Erro de atualização do Yum no CentOS 5.6

Question

Eu tenho o CentOS 5.6 no meu laptop.

Quando digito yum update , recebo o erro abaixo:

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. Invalid release/
removing mirrorlist with no valid mirrors: /var/cache/yum/base/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: base

Abaixo está o meu arquivo /etc/yum.repos.d/CentOS-Base.repo (não mudei nada nele):

Por que não consigo atualizar meu CentoOS para o 5.11?
Anteriormente, consegui atualizar o CentOS para o 5.11 sem problemas.
Alguém pode me ajudar?

    

Answer 1

O CentOS-5 chegou ao fim da vida em 31 de março de 2017. Isso significa que nenhuma nova atualização será lançada pela Red Hat. A atual árvore 5.11 que você procura foi movida para vault.centos.org .

Para obter acesso à ramificação 5.11, edite /etc/yum.repos.d/CentOS-Base.repo e comente as diretivas mirrorlist . Além disso, em cada seção ativada, adicione baseurl=http://vault.centos.org/5.11/os/$basearch ou baseurl=http://vault.centos.org/5.11/updates/$basearch apropriadamente. Por exemplo, para um base repo que se parece com:

[base]
name=CentOS-$releasever - Base
mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

... mude para:

[base]
name=CentOS-$releasever - Base
# mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os
baseurl=http://vault.centos.org/5.11/os/$basearch
gpgcheck=1
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-5

    

Answer 2

Versão atualizada e testada (a partir desta data de postagem) do /etc/yum.repos.d/CentOS-Base.repo para o Centos 5.11 (final):

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#
#
