yum upgrade -y我尝试使用以下说明从 Rocky 8.6 升级（在我通过 更新所有软件包后现在是 8.7 ）：
https://www.techrepublic.com/article/upgrade-rocky-linux/
REPO_URL="https://download.rockylinux.org/pub/rocky/9/BaseOS/x86_64/os/Packages/r"
RELEASE_PKG="rocky-release-9.0-2.4.el9.noarch.rpm"
REPOS_PKG="rocky-repos-9.0-2.4.el9.noarch.rpm"
GPG_KEYS_PKG="rocky-gpg-keys-9.0-2.4.el9.noarch.rpm"
然后 ：
sudo dnf install $REPO_URL/$RELEASE_PKG $REPO_URL/$REPOS_PKG $REPO_URL/$GPG_KEYS_PKG
结果显示如下信息：
[root@rocky ~]# dnf install $REPO_URL/$RELEASE_PKG $REPO_URL/$REPOS_PKG $REPO_URL/$GPG_KEYS_PKG

错误提示我正在安装 8.6，而我安装的是 9.x。这里可能存在什么问题？
答案1
我认为您需要在 dnf 安装命令行中添加 epel-release 和 remi-release 包。
所以：
https://dl.fedoraproject.org/pub/epel/epel-release-latest-9.noarch.rpm
https://rpms.remirepo.net/enterprise/remi-release-9.rpm
