AIX Open Source Tip: DNF librpm.so.9 errors after migration to AIX 73

Question & Answer


Question

I migrated to AIX 73, and now DNF will not run.

# dnf list installed

Answer

The /opt/freeware/lib/libdnf.a is a 32-bit library.
DNF uses the rpm binary to manage RPM packages. In AIX 7.1 and 7.2, the default rpm is 32-bit.
The default rpm is 64-bit in AIX 7.3. Therefore, DNF must be updated to 64-bit.
As noted on the AIX Toolbox "What's New" page:
  • DNF steps are required for migration to AIX 7.3.
    • When DNF users migrate from 32 bit AIX 7.1 or 7.2 to 64 bit AIX 7.3 then the existing installed DNF won’t work as-is. Some additional steps are required.
    • See AIX migration with DNF for recommended steps.
NOTE for YUM users: It is recommended to migrate to DNF before migrating to AIX 7.3.
