Which version of rpm are you using ? You can find that out by typing rpm --version

This is a known bug in rpm versions 4.3.0.x and has been fixed since version rpm-4.3.1-0.2 when built.

You can read about this at: https://bugzilla.redhat.com/show_bug.cgi?id=119783

If you're using the prior version, you should grab the newer one from RedHat archives. That'll solve your problem.

I know why it doesn't workIf the rpm installer can't establish a transaction lock, that is because installing rpm's has to happen under a ROOT account.so typesu<password>rpm -Uvh thingyouwanttoinstall.rpm
