I get the same error with SL-60-x86_64-2011-03-03-Everything-DVD1. I verified the checksum, verified the DVD when I burned it, tested it dur ing the install - no errors.
"Error Installing Package: A fatal error occurred when installing the dbus package. This could indicate errors when reading the installation media. Installation cannot continue." I read about the same problem with a Fedora installation, so I tried it again without adding any repos, and less customization. Then I got the same message with "dbus" replaced by "polkit-desktop-polic y". So I tried using an external DVD drive via USB - same problem. So, I tried the install DVD SL-60-x86_64-2011-03-03-Install-DVD - I still choke on "polkit-desktop-policy". By now I am doing just a "Desktop" inst all with virtually no customization. So I tried it on a completely different system - same problem. I may have the sequence a little mixed up, but at the end of a long Frida y night, I was getting the error on "polkit-desktop-policy" from Install-DV D. I get this in install.log : Installing polkit-desktop-policy-0.96-2.el6.noarch warning: polkit-desktop-policy-0.96-2.el6.noarch: Header V4 DSA/SHA1 Signature, key ID 192a7d7d: NOKEY error: %pre(polkit-desktop-policy-0.96-2.el6.noarch) scriptlet failed, ex it status 127 Monday I tried the boot CD, SL-60-x86_64-2011-03-03-boot, and did a netwo rk install from ftp1.scientificlinux.org/linux/scientific/6.0/x86_64/os/ - i t finished within 2 hours without a problem. Maybe I will try the Live DVD next time. I have installed SL 5.x maybe dozens of time over the past few years and I hope to install SL 6.x many more times - I love it for use in DVT of new hardware. If there is any way I can make this easier, I would appreciate it if I could learn how.
