Problems with Yum, Reporting Garbage Errors

[Ug]

I've been recieving the following error, whenever i try to use Yum. Yum has been working, but has now stopped.

I've attempted to reinstall yum but with no success. I'm behind a proxy, but yum was working until i had to logout whilst yum was still running. Since then i've had this problem. Any ideas?

[AndyGreen]

Does this help?

yum update yum

then try again

[Ug]

Not in the slightest. Peforming a:

su -
yum update

Results in:

Yum update yum, provides the same result.

[AndyGreen]

The code traceback seems to show an attempt to parse a broken or empty mirror list?

Try to change your base repo file, or whichever repo file comes up first, to a fixed URL, eg

baseurl=http://mirror.hiwaay.net/redhat/fedora/linux/core/$releasever/$basearch/os/

[Ug]

No such luck. I didn't think that would make a difference either, as when I unistalled Yum it removed those files as well.

[AndyGreen]

You uninstalled yum? Well that's easily fixed (assuming you're on FC3):

rpm -i http://mirror.hiwaay.net/redhat/fedo...fc3.noarch.rpm

[Ug]

Sorry you don't seem to understand. I have this yum problem, but it has not been fixed by me reinstalling yum. So yum is installed.

[Finalzone]

Could you provide the code of yum(/usr/bin/yum) and /usr/share/yum-cli/yummain.py, please? It will be interesting to see the problem.

[AndyGreen]

when I unistalled Yum it removed those files as well.

You're right, for some unaccountable reason I misunderstood. Apologies.

No problem, you were only trying to help.

And as requested the code for /usr/bin/yum:

#!/usr/bin/python

import sys
sys.path.insert(0, '/usr/share/yum-cli')
try:
    import yummain
    yummain.main(sys.argv[1:])
except KeyboardInterrupt, e:
    print >> sys.stderr, "\n\nExiting on user cancel."
    sys.exit(1)

And /usr/share/yum-cli/yummain.py:

It looks like some problem with the proxy url, that make some python class used bye yum fail.
have you specified a http_proxy=<Proxy server>, and what is set to ???

Try 'echo $HTTP_PROXY'

[nordicart]

It looks like your installed python package or your libxml2-python package (and through dependencies libxml2) may be broken. Those are the only python related yum dependencies which have been officially updated for FC3.

I suggest dowloading the updated packages and reinstalling them.
