Please throw me a bone on how to fix this!

try dnf clean all

Check networking, check name resolving.

Thank you. it could be our firewall.
using dhcp dnf install works

To change an ip of a headless server I run:
#!/bin/bash
nmcli con mod enp0s3 ipv4.addresses 192.168.1.13/24;
nmcli con mod enp0s3 ipv4.gateway 192.168.1.1;
nmcli con mod enp0s3 ipv4.method manual;
nmcli con mod enp0s3 ipv4.dns "8.8.8.8";
nmcli con up enp0s3;
ip addr show enp0s3;

We then manually edit:
/etc/resolve.conf

Then we the dnf error.
I will not be able to work on this for about 5 days.

Now we are getting this error on the initial install:

Failed to synchronize cache for repo 'extras', ignoring this repo.

Andy ideas?
