Insufficient information.

Publishing the error messages was a good idea, but what you you mean by "upgrade"?

Are you trying to upgrade from Windows 2000 to Red Hat 9.0?

Are you trying to upgrade from Slackware 4.0 to SUSE 7.0?

When does this error occur? When you insert the CD? When you load a specific package? After the third screen of the Red Hat 6.1 installation? Whenever you get mail advertising viagra?

Somebody might be able to help if we all knew what you are trying to do.

"upgrade" means i have installed redhat linux 9.0 but some rpms is wrong ,so i want to reinstall it.
