我正在尝试升级和修补 CVE 2016-2017，在此过程中，我收到了有关依赖项的错误。我尝试解决这些问题，但我有点新手，当我尝试修复依赖项问题时，我得到了额外的依赖项。我正尝试根据我读过的几本指南来做到这一点。
如果我跑
sudo apt-get install --only-upgrade libssl1.0.0 openssl
我明白了
Reading package lists... Done
Building dependency tree
Reading state information... Done
openssl is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
grub-pc : Depends: grub2-common (= 1.99-21ubuntu3.18)
Depends: grub-pc-bin (= 1.99-21ubuntu3.18)
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).
我希望有人能帮助我解决这个问题。
谢谢！

最后更新
在@db429 的帮助下，我找到了问题的根源。我有一些需要删除的坏 PPA。删除后，我必须删除 grub-pc，然后更新，然后重新安装 grub。
到那时，我就能让一切按预期进行。
答案1
好的，你继承了一个相当不错的建筑工地。
到目前为止，我们有 4 个问题需要解决：未满足的 grub 依赖项、sources.list 中不存在的 ppa、rackspace 存储库缺少 gpg-key 以及 100 个等待的更新。
- 首先。运行时出现 404
sudo apt-get update是因为该存储库不再存在。您可以找到有关存储库的更多信息这里。因此，我们必须在源列表中将其注释掉。打开相应的文件sudo nano /etc/apt/sources.list- 您也可以使用 vim。找到以 开头的三行http://ppa.launchpad.net/ondrej/php5/...并在其前面添加#- 保存文件。也许它是 /etc/apt/sources.list.d/ 中的一个文件 - 不确定，4 年前我用过 12.04 - 程序保持不变。 - 现在让我们添加同一个程序员的当前 ppa
sudo add-apt-repository ppa:ondrej/php（如果你的系统运行的是 php5.4，请使用sudo add-apt-repository ppa:ondrej/php5-oldstable- 参见这里）。这将在添加 gpg-key 和存储库后更新存储库 - 如果出现W: GPG error:让我们暂时忽略它。 - 在升级其他 100 个之前，我们首先必须解决 grub 问题 - 因此我们将卸载
sudo apt-get remove grub-common并重新安装它们sudo apt-get install grub-pc- 包的差异是由于依赖关系造成的；所有 grub 包都依赖于 grub-common，而 grub-pc 将它们全部拉回来。 如果到目前为止我们没有遇到任何新问题，让我们去更新所有这 100 个软件包。让我们开始使用
sudo apt-get dist-upgrade，我们使用 dist-upgrade 而不是 upgrade，因为它更聪明 ;) - 参见这里。可能需要重复此操作几次。对于 pgp-keyhttp://stable.packages.cloudmonitoring.rackspace.com存储库最好联系他们，因为我在标准密钥服务器上的任何地方都找不到他们的密钥。可以找到让您的系统识别密钥的过程这里——直到那时才有
sudo apt-get upgrade --allow-unauthenticated可能解决这个最后的堡垒。
