以下软件包具有未满足的依赖项：unifi

Question

我在相当不受支持的机器上安装了 Unifi：

root@EvoWebsites:/home/pklys# apt-get upgrade
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
 unifi : Depends: mongodb-server (< 1:3.6.0) but 1:3.6.3-0ubuntu1 is installed or
                  mongodb-10gen (< 3.6.0) but it is not installable or
                  mongodb-org-server (< 3.6.0) but it is not installable
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

现在，虽然我能够管理 Unifi 的 ugprades（依赖项并不是很严格），但我无法再对剩余的软件包使用 apt upgrade。

有没有办法“跳过” unifi 和它的依赖项升级，因为我已经手动升级了 Unifi 并告诉 apt upgrade 其他所有内容而忽略 Unifi 在说什么？

我试过的：

    root@EvoWebsites:/home/pklys# apt-mark hold unifi
unifi was already set on hold.

澄清。最终目标是升级除 UNIFI 和 MongoDB 之外的所有内容。Ubiquiti 的最新升级增加了对 mongodb 3.4 的 UNIFI 的依赖。如果你像我一样升级到 18.04，你会得到 3.6，这会破坏 Unifi。为了解决这个问题，我卸载了 Unifi，重新安装了 Unifi 并从备份中获取了配置，它在 3.6+ mongodb 上运行良好。我的猜测是 Ubiquiti 没有为其余用户自动执行此过程，因此为了稳定发布，他们添加了此依赖项。

现在因为我已经升级了，所以我需要让我的机器保持最新状态。所以现在我需要跳过 Unifi 升级（我直接从 dpkg 安装它们并跳过依赖项），但继续升级其他东西。

希望它能解释原因和最终目标。

虽然所有好的答案我都选择了不同的方法。为什么要修复 Ubuntu 而我可以修复 Unifi 包！

全文在这里：https : //evotec.xyz/ubuntu-18-04-fixing-unifi-deb-package-to-run-with-3-6-mongodb/

但是思路是下载包，解包

cd /home/username
wget https://dl.ubnt.com/unifi/5.9.29/unifi_sysvinit_all.deb
mkdir tmp
dpkg-deb -R unifi_sysvinit_all.deb tmp

查找DEBIAN\control文件并简单地从 Depends 部分删除第 7-8 行。

重新打包后：

dpkg-deb -b temporary unifi-fixed.deb
dpkg-deb: building package 'unifi' in 'unifi-fixed.deb'.

只需安装dpkg -i unifi-fixed.deb. 安装后apt update，apt upgrade工作！
