Sorry, but not everybody is on production machines.
Since the OP could not analyze himself the error message, one could safely assume he is not dealing with critical production environments. Maybe he was just told: "install quickly this CentOS in VirtualBox, just to make sure our app is compatible", and in that case the sooner the better.
My "advice" and those of others where underlying the security risk. The one of Akemi seems pretty safe (not installing the update).
To put it shortly: Freedom, as in "free software", is about doing whatever you want.
Not updating is entirely sensible and sounds like the best default position. Installing a package you'd expect to be signed when it isn't signed should ring alarm bells.
Freedom includes being free to make poor decisions.
