Atualmente, estou executando o RHEL Server 7.2 e toda vez que um comando executar um yum (mesmo coisas básicas como atualização, instalação, instalação local, etc.) eu recebo o seguinte erro:
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. Disable the repository, 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>
4. 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 retrieve metalink for repository: epel/x86_64. Please verify its path and try again
Eu li que uma maneira de corrigir isso era alterar todas as instâncias de "https" para "http" em /etc/yum.repos.d/epel.repo, mas isso não funcionou para mim. Eu também tentei atualizar os Certificados SSL sem sorte. Alguma ideia? Obrigado!
-Editar Este é um terminal na minha escola (Penn State Berks). É uma das poucas configurações de caixas de linux no campus, então há pouco ou nenhum suporte para isso. É a configuração do meu projeto de pesquisa de graduação, então eu e o professor somos os únicos que o utilizaram. Todas as configurações de rede, incluindo as configurações de DNS, foram configuradas anteriormente pela escola.
-Editar Eu tentei executar o comando yum update, mas com o repositório epel desativado e este foi o resultado:

Oi
Você tentou desativar seu repositório epel, que parece ser o repositório problemático?
yum update --disablerepo=epel/x86_64
yum update --disablerepo=epel
Se funcionar melhor, sua configuração do epel está errada, pode ser que você possa excluí-la e reinstalá-la
rm -f /etc/yum.repos.d/epel*
yum remove epel-release
yum install epel-release
