Hi I just installed yum-1.0-20030508.noarch.rpm on my RH8.0 machine and I get the following error when I run yum arch. [root@hannah up2date]# yum arch Traceback (most recent call last): File "/usr/bin/yum", line 22, in ? import yummain ImportError: Bad magic number in /usr/share/yum/yummain.pyc and I get the same error when I try yum update [root@hannah i386]# yum update Traceback (most recent call last): File "/usr/bin/yum", line 22, in ? import yummain ImportError: Bad magic number in /usr/share/yum/yummain.pyc yum arch and yum update used to run fine using yum-1.0-1_80.noarch.rpm Looks like back to 1.0-1 for me. Can we post bugs here? Thanks PS. YUM is sweeeeet -- Open WebMail Project (http://openwebmail.org)
