Morning I have a yum bug. I built a cluster based on Fedora Core 2 and thought I might try to use yum to manage my cluster image. I have a 4GB file system image which I install across all my cluster nodes. This image is mounted on the server via a loop back device. I am trying to use yum from the server to manage the cluster image. It crashes... oh, to complicate things further, my server is x86 and the nodes are x86_64. [root@node0 ~]$ mount -o loop /opt/ftp/node.img /mnt/node [root@node0 ~]$ yum --installroot=/mnt/node check-update Unable to find pid Gathering header information file(s) from server(s) Server: Fedora Core 2 - i386 - Base Server: Fedora Core 2 - i386 - Released Updates Finding updated packages Traceback (most recent call last): File "/usr/bin/yum", line 30, in ? yummain.main(sys.argv[1:]) File "/usr/share/yum/yummain.py", line 249, in main (uplist, newlist, nulist) = clientStuff.getupdatedhdrlist(HeaderInfo, rpmDBInfo) File "/usr/share/yum/clientStuff.py", line 447, in getupdatedhdrlist rpmarchs = bestversion(rpmnevral, name) File "/usr/share/yum/clientStuff.py", line 495, in bestversion currentarch = archs[0] IndexError: list index out of range [root@node0 ~]$ Hope this helps Stu. -- <---------------------------------------------------------------------> Dr Stuart Midgley | stuart.midgley@xxxxxxxxxx Supercomputer Facility | smidgley@xxxxxxxxxxxxxxx Leonard Huxley Building 56 | +61 (0)2 6125 5988 Work Australian National University | +61 (0)2 6125 8199 Fax CANBERRA ACT 0200 | +61 (0)4 1125 2488 Mob
