yum-arch dies when it tries to read a file that is not actually a rpm. This happend to me running yum-arch on a mirror of rh71 (yes, I know it's old) where some rpms are in fact missing, and you find instead a sort of acces denied message from the master server "masqueraded" as rpm: [root@ring updates]# yum-arch -z `pwd`/7.1 <many lines/> Digesting rpms 84 % complete: php-imap-4.0.6-9.7.1.i386.rpmTraceback (innermost last): File "/usr/sbin/yum-arch", line 23, in ? pullheaders.main() File "pullheaders.py", line 221, in main File "pullheaders.py", line 55, in genhdrs TypeError: unsubscriptable object [root@ring updates]# file 7.1/sec/php-imap-4.0.6-9.7.1.i386.rpm 7.1/sec/php-imap-4.0.6-9.7.1.i386.rpm: HTML document text [root@ring updates]# cat 7.1/sec/php-imap-4.0.6-9.7.1.i386.rpm <TITLE>FTP Error</TITLE> <H1>FTP Error</H1> <h2>Could not login to FTP server</h2> <PRE>Anonymous User Limit Reached, See http://www.redhat.com/mirrors.html</PRE> Piero
