内核升级后 dpkg/dkms 不退出/挂起

Question

我已经升级到最新的内核版本。

升级过程未完成。手动尝试时（在终端上），我得到：

Setting up linux-image-4.13.0-25-generic (4.13.0-25.29) ...
Running depmod.
update-initramfs: deferring update (hook will be called later)
The link /initrd.img is a dangling linkto /boot/initrd.img-4.13.0-25-generic

) points to /boot/vmlinuz-4.13.0-25-generic

run-parts: executing /etc/kernel/postinst.d/dkms 4.13.0-25-generic /boot/vmlinuz-4.13.0-25-generic
(hangs)

按照评论中的建议，我尝试删除 nvidia 驱动程序和内核映像。但这基本上导致了同样的问题：

$ sudo apt-get purge linux-image-4.13.0-25-generic *nvidia*
The following packages will be REMOVED:
  linux-image-4.13.0-25-generic* linux-image-extra-4.13.0-25-generic nvidia-384* nvidia-opencl-icd-384* nvidia-prime*
  nvidia-settings*

Answer 1

对我来说，这与专有的 nvidia 驱动程序（版本 385）有关。我使用“软件和更新 - > 附加驱动程序”选项卡删除了它们。之后，我手动卸载了该linux-image-4.13.0-25-generic软件包：

sudo apt-get remove linux-image-4.13.0-25-generic

并跑了：

sudo apt-get install -f && sudo apt-get upgrade

重新启动后，我的系统正在运行最新的内核，并且能够安装最新的 nvidia 驱动程序。

编辑：

如果进程挂起，显然终止plymouth服务应该会有所帮助（请参阅Launchpad）。在新的终端类型中

sudo pkill plymouth

安装应该继续。

编辑2：

正如在一切正常后提到的 /op 重新安装linux-image-generic软件包以将内核更新到最新版本：

sudo apt-get install linux-image-generic
