我在伺服器 (20.04 LTS) 上卸載軟體包時遇到問題。
當我運行時apt remove metricbeat收到此訊息：
root@elk:/home/elk# apt remove metricbeat

The following packages will be REMOVED:

它在這一步驟凍結，ctrl+c ctrl+z 不起作用。我打開另一個 ssh 連線並再次運行apt remove metricbeat並收到以下訊息：
^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 PIDps -aux | grep apt 並殺死了它。然後再次運行刪除命令：
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運行進程：
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
殺死這些進程後，再次執行 package remove 命令並取得：
E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
所以我跑了sudo dpkg --configure -a，它卡在了這一步：
root@elk:/home/elk# dpkg --configure -a

通過 ctrl+c ：

我檢查了 /boot ：

我認為它有一些問題initrd.img-5.4.0-92-generic，我不知道如何解決。這樣的循環一次又一次地發生。
答案1
你要等多久？我知道在它執行的過程中我必須等待幾分鐘update-initramfs: Generating /boot/initrd.img。當它到達時，試著喝杯咖啡，看看電視。
答案2
嘗試update-initramfs在詳細模式下運行，看看它卡在哪個模組上：
update-initramfs -v -u
或者ps可能會顯示目前正在運行哪個鉤子：
ps f | grep initram
