在过去几天里，我已经从 debian 8、9 升级到 10。在此过程中的某个时刻，apt 停止运行，因为它无法升级 gnuplot 包（我确信我一开始就不会使用它）。我快要抓狂了，因为我已经搜索解决方案一段时间了。

You might want to run 'apt --fix-broken install' to correct these.
The following packages have unmet dependencies:
gnuplot-nox : Depends: gnuplot-data (= 5.2.6+dfsg1-1+deb10u1) but 4.6.6-2+deb8u1 is installed
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).

此外，我认为这与此无关，但可能值得一提，我的内核无法升级（可能是因为 apt 损坏）。我会在以后寻找解决方案，以免偏离原先的问题。

我的 apt 缓存中显示 linux 标头 5.6 和 5.7。我认为损坏的 gnuplot 不允许我升级？有什么提示吗？我在升级之间重启了好几次。我真的很想把整个包都删除，然后让 apt 再次工作

简而言之：
dpkg -i --force-overwrite “文件”
apt-get 安装 -f
