Hi SL Team, it seems the metadata for SL6.7 has some issues. On my 6.7 systems yum complains ... 6.7/x86_64/updates/security/repodata/primary.sqlite.bz2: [Errno -1] Metadata file does not match checksum I've already done a re-sync and a 'yum clean all', could you please verify the 6.7 metadata? ls -ltr /mirror/linux/scientific/6.7/x86_64/updates/security/repodata/ total 8509 -rw-r--r-- 1 root wheel 1181784 Apr 26 23:51 primary.xml.gz -rw-r--r-- 1 root wheel 69860 Apr 26 23:51 other.xml.gz -rw-r--r-- 1 root wheel 1973074 Apr 26 23:51 filelists.xml.gz -rw-r--r-- 1 root wheel 2391386 Apr 26 23:51 primary.sqlite.bz2 -rw-r--r-- 1 root wheel 127155 Apr 26 23:51 other.sqlite.bz2 -rw-r--r-- 1 root wheel 1868170 Apr 26 23:51 filelists.sqlite.bz2 -rw-r--r-- 1 root wheel 67539 Apr 27 00:11 updateinfo.xml.bz2 -rw-r--r-- 1 root wheel 499777 Apr 27 00:11 updateinfo.xml -rw-r--r-- 2 root wheel 2969 Apr 27 00:14 repomd.xml -- Thanks, olli
