Issue

To ensure that upgrades and installations proceed smoothly, it is necessary to remove any proxy settings beforehand. This is because the process relies on receiving accurate responses to multiple API calls, which can misfire if a proxy is set up. After the upgrade or installation is complete, custom proxy settings can be re-added.

Resolution

Navigate to ‘/etc/yum.conf’ file and remove the proxy information. Follow these steps to remove the proxy information:

1. vi /etc/yum.conf Get into insert mode (press i)

2. Remove the following lines:

proxy= <porxy_URL>
proxy_username=<proxy_username>
proxy_password=<proxy_password>

3. Save the changes.
