CentOS - Sep 2009 - Promlem with broken yum/rpm

Hi all,

 

I have lost/corrupted the libraries related to the expat package. This has
caused rpm and yum to stop working effectively stopping my ability to manage
my server. 

 

Recently a bug was reported by cmisare on the CentOS site that had exactly
the same symptoms http://bugs.centos.org/view.php?id=3757

 

Btw rpm crashes with exactly the same message.

 

I was hoping that cmisare, or someone else on this list, may be able to
explain to me how he/she managed to get yum working again, as must be the
case as it crashes in the first post but is working in the second post.

 

Any help would be very much appreciated.

 

Peter

Do you mean that when you run "rpm -Uvh somepackage.rpm" or even
"rpm
-qa" you get the message "libexpat.so.0: cannot open shared object
file: No such file or directory"? That is weird, because as far as I
can tell (using "ldd") the binary for "rpm" is not linked to
libexpat
at all... It also does not seem to be in the dependencies of "rpm".
Could you run the "rpm -q rpm" command and copy and paste the exact
output of it here?

A little more information about your problem would help, for instance,
what version of CentOS (4 or 5) are you running, and what is the
architecture (i386 or x86_64) of your machine? Could you please post
the exact output of the command "uname -mri" here?

One option to recover from this kind of issues is to boot the machine
in rescue mode using a CentOS install CD or the LiveCD and reinstall
the expat RPM from there. Do you have a CentOS install CD at hand that
you could use to do that?

HTH,
