Hi everyone, I'm following these instructions: http://www.brandonhutchinson.com/Upgrading_Red_Hat_Linux_with_yum.html and have got as far as the step where you start the upgrade process. However, I've hit this problem: [root@az bin]# yum upgrade Traceback (most recent call last): File "/usr/bin/yum", line 6, in ? import yummain File "/usr/share/yum-cli/yummain.py", line 23, in ? import yum ImportError: No module named yum Any ideas? Thanks, James. -- No virus found in this outgoing message. Checked by AVG Anti-Virus. Version: 7.0.300 / Virus Database: 265.8.8 - Release Date: 14/02/2005
