I am currently running Magento version 1.8.1, I am looking to upgrade it. When I went to go start the upgrade process I got the following error: "channel-add: Cannot connect to host: connect20.magentocommerce.com" so, I am not sure how to resolve this since I am very new to Magento. Can someone provide me some idea on what to do?
./mage mage-setup .
Running initial setup...
