Hi, I have one centOS 4.4 with apache and some services. I want to
upgrade to version 5 running:

Yum -y -c /etc/yum.repos.d/base_centos upgrade 

Where the file bases_centos has:

[base]
name=CentOS-5 - Base
baseurl=ftp://repository.mydomain/centos/5/os/i386
gpgcheck=0
timeout=1800

And, repository.mydomain is a mirror of mirror.centos.org

It began to download all headers until I get this error:

Error: Missing Dependency: libnewt.so.0.51 is needed by package
crypto-utils
Error: Missing Dependency: libnewt.so.0.51 is needed by package
newt-perl

Any ideas?
