Hello, we removed everything related to rpm and dnf then ran the following commands to do the install for AIX 7.3 - 

./destroyRPMS

/usr/sbin/updtvpkg

./install_dnf.sh -d

dnf installed successfully.
Please run 'dnf update' to update packages to the latest level.

Please note, RPM packages are downloaded in dnf cache /var/cache/dnf.
RPM packages install files go under the path /opt.
Hence it is recommended to always keep at least 512MB of free space in /var & /opt
to avoid any download and installation/update failures.

Then did this - and this is where it's failing:

You should unlink/remove this file :

/opt/freeware/lib/libssl.a

That does not look like an AIX openssl.base library.

The following should have printed out at the end of the destroyRPMs script

 Your rpms have been removed, but the /opt/freeware and /usr/opt/freeware directories (one is just a symbolic link) have been left present.  You may want to look through these directories for any files you may have created yourself.  If there is nothing that you want to save, you can now remove these directories and any remaining contents within.
