After upgrading from Fedora 10 to 11 using the following instructions, I encountered the errors detailed below.
http://www.cyberciti.biz/faq/upgrade-fedora-11/
Upon boot, immediately encountered the following error.
Traceback (most recent call last):
File "/usr/sbin/yum-updatesd" . line 41. in <module>
from yum.config import BaseConfig. Option, IntOption, ListOption, BoolOption
ImportError: No module name yum.config |
Upon trying to run #yum update , I encountered the following error.
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:
No module named yum
Please install a package which provides this module, or
verify that the module is installed correctly.
It's possible that the above module doesn't match the
current version of Python, which is:
2.6 (r26:66714, Mar 17 2009, 11:44:21)
[GCC 4.4.0 20090313 (Red Hat 4.4.0-0.26)]
If you cannot solve this problem yourself, please go to
the yum faq at:

The following rpm -qa output reveals that the Fedora upgrade left remnants of the yum for Fedora 10. By downloading the Fedora 11 yum rpm's and installing them, the problem was resolved.
# rpm -qa | grep yum
yum-utils-1.1.22-1.fc10.noarch
yum-3.2.23-3.fc10.noarch ---- Below command, where you prefix each rpm file with the location of the repository where you're downloading them from.
# wget yum-3.2.23-3.fc11.noarch.rpm yum-utils-1.1.22-1.fc11.noarch.rpm
Then, install the downloaded rpm's. # rpm -Uvh yum*.rpm Preparing... ########################################### [100%]
1:yum ########################################### [ 50%]
2:yum-utils ########################################### [100%] |
But alas, there was one more error encountered with yum when running a #yum update.
ERROR : File /var/cache/yum/updates/metalink.xml does not exist
Had to do a #yum clean all
which fixed that error message.
