Can someone please help me on this.

Please provide the output of "head /opt/freeware/bin/dnf-3" and "rpm -qf /opt/freeware/bin/dnf".

Hi Sangamesh,

Thank you for helping .. I found this and fixed the problem..

when i checked yum command which is point to dnf-3  is working as expected.. So i viewed the dnf and dnf-3 files under 
/opt/freeware/bin
lrwxrwxrwx    1 root     system            5 Jan 26 17:48 yum -> dnf-3

dnf-3 shows 

#!/opt/freeware/libexec/python3.12_32
# The dnf executable script.

dnf shows :

#!/opt/freeware/bin/python3.12
# The dnf executable script.

I modified dnf script and point to the same 

after update:

#!/opt/freeware/libexec/python3.12_32
# The dnf executable script.

dnf start working as expected ..

Hopefully some bug in dnf script and it will be update in new releases.
