It should be ftp://ftp.scientificlinux.org/linux/scientific/44/i386/SL/RPMS/repodata/repomd.xml and not ftp://ftp.scientificlinux.org/linux/scientific/44/SL/RPMS/repodata/repomd.xml It looks like your arch (i386 or x86_64) was not detected at all ??? Can you please post your /etc/yum.repos.d/sl.repo file? and your yum version: rpm -q yum Normally in /etc/yum.repos.d/sl.repo there is a line baseurl=ftp://ftp.scientificlinux.org/linux/scientific/44/$basearch/SL/RPMS/ yum should set $basearch=i386 ending up with ftp://ftp.scientificlinux.org/linux/scientific/44/i386/SL/RPMS/repodata/repomd.xml and not with ftp://ftp.scientificlinux.org/linux/scientific/44/SL/RPMS/repodata/repomd.xml Other people have seen the same problem, unfortunately I don't have a SL44 system.
