当我尝试将 14.10 切换到 systemd 时，我遇到了一种情况：我无法删除软件包“nvidia-prime”，并且它阻止我安装 upstart 或 systemd，所以现在我的机器无法重新启动。我该如何强制 dpkg 删除该愚蠢的软件包？

答案1
我做到了。不得不深入研究那个包脚本
cat /var/lib/dpkg/info/nvidia-prime.postinst
我看到它检查了 /etc/init.d/nvidia-prime 是否存在，所以我创建了它。
touch /etc/init.d/nvidia-prime
然后该软件包诚挚地允许其自行重新安装然后删除。
答案2
这里有一个几乎与您的意图相同的答案的链接。
nvidia-prime 软件包应该可以完美运行。显然，您的 nvidia 安装在某种程度上“做得过头了”。如此处步骤所述：
如果安装有点过度，我会尝试以下操作：
安装 ppa-purge
sudo apt-get purge nvidia*
sudo ppa-purge ppa:xorg-edgers/ppa
sudo 重启
返回终端，只需尝试以下操作：
sudo 添加 apt 存储库 ppa：图形驱动程序/ppa
sudo apt-get 更新
然后是这里：
sudo apt-get 安装 nvidia-358 nvidia-prime
sudo apt-get install --reinstall xserver-xorg
sudo 重启
如果这对您的情况有帮助，请以评论形式回答。
