我想从我的系统中彻底删除 emacs25 并保留 emacs26。不幸的是，我陷入了修复失败的状态
这是输出...
尝试删除 emacs25

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
emacs : Depends: emacs25 or
emacs25-lucid but it is not going to be installed or
emacs25-nox but it is not going to be installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
好的，让我们尝试修复损坏的安装...
