我正在嘗試刪除加密系統中的舊核心。我正在將內核標記為清除，但在我努力之後安裝。
我首先從以前的核心更新中刪除剩餘的臨時文件
$ sudo rm -rv ${TMPDIR:-/var/tmp}/mkinitramfs-*
我目前的版本號碼是4.4.0-127-generic
這是我經過多次嘗試後目前的清單。我試圖保留 127（我目前的版本和 124）
$ dpkg -l | tail -n +6 | grep -E 'linux-image-[0-9]+'
pi linux-image-4.4.0-112-generic 4.4.0-112.135 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
pi linux-image-4.4.0-116-generic 4.4.0-116.140 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
pi linux-image-4.4.0-119-generic 4.4.0-119.143 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
pi linux-image-4.4.0-121-generic 4.4.0-121.145 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-4.4.0-122-generic 4.4.0-122.146 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-4.4.0-124-generic 4.4.0-124.148 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
ii linux-image-4.4.0-127-generic 4.4.0-127.153 amd64 Linux kernel image for version 4.4.0 on 64 bit x86 SMP
所以，假設我嘗試刪除 4.4.0-119
我透過刪除 initrd.img 檔案釋放啟動空間
$ sudo update-initramfs -d -k 4.4.0-119-generic
update-initramfs: Deleting /boot/initrd.img-4.4.0-119-generic
我嘗試清除內核
$ sudo dpkg --purge linux-image-4.4.0-119-generic linux-image-extra-4.4.0-119-generic
dpkg: dependency problems prevent removal of linux-image-4.4.0-119-generic:

這樣做會將核心的狀態改為 pi。這是我之前用來刪除舊核心的方法。我不確定這裡發生了什麼變化。
答案1
查看您收到的錯誤訊息：
dpkg: dependency problems prevent removal of linux-image-4.4.0-119-generic:
linux-signed-image-4.4.0-119-generic depends on linux-image-4.4.0-119-generic (= 4.4.0-119.143).
它告訴您，刪除這些套件後，該套件linux-signed-image-4.4.0-119-generic將具有未滿足的依賴關係。因此，問題的解決方案應該是也刪除此軟體包，因為它屬於您要刪除的核心。
嘗試這個指令：
$ sudo dpkg --purge linux-image-4.4.0-119-generic linux-image-extra-4.4.0-119-generic linux-signed-image-4.4.0-119-generic
答案2
嘗試從 apt 中刪除：
sudo apt remove --purge linux-image-4.4.0-119-generic linux-image-extra-4.4.0-119-generic
