[Yum] [Errno -3] Error performing checksum

[Steven McKinney]

Hello,

I have yum version 3.0.6 on a linux box running CentOS 6, and can not get yum to do any installs or updates.

I keep getting a "[Errno -3] Error performing checksum" error as shown below.

Hints on the web point to incompatible checksum programs, and machines updated from CentOS 5 to 6.  

At this point yum is wedged, no updating or installing seems possible.

Has anyone dealt with this issue?  How can I patch yum without yum?

Any info appreciated.
