warning: user mockbuild does not exist - using root

I am trying to install below rpm but enable to install facing issue.

when i am trying to run a rpm file... i am getting this error massage..

[root@chintels Desktop]# rpm -ivh --force firefox-3.6.11-2.el5.src.rpm

warning: firefox-3.6.11-2.el5.src.rpm: Header V3 DSA signature: NOKEY, key ID 37017186
 
1:firefox                warning: user mockbuild does not exist - using root

warning: group mockbuild does not exist - using root

warning: user mockbuild does not exist - using root

Solution:-

The ‘mock’ module is responsible to build the source RPMs (SRPMs) under a chroot environment
and uses the ‘mockbuild’ user.
If the mockbuild user does not exist while installing the source RPM,
you will receive the ‘Warning: user mockbuild does not exist. using root‘ error message.


In order to fix the warning message, install the ‘mock’ module:

[root@sujeet ~]# useradd -s /sbin/nologin mockbuild
[root@sujeet ~]# cd Desktop/

Once done, you should be able to install the required tool under the mockbuild user.

[root@sujeet Desktop]# rpm -ivh firefox-3.6.11-2.el5.src.rpm
