Warning: user mockbuild does not exist: using root
May 10, 2010 | Posted byThe ‘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:
# yum install mock
and create the ‘mockbuild’ user
# useradd -s /sbin/nologin mockbuild
Once done, you should be able to install the required tool under the mockbuild user.
