Como todos sabeis el fin del ciclo de vida (EOL) de centos 7 llego el 30 de junio de 2024.
La recomendación es migrar el sistema operativo a una versión nueva, pero por diversos motivos puede no interesarnos.
El problema es que al seguir con centos 7 los repositorios han dejado de funcionar y al intentar instalar alguna libreria con yum nos aparecen los siguientes errores:
http://ftp.cica.es/CentOS/7.9.2009/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.
To address this issue please refer to the below wiki article
https://wiki.centos.org/yum-errors
If above article doesn't help to resolve this issue please use https://bugs.centos.org/.
http://ftp.dei.uc.pt/pub/linux/CentOS/7.9.2009/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.
http://mirror.uv.es/mirror/CentOS/7.9.2009/os/x86_64/repodata/repomd.xml: [Errno 14] HTTP Error 404 - Not Found
Para no tener esos errores y poder seguir instalando librerías con yum solo tenemos que cambiar los repositorios.
Primero borramos todos los repositorios del sistema o los que nos estén dando errores:
rm /etc/yum.repos.d/*
Para a continuación añadir los siguientes ficheros:
