This article is being updated. Please be aware the content herein, not limited to version numbers and slight syntax changes, may not match the output from the most recent versions of Bright. This notation will be removed when the content has been updated.

The manual does discourage using the add-on methodIf the prerequisites listed in the manual are not met, then that may be the reason. So, read that section of the manual carefully first.

If that doesn’t help, the following run-through of the add-on method on a centOS 6.5 virtual machine illustrates the installation process so that you can compare matters to see if anything unexpected shows up. At the end of the procedure, some troubleshooting issues that may come up are dealt with.
