Hi,guys. I have encounter a Yum issue on my Centos5.3 64bit VPS. The day before yesterday, when I try to use yum to install a sw. Then I found the yum cannot work. such like this:

Use the "yum install" or "yun update" only get the following output:

[root@li72-114 ~]# yum update
Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
* addons: ftp.usf.edu
* base: mirrors.netdna.com
* extras: mirrors.netdna.com
* rpmforge: apt.sw.be
* updates: centos.omnispring.com

---------------------------------------
I have googled this issue. Some post suggest reinsatll the libxml2. Such like this website:
http://webhostingneeds.com/Yum_error_Ty ... _not_found

But follow this link, I cannot find the libxml2-cvs-snapshot.tar.gz
on ftp://xmlsoft.org/ . So I install a libxml2-2.7.2 . But it cannot solve the issue.


Any one have encounter this same issue . Or anyone have solve this issue . Please give me a powerful help hand. Thanks.

try 'yum clean all'
try unsetting the LD_LIBRARY_PATH environment variable
try getting the official libxml2 packages from CentOS 5.5 and installing them with rpm -Uvh
try getting the latest yum from CentOS 5.5 and installing it with rpm -Uvh

Thanks for Alucard, I'll try late.
