Hi Troy, I got HTTP error 403 on http://ftp.scientificlinux.org/linux/scientific/55/x86_64/updates/security/repodata/repomd.xml, and it looks like the listing at http://ftp.scientificlinux.org/linux/ is empty. This mirror is referenced from our sl-security.repo configuration file, which, I believe, is just a stock SL5.5 one. Cheers, Jan
