When i try to install the packages or software using the yum command, the following error or warning message appeared:
Warning: RPMDB altered outside of yum.
.. .. Running rpm_check_debug Running Transaction Test Transaction Test Succeeded Running Transaction Warning: RPMDB altered outside of yum. .. ..
This means some application has altered the rpm database (installed or removed a package) without going through the Yum APIs. To avoid this, it’s recommended to update, install or remove RPM packages using yum command, instead of ” rpm -e” or “rpm -i” or “rpm -ivh” or “rpm -Uvh”.
To fix this, just run this command :
[root@centos6 ~]# yum clean all Loaded plugins: fastestmirror Cleaning repos: CentOS6.2-Repository Cleaning up Everything Cleaning up list of fastest mirrors
