我在 ProtonMail 有一个 PRO 帐户，我想将其用于我的 Web 服务器。我在这里找到了一个教程：
https://pychao.com/2018/10/13/use-protonmail-bridge-on-headless-linux-machines/#comment-6612
在我的服务器上，我尝试了以下命令行：
$ sudo apt install pass
$ wget -c https://protonmail.com/download/protonmail-bridge_1.2.7-1_amd64.deb
$ sudo dpkg -i protonmail-bridge_1.2.7-1_amd64.deb
$ sudo apt update
$ sudo apt install protonmail-bridge
但我遇到了错误：
ubuntu@www-example-com ~ $ sudo dpkg -i protonmail-bridge_1.2.7-1_amd64.deb

protonmail-bridge is already the newest version (1.2.7-1).
You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
protonmail-bridge : Depends: qt5-default but it is not going to be installed
Depends: libqt5designer5 but it is not going to be installed
Depends: libqt5multimediawidgets5 but it is not going to be installed
Depends: libqt5quickwidgets5 but it is not going to be installed
Depends: libpulse-mainloop-glib0 but it is not going to be installed
Depends: libsecret-1-0 but it is not going to be installed
Depends: ttf-dejavu but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
如何在 Ubuntu Server 20.04 上安装 ProtonMail？
答案1
手动安装软件包时，可能会出现这样的错误，这是因为你的系统中没有安装依赖项。
要修复此问题，您需要按建议进行操作：
$ sudo apt --fix-broken install
这应该安装缺少的依赖项并解决您的问题。
答案2
检查此链接是否有帮助。它将跳过依赖项步骤。
我可以在按照以下链接后在 Kali 上执行桥接。
