Resolution

You can restrict yum to install or upgrade a package to a fixed specific version and not to a later version than specified using the versionlock plugin of yum.

To do this, follow:

1. Install package named yum-plugin-versionlock (called yum-versionlock in RHEL 5).

   # yum install yum-plugin-versionlock
   

   The /etc/yum/pluginconf.d/versionlock.list will be created on the system.

2. To install or lock the version of the gcc package, add that package name to the /etc/yum/pluginconf.d/versionlock.list file by running:

   # yum versionlock gcc-*
   

   (Alternatively, you can edit the filelist, /etc/yum/pluginconf.d/versionlock.list, directly.)

• The above configuration will not allow to upgrade the gcc package to version greater than what was installed at the time the locking was performed.
• Yum will attempt to update all packages, while excluding the packages listed in the versionlock file.

Other Commands

To display the list, use:

# yum versionlock list

To discards the list, use:

# yum versionlock clear
