我在具有根存取權限的專用伺服器上。對伺服器不熟悉。我正在嘗試在我的伺服器上安裝 FFMpeg。我遇到錯誤，不知道如何解決。因此，任何對此的了解都將非常感激。

One of the configured repositories failed (DAG RPM Repository),
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 dag
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=dag.skip_if_unavailable=true
failure: repodata/repomd.xml from dag: [Errno 256] No more mirrors to try.

這是舊的 DAG 儲存庫，基本上已經過時了。您應該刪除它，方法是刪除最初安裝的存儲庫安裝包，或者enabled=0在/etc/yum.repos.d.
EL7 儲存庫位於AT轉速有FFmpeg 的構建。它們相當舊，但可能適合大多數用途。
如果您想要最新最好的，您可能必須從原始碼建立它。如今這並不是特別困難。
