yumdownloader 沒有安裝最新的 rpm 版本

我們安裝了 epel repo，以便在 rhel 7.x 上為 docker 下載一些 rpm

參考 - https://www.centlinux.com/2019/02/install-docker-ce-on-offline-centos-7-machine.html

yum repolist | grep epel
epel/x86_64               Extra Packages for Enterprise Linux 7 - x86_64  13,257

現在我們要下載一些所需的 rpm 作為

yumdownloader --resolve libseccomp
Loaded plugins: langpacks, product-id
--> Running transaction check
---> Package libseccomp.i686 0:2.2.1-1.el7 will be installed
---> Package libseccomp.x86_64 0:2.2.1-1.el7 will be reinstalled
--> Finished Dependency Resolution

ls -ltr | grep libseccomp


ls -ltr | grep libseccomp
-rw-r--r-- 1 root root    50612 Nov 10  2016 libseccomp-2.2.1-1.el7.x86_64.rpm
-rw-r--r-- 1 root root    48972 Nov 10  2016 libseccomp-2.2.1-1.el7.i686.rpm

但是我們很驚訝yumdownload沒有下載最新版本

• ( http://www.linuxfromscratch.org/blfs/view/svn/general/libseccomp.html )

為什麼yumdownloader-，不下載最新的rpm版本？

注意 - 我們想要最新版本的原因是：

該libseccomp軟體包是 RHEL 而不是 EPEL 的一部分，因此一旦您向訂閱管理器註冊，您將從 RHEL 儲存庫下載它。RHEL 7 中的版本是 libseccomp-2.3.1-4.el7。
