I just started working with Oracle’s VirtualBox VM for WebCenter. Much easier for development – everything (all 6 apps!) are already installed. But I ran into a problem updating it. I received the following message:
[Errno 256] No more mirrors to try
Unfortunately, the one query I found about it on the Oracle mailing lists only said that the message referred to the fact that the user was trying to reach a link inside of Oracle when he was neither an employee or a contractor. And there wasn’t an answer listed to how to fix the issue.
The discussion was closed. Hopefully, someone will find this post if they ever run across the same situation.
The error is due to the fact that yum is set up to try to go through an Oracle proxy to get to the yum servers. To fix the error, open /etc/yum.conf and either remove or comment out the line with the proxy. After that, it works just fine.
