Estou tentando instalar o fail2ban no CentOS, mas não consigo descobrir por que ele não será instalado:

[root@server ~]# yum install fail2ban

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest
[root@server ~]# 

    

Answer 1

É provavelmente devido a um conflito entre repos e / ou pacotes de um repositório desatualizado (ex. el5) no CentOS 6. Dê uma olhada em este tópico para obter boas dicas sobre onde começar a resolução de problemas.

Isso funcionou para mim, YMMV:

1. Encontre todos os pacotes instalados com o el5 e remova-os. Você pode encontrá-los assim:

   rpm -qa|grep el5
   

2. Remova o repositório el5

   yum repolist
   rpm -e <repo name>
   

3. Instale o repositório correto do EPEL. Se você está no CentOS 6 de 32 bits como eu:

   rpm -Uvh http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-8.noarch.rpm
   

4. Limpe o cache de yum (tente primeiro - talvez seja o suficiente):

   yum clean 
   

   ou

   yum clean expire-cache
