dnf copr 插件不存在于 dnf-plugins-core 中

dnf我想使用和安装包copr。copr-cli和dnf-plugins-core都已安装。 但dnf显示copr不存在：

$> sudo dnf install dnf-plugins-core
Using metadata from Wed Jan 18 12:48:19 2017
Package dnf-plugins-core-0.1.5-3.el7.noarch is already installed, skipping.
Package dnf-plugins-core-0.1.5-3.el7.noarch is already installed, skipping.
Dependencies resolved.
Nothing to do.

$> sudo dnf copr (stuff)
No such command: copr. Please use /usr/bin/dnf --help
It could be a DNF plugin command.

dnf-plugins-copr尝试自行安装也会失败：

$> sudo dnf install dnf-plugins-copr
Using metadata from Wed Jan 18 12:48:19 2017
No package dnf-plugins-copr available.
Error: no package matched: dnf-plugins-copr

我必须先启用其他存储库吗？我正在使用 RHEL 7.3。

事实上，在 CentOS 7 上，DNF 在 EPEL7 仓库中太旧了（版本 0.6.x）。按照这些说明操作；它们将解决问题。 来源：适用于 RHEL 7 和 CentOS 7 的 Fresh DNF

摘自此博客：

为了在 RHEL 7 或 CentOS 7 中获取 DNF-1.1.9：启用 EPEL 存储库以获取其他 DNF 依赖项：

# wget https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
# sudo rpm -Uvh epel-release-latest-7*.rpm

添加 DNF 堆栈存储库：

# cat <<EOF > /etc/yum.repos.d/dnf-centos.repo
[dnf-centos]
name=Copr repo for dnf-centos owned by @rpm-software-management
baseurl=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-centos/epel-7-\$basearch/
skip_if_unavailable=True
gpgcheck=1
gpgkey=https://copr-be.cloud.fedoraproject.org/results/@rpm-software-management/dnf-centos/pubkey.gpg
enabled=1
enabled_metadata=1
EOF

安装 DNF：

# yum install dnf

检查您是否拥有正确的版本：

# dnf --version
1.1.9
