autoremove 挂在内核删除上

Question

我正在运行 Ubuntu 17.04 -4.10.0-21-generic系统提示我删除旧4.10.0-19-generic内核，但删除该部分时它挂起linux-image-extra-4.10.0-19-generic。看：

(Reading database ... 235316 files and directories currently installed.)
Removing linux-image-extra-4.10.0-19-generic (4.10.0-19.21) ...
run-parts: executing /etc/kernel/postinst.d/apt-auto-removal 4.10.0-19-generic /boot/vmlinuz-4.10.0-19-generic
run-parts: executing /etc/kernel/postinst.d/dkms 4.10.0-19-generic /boot/vmlinuz-4.10.0-19-generic

有什么建议吗？我尝试重新启动，但它仍然挂起，删除此软件包会阻止任何其他安装。

可能的情况是，这只是需要很长时间并且没有挂起。我遇到了类似的问题，最后在离开它很长一段时间后，我意识到它需要很长时间才能完成并且没有任何输出。这给人一种挂起的感觉，因为通常 Linux 和 apt 都很冗长，并且执行操作所需的时间大致相似。

编辑：经过进一步调查，我相信这是因为apt autoremove（对我们来说不幸的是）足够聪明，可以update-grub在每次修改内核时运行，即使它是一个冗余内核。我sudo update-grub后来通过手动运行意识到了这一点，果然，同样漫长的等待期。

例如，以下是我的自动删除的一些输出：

在我的沮丧中，我输入了一些命令（不是正确的方法，但我们都经历过......），只是为了看看事情是否会做出反应。它没。从输出“Found memtest86+ image: /boot/memtest86+.bin”到“done”大约需要 15 分钟。不知道为什么要花这么长时间，但耐心可能会帮助你，它帮助了我！
