The following packages have unmet dependencies:

E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

并且这种情况还在继续！
我可以在不删除 draftsight 的情况下安装 openssh-server 吗？（请注意，安装 draftsight 时我必须使用 dpkg --force-depends（它运行完美）
答案1
依赖关系损坏的原因在于您强制安装了适用于 i386 架构的 draftsight 包。显然，您使用的是 amd64 架构，因此损坏的依赖关系会阻止您安装任何其他包。
一种可能的解决方案是暂时删除 draftsight 包，然后安装 openssh-server，然后重新安装。请注意，每次更新和升级系统时都必须执行此操作。
或者，如果您可以找到适用于 amd64 架构的软件包，您可以安装它，并且我认为您的依赖关系不会再被破坏。
