command after AIX 7.2 to 7.3

    Hi Team,

    We are getting following errors after OS upgrade from 7.2 to 7.3. Do we any solution for this?

  • 2.  RE: Not able to run DNF update command after AIX 7.2 to 7.3

    Posted Tue June 10, 2025 07:50 AM

    I have run into several problems after using/updating YUM and DNF on AIX 7.3 after upgrading from 7.2.

    So far I have come a few steps that helped me out, so I now always follow these steps:

    1. Download the "dnf_aixtoolbox.sh" script 
      from https://public.dhe.ibm.com/aix/freeSoftware/aixtoolbox/ezinstall/ppc/dnf_aixtoolbox.sh
    2. Run the script, probably with "-y" argument if you want to keep YUM available also:
              ./dnf_aixtoolbox.sh -y
    3. Check to see if /opt/freeware/bin is in the search path ($PATH) for root.
      If it isn't, added it to the end:
              export PATH=$PATH:/opt/freeware/bin
      If is is, try to place it at the front, quick & dirty:
              export PATH=/opt/freeware/bin:$PATH  

    I recommend making mksysb backup before you try this.
