Broken yum package tree

Question

I tried to update OS on my EC2 instance using yum update but I get the following error:

           Requires: python-elementtree  You could try using --skip-broken to work around the problem  You could try running: rpm

How can I fix the problem?

Thanks

P.S. I'm experienced in debian based systems but not in rpm based. This is my first rpm based server so please be tolerant.

Answer 1

Install required dependencies:

# libtermcap.so.2
wget ftp://ftp.sunet.se/pub/Linux/distributions/centos/5.5/os/x86_64/CentOS/libtermcap-2.0.8-46.1.x86_64.rpm
rpm -Uvh libtermcap-2.0.8-46.1.x86_64.rpm

# python-elementtree
wget ftp://ftp.sunet.se/pub/Linux/distributions/centos/5.5/os/x86_64/CentOS/python-elementtree-1.2.6-5.x86_64.rpm
rpm -Uvh python-elementtree-1.2.6-5.x86_64.rpm

Then try yum clean all and yum update

Answer 2

Here is what I would do.. remove python26

yum remove python26

Then update your system

yum clean all
yum update

Then if you need python 2.6 try installing it via yum
