Issues with using yum

Question

We have a problem with yum on our server (Red Hat 5.7, Apache 2.2.3). If i try for example

yum update

the following error occurs:

    Loaded plugins: downloadonly, replace, rhnplugin, security
Traceback (most recent call last):
  File "/usr/bin/yum", line 29, in ?
    yummain.user_main(sys.argv[1:], exit_code=True)

Another problem is that we do not even exactly know what caused this problem. Most probably somebody updated python and changed default version some time ago (this person is not here anymore).

We found some options to repaire yum on the web, but none of them worked. Does anybody have a clue how to fix this?

Try this command: rhn_check And this if the first didnt come up with anything: rhn-profile-sync let me know if this worked. — Ilanus, Aug 14 '15 at 12:12
Please check if there was a python update as you asume: ```yum history list all``` — Tarion, Aug 14 '15 at 12:16
@Tarion, thanks, but it did not work, just as any other yum call. I get the same error — Arthur Blixem, Aug 17 '15 at 07:08
@IlanHasanov thank you for your tip. rhn_check came up with this error exceptions.NameError. — Arthur Blixem, Aug 17 '15 at 07:40
@ArthurBlixem Try yum clean all, rm -f /var/lib/rpm/__db*, rpm --rebuilddb, yum update — Ilanus, Aug 17 '15 at 07:48
@IlanHasanov yum clean all doesn't work eigher. In fact no one of yum commands works. Whatever you call with yum - you get the same error as above. — Arthur Blixem, Aug 17 '15 at 08:12

Check if you are behind a firewall, blocking connection to mirror.
Update libxml2.
Try disabling repos in /etc/yum.repos.d — some of them may cause the problem.
Try doing vi /etc/yum/pluginconf.d/fastestmirror.conf

And change this line

enable=1

to

enable=0

If none of those help. Try executing

export LD_LIBRARY_PATH=/usr/lib64:/usr/local/lib

then run

yum clean all

and test your yum. If it’s okay — add this export statement to your .bash_profile

Thanks for your tips. We have actually tried all of them except number 2. It looks like we have to recompile PHP to update libxml2, but we try to avoid recompiling, because it is a production server. – Arthur Blixem Aug 17 '15 at 12:01

The problem was not the python installation like we thought, but that the server could not access RHN. So the problem is resolved now after migrating to a new server. Thanks for everybody's help!
