Я устанавливаю свежую Cent-OS 7, но когда я хочу обновить или получить новые пакеты, я получаю
эта ошибка:

Loaded plugins: fastestmirror, langpacks
 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

после раскомментирования baseurl в CentOS-Base.repo я получил эту ошибку
еще раз, но с другим в последнем:

failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.
http://mirror.centos.org/centos/7/os/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Could not resolve host: mirror.centos.org; Unknown error"

Причина неудачи в том, что yum должен знать, что такое URL репо. В вашем конфигурационном файле у вас есть это:

#baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/

Знак # означает, что он закомментирован, поэтому yum будет игнорировать эту строку и не будет знать, какой это URL. Просто удалите хеш-знак и затем используйте yum как обычно.

Примечание . Вы должны удалить его из любого комментария baseurl , поскольку другие репозитории также важны.
