Apache failed to update and will not start - immutable files

Symptoms

Apache packages failed to update properly and there is an error similar to:

error: unpacking of archive failed on file /path/to/a/file: cpio: rename

Description 

When yum attempts to update packages but encounters files that are made immutable through the use of the 'chattr +i' command, an error similar to the above can be seen. This can cause various issues with the service as a whole such as preventing it from starting correctly.

Workaround

Check the attributes of the file listed in the error with:

lsattr /path/to/a/file

Example:

lsattr /usr/lib/udev/rules.d/60-net.rules
----i----------- /usr/lib/udev/rules.d/60-net.rules

The 'i' denotes that it is immutable, remove this attribute with:

chattr -i /usr/lib/udev/rules.d/60-net.rules
