我有一个复杂的 systemd 目标单元，其中包含许多依赖单元。我想列出并解析这些状态，而不会退回到循环中。

'list-dependencies' 子命令仅以（彩色，不以纯 unicode 复制）点的形式给出状态，这不是很好解析。

> systemctl list-dependencies --no-page myunit.target
dcache.target
● ├─mytemplate@unit_foo.service
● ├─mytemplate@unit_bar.service
● ├─mytemplate@unit_baz.service
...

--no-page 标志似乎没有任何影响，并且无论有无输出都保持不变。

或者，

systemctl list-dependencies --plain myunit.target

仅列出依赖项但不列出其当前状态

有没有办法从'systemctl list-dependencies'生成输出，可以解析或者是JSON或类似的？

dependencies systemd systemctl

我只是想在我的 Amazon Linux 2 实例上安装 OLS，但我在开始和所有最后步骤都收到了错误。以下是关于：

  1. 当我添加指南存储库推荐时，我收到错误：

     failure: repodata/repomd.xml from litespeed: [Errno 256] No more mirrors to try.

    http://rpms.litespeedtech.com/centos/8/x86_64/repodata/x86_64/repodata/repomd.xml：[Errno 14] HTTP 错误 404 - 未找到

要修复它，我只需在链接http://rpms.litespeedtech.com/centos/$releasever/$basearch/处将 $releaseserver 替换为 8（我可以在http://rpms.litespeedtech.com/centos/看到） 并且......它有效！但在那之后，当我尝试安装时，我收到这些依赖错误：

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

我不知道如何解决它。感谢您的回复。

多年来，我作为爱好者管理员解决了许多依赖关系问题：我只是删除了一些包，直到整个事情得到解决，或者（如果后果会很大）等到问题自行解决。

# cat /etc/centos-release
CentOS Linux release 7.8.2003 (Core)

现在我想了解以下内容的含义：

# yum update

我想系统ImageMagick.x86_64将从0:6.7to更新，0:6.9但它无法做到。然后我的猜测：删除0:6.7会删除libMagickCore.so.5，但最后一个是需要的php72w-pecl-imagick-3.4.3-1.2.w7.x86_64……那为什么不直接留libMagickCore.so.5在系统中呢？可能是因为需要一个新的，但我看不出是哪一个......

我真的不明白幕后发生了什么。

我正在尝试使用 Python 2.7.9 将 Certbot 从 0.10.2 更新到支持 Debian 9.1 中的 ACME 2 的某个版本。

任何想法？这是一个生产服务器。

编辑：

所以显然我已经在 Debian 9 中安装了一些来自 Debian 10 的软件包。因为我不能用 apt 做任何事情，所以我试图用 aptitude 解决依赖关系。

(venv)root@deb64:/home/x/# aptitude -V -s install libc6-dev=2.24-11+deb9u4
The following packages will be DOWNGRADED:
  libc6-dev{b} [2.28-10 -> 2.24-11+deb9u4]
The following packages will be REMOVED:
  libc-dev-bin{u} [2.28-10]
The following packages will be upgraded:
  libc6 [2.24-11+deb9u1 -> 2.24-11+deb9u4]  linux-libc-dev [4.9.30-2+deb9u5 -> 4.9.210-1]
The following partially installed packages will be configured:
  libc-l10n  locales{b}  man-db
2 packages upgraded, 0 newly installed, 1 downgraded, 1 to remove and 235 not upgraded.
Need to get 6,539 kB of archives. After unpacking 3,561 kB will be freed.
The following packages have unmet dependencies:
 libc6-dev : Depends: libc-dev-bin (= 2.24-11+deb9u4) but it is not going to be installed
 locales : Depends: libc-bin (> 2.28) but 2.24-11+deb9u1 is installed and it is kept back
The following actions will resolve these dependencies:

     Remove the following packages:
1)     locales [2.28-10 (now)]
2)     task-english [3.39 (now, oldstable)]

     Install the following packages:
3)     locales-all [2.24-11+deb9u4 (oldstable)]

     Upgrade the following packages:
4)     postgresql-9.4 [9.4.13-0+deb8u1 (now) -> 9.4.26-2.pgdg90+1 (stretch-pgdg)]
5)     postgresql-9.6 [9.6.4-0+deb9u1 (now) -> 9.6.18-1.pgdg90+1 (stretch-pgdg)]
6)     postgresql-contrib-9.4 [9.4.13-0+deb8u1 (now) -> 9.4.26-2.pgdg90+1 (stretch-pgdg)]
7)     postgresql-contrib-9.6 [9.6.4-0+deb9u1 (now) -> 9.6.18-1.pgdg90+1 (stretch-pgdg)]

     Downgrade the following packages:
8)     libc-dev-bin [2.28-10 (now) -> 2.24-11+deb9u4 (oldstable)]

Accept this solution? [Y/n/q/?] q

如果我接受此解决方案，系统是否安全？

这是 Debian-10.4 的全新安装。sources.list 文件如下：

我什至不会去想象什么样的发行版不提供作为基本安装的一部分的安全远程访问。无论 Debian 的原因是什么，我都需要这样。问题似乎是这样的：

 openssh-server : Depends: openssh-client (= 1:7.9p1-10+deb10u1) but 1:7.9p1-10+deb10u2 is to be installed

如何强制安装损坏的依赖项？

我正在尝试使用 mozjpeg 作为 jpeg-turbo 的替代库。我完全能够获取源代码并根据需要对其进行编译，甚至可以从中创建一个 deb 文件，我可以使用它来安装包（例如apt-get install ./mozjpeg_3.2_amd64.deb）。

为了清楚起见，请注意这两个包应该提供完全相同的接口，因此在功能上是等效的。因此，mozjpeg 应该满足对 jpeg-turbo 的依赖。

好的，继续，当我继续安装依赖包（例如 ghostscript 开发头文件libgs-dev）时，我遇到了错误，因为它们声明了对libjpeg62-turbo-dev：

dpkg: error processing archive /tmp/apt-dpkg-install-HuzNRO/0-libjpeg62-turbo-dev_1%3a1.5.1-2_amd64.deb (--unpack):
trying to overwrite '/usr/include/jerror.h', which is also in package mozjpeg 3.2-20170219

现在，在这一点上出现冲突当然是合乎逻辑的。有没有办法防止这种情况？我可以告诉依赖系统 mozjpeg 满足对 jpeg-turbo 的依赖，以便任何依赖 jpeg-turbo 的包都将使用替​​换安装吗？

提前致谢。

运行时出现以下错误puppet-lint：

$ puppet-lint manifests/*
manifests/init.pp - WARNING: class inheriting from params class on line 72

我在duckduckgo.com上快速搜索了一下，得到了这个：

http://puppet-lint.com/checks/class_inherits_from_params_class/

但是，我们的 Puppet Agent 版本都是 2.7 或更高版本，我们的 Puppet Master 都是 3.0 或更高版本。

作为参考，有init.pp问题的代码如下：

class myclass (
    $zone = 'top',
    $::myclass::params::base_url,
    $::myclass::params::username,
) inherits myclass::params {
...

中的代码params.pp如下：

class myclass::params {
    $base_url  = hiera('myclass::base_url','https://beta.tpsreports.com/coversheets/')
    $username = hiera('clap::base_url','prod')
}

即使 Hiera 查找失败，我仍然不应该收到这样的错误：

err: Could not retrieve catalog from remote server: Error 400 on SERVER: Must pass ::myclass::params::base_url to Class[Myclass] at /etc/puppet/manifests/nodes/beta_servers_0.pp:126 on node beta-web-server-0.tpsreports.com

既然我已经讨论了一些背景，我非常愿意添加，如果有人问，我的问题如下：

  1. 如果params即使 hiera 查找以某种方式失败，我的类也会提供参数，为什么我会收到此错误？
  2. 我是否必须使用可怕的解决方法（即 puppet-lint.com 链接中的“你应该做的事情”，即使我的 Puppet 版本高于2.6.2所有情况？

我正在尝试安装特定版本的 MySQL：mysql-community-server-5.6.29-2.el6在 RedHat 6.6 上。

当我运行时yum install，我得到依赖错误，但依赖显然是可用的。我不确定如何进行。

看起来有些东西在请求MySQL-community-libs-5.7.11-1.el6，但我不知道如何强迫它不要。

有用的输出：
