Dear All,

Need your help in resolving an isue:-

I am trying to update from CentOS 5.2 ( x86_64) to CentOS 5.3. When I run the yum command, I get the following output :

After this, the process of updation aborts.
Can any one suggest why is this happening and how to solve the issue ?

Try,

Shouldn't Python be a part of the OS as YUM IIRC requires Python.

What is the output of,

The problem got solved !

I found that "yum" rpm was of CentOS 5.3 ( probably updated yum first) while the system was booting from CentOS 5.2 kernel.

Erased 5.3 yum and installed 5.2 yum.

Now seems to be working okay!

Even though they always tell you to update yum first, doing so can be problematic because of the dependency on python package versions.
