我在 apt upgrade 后遇到问题并收到以下消息：
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).
之后我尝试 apt --fix-broken install，但得到：
dpkg-divert: error: mismatch on package
when removing 'diversion of /usr/lib/i386-linux-gnu/libGL.so.1 by libnvidia-gl-390'
found 'diversion of /usr/lib/i386-linux-gnu/libGL.so.1 to /usr/lib/i386-linux-gnu/libGL.so.1.distrib by nvidia-340'

E: Sub-process /usr/bin/dpkg returned an error code (1)
然后我尝试解决方案 如何修复 ubuntu 18.04 LTS 上的这个 apt 问题？
sudo rm /var/cache/apt/archives/libnvidia-gl-390_390.87-0ubuntu0~gpu18.04.1_i386.deb
sudo rm /var/cache/apt/archives/libnvidia-gl-390_390.87-0ubuntu0~gpu18.04.1_amd64.deb
然后删除缓存中的所有下载文件。
sudo apt-get clean
sudo apt-get autoremove && sudo apt-get autoclean
我再次得到：
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

E: Unmet dependencies. Try 'apt --fix-broken install' with no packages (or specify a solution).
我三周前将 ubuntu 从 16.04 版本更新到 18.04 - 但这个问题两天前就出现了。
有人可以帮忙吗？
答案1
它很可能没有正确安装。我可能会删除没有依赖项的软件包，如下所示：
sudo dpkg -r libnvidia-ifr1-390
sudo dpkg -r libnvidia-ifr1-390:i386
sudo dpkg -r nvidia-driver-390
使用这些命令应该释放 apt-get，现在您可以安装依赖项并重新安装驱动程序：（这应该会自动安装依赖项）
sudo apt-get install nvidia-driver-390
如果同样的事情再次发生，请尝试以下操作：（这将安装列出的依赖项和驱动程序）
sudo apt-get install libnvidia-gl-390:i386
sudo apt-get install libnvidia-gl-390
sudo apt-get install nvidia-driver-390
或者这样：（这将卸载并清除与 Nvidia 相关的任何安装内容并安装驱动程序，同时删除软件包的本地副本以再次下载）
sudo apt-get clean
sudo apt-get purge nvidia*
sudo apt-get autoremove --purge
sudo apt-get install nvidia-driver-390
