我正在尝试将 xargs 安装在运行 openjdk:17-oracle 的容器中，但我无法确定此映像中存在什么包管理器。
FROM openjdk:17-oracle
RUN apt-get install findutils
抛出错误：
=> ERROR [stage-1 4/4] RUN apt-get install findutils 0.5s

> [stage-1 4/4] RUN apt-get install findutils:
#13 0.395 /bin/sh: apt-get: command not found
-
yum install findutils和其他几个一样。
我需要 xargs，因为 gradle runner 使用它来为我的 java 进程构建“执行”命令。

我正在尝试在 Oracle Linux Server 7.9 上安装 snapd 在许多站点上，我看到建议按如下方式安装 spand
sudo yum install epel-release
sudo yum -y install snapd
但我无法在 Oracle Linux 上安装此存储库（没有可用的软件包 epel-release。）系统中提供了以下存储库
ol7_MySQL80/x86_64
ol7_UEKR6/x86_64
ol7_addons/x86_64
ol7_developer_php74/x86_64
ol7_ksplice
ol7_latest/x86_64
ol7_oci_included/x86_64
ol7_optional_latest/x86_64
ol7_software_collections/x86_64
谁能告诉我如何在 Oracle Linux 7.9 上安装 snapd？
我们正在发现 Oracle Linux 并考虑从其他 RHEL 克隆迁移。
一个尚未解决的问题是：Oracle Linux 上的次要版本的生命周期是什么？当新的积分版本可用于以前的版本时，我们是否会在免费层上获得更新？
示例：我需要安装 Enterprise Linux 7.7 服务器，在 CentOS 世界上，我们需要从 CentOS Vault 获取 ISO，并且只有在 CentOS 7.8 发布前的最后一天更新。另一方面，在 RHEL 上，即使 RHEL 7.8 已经发布了一段时间，也会有一些针对 RHEL 7.7 的安全更新。所以在这种情况下，RHEL 比 CentOS 更适合。
那么在这种情况下，Oracle Linux 的政策是什么？我在哪里可以读到它？我如何固定 Oracle Linux 以保持一个点版本并像在 RHEL 中一样对其进行修补？
谢谢你们。
目前正在运行 Oracle Linux v7.9，有没有办法升级到 Oracle Linux v8.3（或任何 v8.x）作为就地升级而无需从新的 VM 安装？
如何在 Oracle Linux 中使用 Apache 安装/配置 PHP 8？
我在 Oracle Linux 中找不到与 PHP 8 相关的存储库。
到目前为止我尝试的是：
sudo dnf install httpd如何链接两者？
现在，当我打开一个网站时，它显示的是 PHP 代码而不是执行它。
如何手动使用 Apache 配置 PHP？
我应该安装哪些软件包？
System Configuration:
Virtual Box version: VirtualBox-6.1.6-137129-Win
Host OS: Windows 10
Guest OS: Oracle Linux 8.1 (Virtual Box Guest Additions not installed in it yet)
VPN Software running on Host OS (Windows 10):
Cisco AnyConnect Secure Mobility Client
Version: 4.8.02045
Preferences of VPN Client: Screen Shot Attached
Internet Connectivity on Host OS is through WiFi interface Intel(R) Wireless-AC 9560 160MHz connected to my Home router.
我已经配置了 Guest VM，即 Oracle Linux，只有 1 个 NAT 网络接口（默认设置未修改），当主机未连接到 VPN 时，我的 Guest VM，即 Oracle Linux 能够使用主机网络，即我能够从甲骨文Linux。
现在我认为我将从主机操作系统（即 Windows 10）和我的客户操作系统（即 Oracle Linux）连接到 VPN连接来宾操作系统既不能使用任何 VPN 资源，也不能使用 Internet。似乎没有任何工作。VPN连接后，我尝试在Oracle Linux机器上进行wireshark转储，但wireshark中没有任何内容完全空白。
在主机（即 Windows 10）上执行的路由打印命令输出也在 VPN 连接后附加。
还附加了 VBox.log 文件
我尝试解决问题的程序：
下面的命令集体和一个接一个地执行，但问题仍然存在：
C:\Program Files\Oracle\VirtualBox> VBoxManage modifyvm "VM name" --natdnshostresolver1 on
C:\Program Files\Oracle\VirtualBox> VBoxManage modifyvm "VM name" --natdnsproxy1 on
C:\Program Files\Oracle\VirtualBox> VBoxManage setextradata global VBoxInternal2/HostDNSSuffixesIgnore 1
尝试在访客操作系统（Oracle Linux）中直接安装 Cisco AnyConnect，它显示它已连接但仍然无法访问 Internet 或任何 VPN 站点。
如果我将 Oracle Linux VM 网络适配器配置为桥接，那么当 VPN 在 Windows 主机上连接时，我至少在 Oracle VM 上有 Internet 连接，但目标是使用与主机系统（即 Windows 10）连接的相同 VPN 连接。
关于这个问题的任何帮助都会很棒。
所有日志都可以从此链接下载。
我正在尝试通过expdep在 oracle 数据库上运行模式导出：
expdp somedatabase/something directory=EXP_DIR schemas=someschema dumpfile=dumpfile.dmp logfile=logfile.log
上面的命令（尽管为了发布这个问题而进行了编辑）之前一直在工作，但现在我收到了这个错误：
ORA-31626: job does not exist
ORA-31633: unable to create master table "SOMEDATABASE.SYS_EXPORT_SCHEMA_09"

我有理由相信，根本原因是存在与早期数据泵相关的停滞作业，这些作业被半中止 (ctrl+c) 并删除了目标文件。
如何清除这些作业，以便我可以从头开始重新启动数据泵？
从外观上看，我在 Centos 上运行的是 12.2.0.1 版本。
