CentOS 7 Не удается найти действительный baseurl для репозитория: base / 7 / x86_64 при обновлении yum

Эта ошибка сводит меня с ума, я пробовал все, что размещено на форумах, и ничего не работает.

Когда я печатаю:

# yum update

Я получаю следующую ошибку:

[root @ www yum.repos.d] # yum update Complementos cargados: fastestmirror Загрузка скоростей зеркала из кэшированного файла хоста Не удалось получить зеркальный список http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock Ошибка была 14 : curl # 56 - «Ошибка записи: сброс соединения удаленным компьютером»

Ошибка одного из настроенных репозиториев (Неизвестно), и yum не имеет достаточно кэшированных данных для продолжения. На данный момент единственная безопасная вещь, которую может сделать Yum - это потерпеть неудачу. Есть несколько способов исправить это:

 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

Это рабочий сервер с собственным IP-адресом, поэтому я не пробовал включать DHCP и ONBOOT = нет (у меня есть да) и т. Д.

Если я наберу:

# curl -v 'http://mirrorlist.centos.org/?repo=os&arch=x86_64&release=7'

Вот что я получаю:

[root@www yum.repos.d]# curl -v 'http://mirrorlist.centos.org/?repo=os&arch=x86_64&release=7' * About to connect() to mirrorlist.centos.org port 80 (#0) * Trying 2001:1b48:203::4:10... * Connected to mirrorlist.centos.org (2001:1b48:203::4:10) port 80 (#0) > GET /?repo=os&arch=x86_64&release=7 HTTP/1.1 > User-Agent: curl/7.29.0 > Host: mirrorlist.centos.org > Accept: */* > * Recv failure: Connection reset by remote machine * Closing connection 0 curl: (56) Recv failure: Connection reset by remote machine

If you don't like this checking # interupting your command line usage, it's much better to have something # manually check the metadata once an hour (yum-updatesd will do this). # metadata_expire=90m  # PUT YOUR REPOS HERE OR IN separate files named file.repo # in /etc/yum.repos.d 

Как я могу сделать yum updateработу снова ???
