Fabio Bettoni ran into a problem when trying to update to the new glibc on CowboyHat F10. I made a big mistake when I built this. I built it in the F11 environment that uses a new version of rpm. The new version of rpm changes how it does checksums in the packages. The older version doesn't read these properly. I have uploaded a new version of rpm to the updates directory. Please do the following to prevent trashing your install: yum clean all yum update rpm rpm -q rpm (ensure you are now running version 4.6.0-11 or newer) yum update (to grab any other updates pending such as glibc) I applogize for this mistake, I was lazy and just grabbed the F11 glibc without even thinking that it would not install with the old rpm. Glad to hear someone else has tried installing this however :) It appears that many others are downloading this right now based on how slow my download speed is. I normally see about 500k and am seeing about 30k right now. We may need to see if anybody can mirror this to support the load. Dave
