(ok, let's see if i can make a mess of this as well.) after uncommenting my yum.conf entries for the FC 1 development repos, i get the following after running "yum update": Finding updated packages Downloading needed headers retrygrab() failed for: http://distro.ibiblio.org/pub/linux/distributions/fedora/linux/core/ development/i386/headers/XFree86-ISO8859-14-100dpi-fonts-0-4.3.0-64.i386.hdr Executing failover method retrygrab() failed for: http://www.muug.mb.ca/mirror/redhat/fedora/linux/core/development/i386/ headers/XFree86-ISO8859-14-100dpi-fonts-0-4.3.0-64.i386.hdr Executing failover method retrygrab() failed for: http://ftp.dulug.duke.edu/pub/fedora/linux/core/development/i386/headers/ XFree86-ISO8859-14-100dpi-fonts-0-4.3.0-64.i386.hdr Executing failover method retrygrab() failed for: http://mirrors.kernel.org/fedora/core/development/i386/headers/ XFree86-ISO8859-14-100dpi-fonts-0-4.3.0-64.i386.hdr Executing failover method failover: out of servers to try Error getting file http://distro.ibiblio.org/pub/linux/distributions/fedora/linux/core/development/i386/headers/XFree86-ISO8859-14-100dpi-fonts-0-4.3.0-64.i386.hdr [Errno 4] IOError: HTTP Error 404: Not Found i checked the first of these repos and, while the header.info file has an entry for that RPM (that XFree fonts RPM), there is no such header file. in fact, the header.info file lists several font RPMs, none of which exist in that directory. does that mean the repo is somehow damaged or incomplete? what is the meaning of entries in header.info that don't actually exist in the directory? and notice that i get the same error for *all* of my listed development repos. not surprising, if they mirror from a common source, they'll have common errors. or am i misinterpreting this message? rday p.s. none of the other repos i have listed in my yum.conf file show this diagnostic.
