If you do not have the Environment variable set for http_proxy, then
curl will not work. This seems like your problem to me.
To see if you have http_proxy set as an environment variable, use this
env | grep -i http_proxy
You need to check the above variable for both your "root user" and your
"local user" (local user's variables would be used if you are running
yum with sudo or su root ... root user would be used if you did "su -
root" or logged in directly as root.
If the result is in caps, like this:
Then curl might have an issue, so also add it in lower case like this:
So, If you do not have a lower case "http_proxy=", then you would set it
in your root's ".bash_profile" file and your local user's
".bash_profile" file. This is the line you would add to both users
After making the change, log out and back in to have the variables take
effect and then check them again with the grep command above ...
Once you have the correct lower case variable set for "http_proxy=" for
both your normal local user and for root, you should be able to use yum
