Hello Bryan,
(a) in the main menu, select System Settings | Add/Remove AppolicationsI've installed Fedora Core 1 yesterday, and got exactly the same error when trying to install packages. I some cases, even, the redhat-config-packages hanged forever and I had to kill it manually.
(b) the system checks what I have and gives me a list of things to tick and untick, etc. No problem.
(c) I tick xpdf to install that - nothing else.
(d) I click Update and the system tells me how many packages are queued for installation. Up to now, no problem.
(e) I click continue and the system gives me a message saying disk 2 is needed.
(f) I put in disk 2, click OK and get an error message and it closes.
I've tried to install a few RPMs directly from the FC1 CDs, and it worked for a few RPMs. After that, the package manager stalled. I had to kill it manually.
The only way I've found to install the RPMs from the FC1 CDs is to check the "All packages" box when installing FC1.
I've also tried to use the up2date tool, but found that the GPG Key for the glibc-common.xxx.rpm was corrupted (sic!) and did not dare to install it further.
Has anyone else found out what was wrong with the FC1 Package Manager?
I've noticed, though, that there is an updated version of that Package Manager in the test updates (http://download.fedora.redhat.com/pub/fedora/linux/core/updates/testing/1/i386/redhat-config-packages-1.2.7-1.noarch.rpm), but I've not tried to install it.
