Estou tentando atualizar o yum, mas sem sucesso. Eu tentei todas as soluções existentes e não posso corrigi-lo Este é o erro que recebo
[root @ localhost] # atualização do yum Plugins carregados: fastestmirror, langpacks Carregando velocidades de espelhamento do hostfile em cache Não foi possível recuperar o erro link da lista de espelhos 14: curl # 7 - "Falha ao conectar-se a 2001: 1b48: 203 :: 4: 10: Rede inacessível"
One of the configured repositories failed (Unknown),
and yum doesn't have enough cached data to continue. At this point the only
safe thing yum can do is fail. There are a few ways to work "fix" this:
1. Contact the upstream for the repository and get them to fix the problem.
2. Reconfigure the baseurl/etc. for the repository, to point to a working
upstream. This is most often useful if you are using a newer
distribution release than is supported by the repository (and the
packages for the previous distribution release still work).
3. Run the command with the repository temporarily disabled
yum --disablerepo=<repoid> ...
4. Disable the repository permanently, so yum won't use it by default. Yum
will then just ignore the repository until you permanently enable it
again or use --enablerepo for temporary usage:
yum-config-manager --disable <repoid>
or
subscription-manager repos --disable=<repoid>
5. Configure the failing repository to be skipped, if it is unavailable.
Note that yum will try to contact the repo. when it runs most commands,
so will have to try and fail each time (and thus. yum will be be much
slower). If it is a very temporary problem though, this is often a nice
compromise:
yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true
Cannot find a valid baseurl for repo: base/7/x86_64
No começo eu fiz isso, mas recebi o mesmo erro
[root@localhost ]# ONBOOT=no
[root@localhost ]# dhclient
[root@localhost ]# yum update
Depois fui para /etc/yum.repos.d /
vi CentOS-Base.repo
e depois eu removi # antes da base e salvei por: xe digite
agora recebo o seguinte erro
[root@localhost yum.repos.d]# yum update
Loaded plugins: fastestmirror, langpacks

Eu também usei o seguinte comando, mas o erro foi o mesmo
yum clean all && yum clean metadata && yum clean dbcache && yum makecache && yum update -y
Para verificar o interent eu fiz o seguinte
[
root@localhost ~]# cat /etc/resolv.conf
; generated by /usr/sbin/dhclient-script
search dhcp.swmed.org
nameserver 199.242.236.1
nameserver 199.242.237.1
então eu pinguei o primeiro e recebi a mensagem seguinte
[root@localhost ~]# ping 199.242.236.1

Eu também estou enfrentando os mesmos problemas no CentOS 7.5, Depois de fazer toda a depuração, descobrimos que o Hardware Firewall está bloqueando URLs do Yum.
Depois de permitir os URLs no firewall, meu problema foi resolvido.
