我搜索了整个互联网，包括阅读 google/askubuntu/所有 ubuntu 社区上的所有内容），尝试了所有可能的解决方案，但仍然没有找到答案（但我不是 google，所以我的索引和搜索算法技能可能不是那么好）
无论如何，我正试着跑步apt-get update，然后apt-get upgrade。
我收到以下错误：
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:
libnvidia-ifr1-390 : Depends: libnvidia-gl-390 but it is not installed
libnvidia-ifr1-390:i386 : Depends: libnvidia-gl-390:i386 but it is not installed
nvidia-driver-390 : Depends: libnvidia-gl-390 (= 390.87-0ubuntu0~gpu18.04.1) but it is not installed
Recommends: libnvidia-gl-390:i386 (= 390.87-0ubuntu0~gpu18.04.1)
E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
然后我跑了apt --fix-broken install..得到了这些结果

我尝试了网上找到的所有技巧，例如apt clean/ remove/ dist upgrade/ 等等，但都没有成功。apt
非常感谢任何帮助。

我之前遇到了同样的错误，并使用名为 的包修复了它aptitude。
运行这个sudo apt install aptitude
然后运行sudo aptitude upgrade
它将为您提供可能的解决方案，忽略第一个并使用第二个。
希望这对你也有用。
