I got a warning message while installing Webmin/Virtualmin, similar to this thread: https://www.virtualmin.com/node/22850
My server is running CentOS 6.4 32bit, and all I typed was "sh ./install.sh" according to this page: http://virtualmin.com/documentation/installation/automated
Most websites (including this one: http://www.ehowstuff.com/how-to-fix-warning-rpmdb-altered-outside-of-yum/) say you should either type "yum clean all" or "yum history new" to fix it (both of which I did try but they didn't seem to do much of anything, or if they did I still have no idea if they fixed the problem).
But also at the end of the installation itself, it does say "INFO - yum clean all" (just like in the thread mentioned above: https://www.virtualmin.com/node/22850), so did it fix the problem itself? Or do I need to try something else?
I have on occasion seen that... I'm not sure what causes that warning, but I've never actually seen it cause any problems.
That is, if the installation completes successfully, and you aren't continuing to see any yum errors/warnings, you should be okay..
That's good enough for me. Thanks for the quick reply!
