我在卸载服务器（20.04 LTS）上的软件包时遇到问题。
当我运行时apt remove metricbeat收到此消息：
root@elk:/home/elk# apt remove metricbeat

The following packages will be REMOVED:

Progress: [ 80%] [############################################.......]
它在这一步冻结了，ctrl+c ctrl+z 不起作用。我打开另一个 ssh 连接并再次运行apt remove metricbeat并收到此消息：
^Citing for cache lock: Could not get lock /var/lib/dpkg/lock-frontend. It is held by process 1890890 (apt)... 1s
我找到了 apt PID 并将ps -aux | grep apt 其杀死。然后再次运行删除命令：
root@elk:/home/elk# apt remove metricbeat
^Citing for cache lock: Could not get lock /var/lib/dpkg/lock. It is held by process 1891272 (dpkg)... 1s
dpkg 正在运行的进程：
root 1891272 0.0 0.0 11136 5328 ? Ss 14:47 0:00 /usr/bin/dpkg --status-fd 42 --configure --pending
root 1891282 0.0 0.0 2608 608 ? S 14:47 0:00 /bin/sh /var/lib/dpkg/info/linux-image-5.4.0-92-generic.postinst triggered linux-update-5.4.0-92-generic
终止这些进程后再次运行 package remove 命令并获得：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
所以我运行了sudo dpkg --configure -a并且它卡在这一步：
root@elk:/home/elk# dpkg --configure -a

按 ctrl+c ：

我检查了 /boot：

我认为它存在一些问题，initrd.img-5.4.0-92-generic但我不知道如何解决。这种循环一次又一次地发生。
答案1
你要等多久？我知道在它运行的时候我不得不等了好几分钟update-initramfs: Generating /boot/initrd.img。等它到达时，试着喝杯咖啡，看看电视。
答案2
尝试update-initramfs以详细模式运行，查看它卡在哪个模块上：
update-initramfs -v -u
或者ps可能会显示哪个钩子当前正在运行：
ps f | grep initram
