How to resolve problems installing netplan rpm

I am attempting to install netplan on Rocky 9.3 which has no direct internet connection. So I am trying to install packages via rpm and if see a failed dependency find it and scp it to the PC (Intel PC running Rocky 9.3).

[user@localhost ~]$ rpm -i netplan-0.105-3.el9.x86_64.rpm 
warning: netplan-0.105-3.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3228467c: NOKEY
error: Failed dependencies:
	netplan-default-backend is needed by netplan-0.105-3.el9.x86_64
	netplan-libs(x86-64) = 0.105-3.el9 is needed by netplan-0.105-3.el9.x86_64

So I then try to install netplan-libs:

[user@localhost ~]$ sudo rpm -i netplan-libs-0.105-3.el9.x86_64.rpm
warning: netplan-libs-0.105-3.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3228467c: NOKEY
	package netplan-libs-0.105-4.el8.x86_64 (which is newer than netplan-libs-0.105-3.el9.x86_64) is already installed
        file /usr/lib64/libnetplan.so.0.0 from install of netplan-libs-0.105-3.el9.x86_64 conflicts with file from package netplan-libs-0.105-4.el8.x86_64

Then I try to remove what I thought was the wrong netplan-libs as in:

[user@localhost ~]$ sudo rpm -e netplan-libs-0.105-4.el8.x86_64.rpm 
error: package netplan-libs-0.105-4.el8.x86_64.rpm is not installed

Then I try to verify netplan:

[user@localhost ~]$ sudo rpm -V netplan-0.105-3.el9.x86_64.rpm 
[sudo] password for user: 
warning: netplan-0.105-3.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3228467c: NOKEY

How do I reliably install netplan. I have downloaded what seem to be all the dependent files:

ls -l
-rwxr--r--. 1 user user  123581 Jun 24 14:39 netplan-0.105-3.el9.x86_64.rpm
-rwxr--r--. 1 user user    8221 Jun 24 15:21 netplan-default-backend-networkd-0.105-3.el9.noarch.rpm
-rwxr--r--. 1 user user    8273 Jun 24 15:35 netplan-default-backend-NetworkManager-0.105-3.el9.noarch.rpm
-rwxr--r--. 1 user user    8636 Jun 24 15:10 netplan-default-backend-NetworkManager-0.105-4.el8.noarch.rpm
-rwxr--r--. 1 user user  126265 Jun 24 15:40 netplan-libs-0.105-3.el9.x86_64.rpm
-rwxr--r--. 1 user user  123788 Jun 24 15:05 netplan-libs-0.105-4.el8.x86_64.rpm
-rwxr--r--. 1 user user   20996 Jun 24 15:13 NetworkManager-config-server-1.46.0-8.el9_4.noarch.rpm
-rwxr--r--. 1 user user   23050 Jun 24 15:15 python3-netifaces-0.10.6-15.el9.x86_64.rpm
-rwxr--r--. 1 user user  195078 Jun 24 15:18 python3-pyyaml-5.4.1-6.el9.x86_64.rpm

The most immediate problem I have is that I can't install netplan-libs-0.105-3.el9.x86_64.rpm because I get:

[user@localhost ~]$ sudo rpm -i netplan-libs-0.105-3.el9.x86_64.rpm 
[sudo] password for user: 
warning: netplan-libs-0.105-3.el9.x86_64.rpm: Header V4 RSA/SHA256 Signature, key ID 3228467c: NOKEY
	package netplan-libs-0.105-4.el8.x86_64 (which is newer than netplan-libs-0.105-3.el9.x86_64) is already installed
	file /usr/lib64/libnetplan.so.0.0 from install of netplan-libs-0.105-3.el9.x86_64 conflicts with file from package netplan-libs-0.105-4.el8.x86_64

So I try to remove netplan-libs-0.105-4.el8.x86_64 like this:

[user@localhost ~]$ sudo rpm -e netplan-libs-0.105-4.el8.x86_64.rpm 
error: package netplan-libs-0.105-4.el8.x86_64.rpm is not installed

Can I manually remove /usr/lib64/libnetplan.so.0.0 ? Or will that cause more problems? What is the best way to fix this?
