Error unable to run dnf localinstall *.rpm

I am trying to install Nginx on my rhel 8.7. I am not able to run dnf localinstall *.rpm on a non-internet environment and it is showing some errors.

I tried check the /etc/yum.repos.d directory but not sure what to do. Please advise.

>Solution :

I suggest you to check your /etc/yum.repos.d and check if there are any repo files in the directory. If there are, try to edit the repo files and change the gpgcheck=0 and type in the terminal:

1. yum repolist
2. yum list
3. Try to run dnf localinstall *.rpm again.

It should work now.
